    Purpose

    To evaluate and compare clinical outcomes after femtosecond laser-assisted implantation of 325-degree versus 340-degree arc length intracorneal ring segments (ICRS) in eyes with keratoconus (KCN).

    Methods

    In this prospective non-randomized interventional case series, 23 eyes of 21 patients diagnosed with KCN, underwent femtosecond laser-assisted implantation of two types of ICRS, which included a 325-degree ICRS (Group 325) and a 340-degree ICRS (Group 340). The primary outcome measures were uncorrected distance visual acuity (UDVA), and the secondary outcome measures included corrected distance visual acuity (CDVA), sphere, cylinder, mean refractive spherical equivalent (MRSE), keratometry, vectorial change in corneal astigmatism, and the location of maximum keratometry relative to the corneal apex. The study groups were compared using the primary and secondary outcome measures obtained at postoperative months six and 12.

    Results

    Groups 325 and 340 consisted of 10 and 13 eyes, respectively. The two groups were comparable in terms of parameters measured preoperatively. On comparison to the baseline values, both study groups exhibited a significant increase in UDVA and CDVA measured at postoperative month six (Ps < 0.05) and a significant decrease in the sphere, cylinder, spherical equivalent refraction, and keratometry readings measured at postoperative months six and 12 (Ps < 0.05). No significant differences were observed between the two groups in terms of visual, refractive, and keratometric outcomes at any time point. No intraoperative or postoperative complications were observed in any of the study groups.

    Conclusion

    Both the 325-degree ICRS and the 340-degree ICRS effectively and equally improved visual, refractive, and keratometric outcomes in keratoconic eyes.

    Purpose

    To investigate the effect of static accommodative tasks on intraocular pressure (IOP) of glaucomatous and normal eyes.

    Methods

    Four groups of subjects categorized as primary open-angle glaucoma (POAG), primary angle-closure suspects (PACS), normal age-matched controls, and normal young adults (NYA; age <40 years) were enrolled. The baseline IOPs were measured after the subjects were looking at a distant target for 15 min. Static accommodation was obtained by execution of near vision tasks (reading at 33 cm in daylight [300 lux] for 60 min). IOPs were measured at 15, 30, 45, and 60 min intervals while accommodating and then measured again after 15 min of relaxing accommodation while looking at a distant target.

    Results

    One-hundred and eighteen eyes of 98 subjects were recruited. The study groups consisted of the following categories: 25 POAG (46 eyes), 24 PACS (47 eyes), 25 matched controls (50 eyes), and 24 NYA (48 eyes). Within all groups, the mean IOP decreased throughout the accommodation period at all time points. Maximum IOP reduction after accommodation was detected at the 30-min time among the POAG subjects, at the 45-min time in the PACS and matched control groups, and at 15 min after the relaxation of accommodation in the NYA group. IOP reduction levels showed no statistically significant difference among POAG, PACS, and the normal matched groups in their response to accommodation. However, NYA had significantly lower IOP and greater IOP reduction after the resting period (relaxation of accommodation).

    Conclusion

    Static accommodative tasks can significantly reduce IOP in normal, POAG, and PACS individuals. Encouraging glaucoma patients to practice periodical near vision tasks could be viewed as an adjunctive measure for glaucoma management.

    زمینه و هدف

    افراد شاخص معنوی و واجدین سلامت معنوی در طراز قرآن مجید و تعالیم اسلامی دارای ویژگی های برجسته و ممتازی هستند. آیه مبارکه 29 از سوره رعد، به زیبایی این مصادیق را معرفی می فرماید" «الذین آمنوا وعملوا الصالحات طوبی لهم وحسن مآب»، «آنان که به خدا ایمان آورده اند و کارهای نیکو پرداخته اند، خوشا به احوال آنان و مقام نیکوی آن ها». در این نوشتار، جنبه های مصداقی و الگوهای دینی سلامت معنوی اسلامی به صورت اجمال ارائه شده است.

    روش کار

    مطلب اصلی از پانل ششمین همایش سلامت معنوی اسلامی در اسفند ماه 1397، برداشت و با مطالعه کتابخانه ای تکمیل و تنظیم شده است.

    یافته ها

    در طول تاریخ اسلام از صدر اول تا دوران معاصر شخصیت های والا، دانشمندان الهام بخش، طبیبان و حکیمان خداجوی و خدمت گذار، و انسان های نیک و معنوی فراوانی را در فرهنگ و تمدن اسلام و ایران خواهیم یافت. این مصادیق سلامت معنوی اسلامی، در جنبه های مختلف زندگی، اعم از اخلاقی و تربیتی، علمی و حرفه ای، سیره و سبک زندگی، در زمره الگوها و مصداق های عینی و تاثیرگذار به شمار می روند.

    نتیجه گیری

    انسان در مسیر زندگی خود، به الگوی عملی نیاز دارد تا با اقتدا به او حرکت کند. از این رو، طبیعی ترین، موثرترین و سریع ترین روش تربیتی، روش الگویی، یعنی ارائه نمونه و تربیت عملی است. نقش الگوها، حساس ترین نقش تربیتی است تا آنجا که الگوهای صالح، مردم را به صلاح و تعالی می رسانند و الگوهای فاسد، مردم را به ورطه فساد و تباهی می کشانند. شناخت ویژگی ها و زوایای آشکار و پنهان زندگی الگوها، و معرفی آنان به جامعه، برای ترویج و اشاعه سلامت معنوی اسلامی، دارای ضرورت مبرم است و از سایر شیوه های ترویجی، نافذتر می باشد.

    Background

    The outstanding spiritual persons with spiritual health have prominent and excellent characteristics in the Holy Quran and Islamic teachings. Verse 29 of Raad Sura from the Holy Quran, introduces these instances, beautifully.  “Those who believe in God and work righteousness, is [every] blessedness, and beautiful place of [final] return. The exemplary aspects and religious models of Islamic spiritual health are summarized.

    Methods

    This article prepared from panel of the sixth Islamic Spiritual Health Conference which was held in March 2019 and completed by using library studies.

    Results

    Throughout the history of Islam from the first to the contemporary, we find many prominent personalities, inspirational scientists, physicians and spiritual persons in the Islam and Iran culture and civilization. These examples of Islamic spiritual health are objective and effective models in different aspects of life including ethical, educational, scientific and professional behavior and lifestyle.

    Conclusion

    Human needs a practical model for moving to future. Therefore, the most natural, most effective and fastest method of training is the model method, which presents examples and the practical education. The role of models is the most sensitive of educational role which competent models lead people to excellence and corrupt models lead them to corruption. Recognition of the obvious and hidden characteristics of models life and introducing them to community is needed to promote Islamic spiritual health and is more effective than other promotional methods.

    Randall Schweller is a leading neoclassical realist who has paved the way for the revival of realism through criticizing the structuralist approach of neo-realism. Waltz, Walt, and Mearsheimer have been the major targets of his attacks. This article argues that his main added value to realism is to find a way to respond to internal divisions among realists and weak historical support for many of neo-realist propositions. Within this framework he enters into internal debates among realists about status quo versus revisionist states; explains non-formation of balancing behavior and balance of power in the course of history; pays attention to change in international system ignored by many realists; and rejects the objections against realists for not accounting for international institutions. By including domestic factors in his analysis, his work accounts for the emergence of revisionist states, dynamics of international system, and the significance (or insignificance) of international institutions within a theory of states’ interest and the resulting balance of interests in the international system. This theory can clarify the historical conditions in which realists’ claims can prove to be true. In order to give an account of Schweller’s theoretical endeavors to modify and revive realism, this article analyses his major works and shows that although he could account for inconsistences within realism, his own work with its own problems can add to internal divisions within realist camp.

    Today, theory of control provides a rich methodology and a set of supporting principles and tools for analysis of regional orders and its strategies and actors. Today, anti- systemic groups is a key concept in modern management of regional orders and interconnection between control system and new actors. Despite significant changes in international relations in recent decades the study of regional orders and their control are not at core of theories of international relation. Anti-systemic groups, as one of control variables in the regional orders, particularly in West Asia regional order, as an important strategic region, has been highlighted. Therefore, the core object of current research is to make a response to this question that what is the role and function of anti-systemic groups in order control system of West Asia region? In reply to this question, it can be said that anti-systemic groups will help to operation of control systems, including balance of power, deterrence and compellence, in asymmetrical condition of power and complexity of regional order. So, explaining the problem of offensive and resistant anti-systemic groups, as a mechanism for balancing, deterring and compelling, in West Asia region, is the main aim of this article. This survey concludes by considering the functions of these new actors for attempts to explain the management of new regional order.

    Purpose
    To evaluate corneal changes after collagen crosslinking (CXL) therapy for keratoconus (KCN) using the Galilei dual Scheimpflug analyzer.
    Methods
    This prospective, nonrandomized clinical study included 35 eyes of 32 keratoconus patients who had undergone CXL. The eyes were saturated with riboflavin solution and were subjected for 30 minutes to ultraviolet-A (UV-A) light with irradiance of 3 mW/cm2. Effectiveness of the treatment was assessed by measuring uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), manifest cylinder/sphere, keratometry, pachymetry, posterior and anterior elevations by the Galilei dual Scheimpflug analyzer. Prior to treatment and 8 months after therapy, Scheimpflug analysis was performed using the Galilei system. The four sets of data including keratometry values, pachymetry, elevation parameters and surface indices were statistically analyzed and compared.
    Results
    Mean patient age was 22.3 ± 3.8 years and mean postoperative follow-up was 8.1 ± 3.2 months. There was a significant increase in UCVA (0.54 ± 0.35 Log MAR preoperatively to 0.49 ± 0.34 LogMAR postoperatively, P = 0.01) and BCVA (0.21 ± 0.19 Log MAR preoperatively to 0.16 ± 0.17 LogMAR postoperatively, P = 0.01). Mean cycloplegic spherical equivalent refractive error was −4.13 ± 2.65 Diopter (D) preoperatively and − 4.67 ± 2.96 D postoperatively (P
    Conclusion
    Corneal stabilization could be achieved by collagen crosslinking therapy for keratoconus in terms of corneal thickness, keratometry values, elevation parameters and surface indices.

    Purpose
    To compare distant and near visual function after cataract surgery with implantation of Crystalens HD or Tek-Clear as accommodating intraocular lenses (IOLs), versus SA60AT as a standard IOL.
    Methods
    The study included 62 eyes of 58 patients divided into three groups using three different IOLs: Crystalens HD (Bausch and Lomb, NY, USA), Tek-Clear (Tekia, CA, USA) and SA60AT (Alcon, TX, USA) were implanted in 23, 14 and 25 eyes, respectively. Corrected distant visual acuity (CDVA), uncorrected and distance corrected near visual acuities (UCNVA and DCNVA), near point of accommodation (NPA), spectacle freedom and patient satisfaction were assessed six months postoperatively and compared between the three groups.
    Results
    After 6 months, all patients showed significant improvement in CDVA with no significant difference among the study groups. However, UCNVA and DCNVA were significantly better in patients implanted with accommodating IOLs. NPA was closest in the Crystalens HD group, followed by Tek Clear and monofocal SA60AT (P
    Conclusions
    Accommodating IOLs (Crystalens HD and Tek-Clear) effectively reduce the necessity for spectacles after cataract surgery.

    Purpose
    To compare ultrasound pachymetry and Orbscan II for measurement of central corneal thickness (CCT) in normal eyes.
    Methods
    The current study was performed at Labbafinejad Medical Center (LMC), Tehran, Iran. Three hundred eyes from 150 healthy individuals referred for keratorefractive surgery were assessed first by Orbscan II and then by ultrasound pachymetry, and CCT values were recorded and compared.
    Results
    Overall, Orbscan II overestimated CCT as compared to ultrasound pachymetry by about 2.4% (mean values 547.6 ± 34.7 versus 534.8 ± 34.7, respectively, P < 0.001). The difference was more significant when CCT was less than 500 microns (mean values 493.2 ± 16.9 versus 479.9 ± 15.6, mean overestimation: 2.6%, P < 0.001). There was good linear correlation between the two methods (Pearson's correlation r = 0.968, P < 0.0001).
    Conclusion
    Orbscan II has good correlation with ultrasound pachymetry for measurement of CCT in normal eyes; however Orbscan II should not be used to evaluate corneal thickness before keratorefractive surgeries, as it tends to overestimate corneal thickness and may result in undesirable, low residual stromal thickness.

    Background
    Ramadan fasting may alter a variety of physiological parameters which by themselves influence ocular system. Here, we review the effects of Ramadan fasting on the health and function of the eye.
    Materials And Methods
    Literature records in PubMed/MEDLINE, Web of Science, EMBASE, Google Scholar, and Iran Medex databases as well as proceedings of related meetings from January 1986 to March 2014 were systematically reviewed. The search key words was based on the terms “Ramadan Fasting,”“Ramadan,” “Islamic Fasting,” “Fasting in Ramadan” accompanied with one of the eye, tear drop, myopia, intraocular pressure (IOP),tear break up time, basal tear secretion, refractive error, and visual acuity.
    Results
    Predawn water loading and dehydration in the evening are shown to increase and decrease IOP and tear secretion, respectively. Ocular blood flow is changed in Ramadan fasting, and patients with ocular vein occlusion may experience more frequent attacks. There are no or minimal fluctuations in visual acuity and refractive errors, but most of them are decompensated after Ramadan.
    Conclusion
    Although the influence of fasting in different eye parameters is evaluated in several studies, there are no or only limited studies conducted on patients suffering from glaucoma,damage to ophthalmic vasculature, tear dysfunction, and minimal visual acuity. Such studies are required to make a definite decision before fasting is declared harmless to these patients.

    Purpose
    To compare corneal higher-order aberrations (HOAs) between normal and keratoconic eyes, and to investigate the association between elevation-based corneal topographic indices and corneal wavefront data in the latter group.
    Methods
    In this cross-sectional comparative study, 77 normal right eyes of 77 control subjects and 66 eyes of 36 keratoconic patients were included. In each eye, elevation-based corneal topographic indices including mean keratometry readings, best-fit sphere, maximum elevation, and 3-mm and 5-mm zone irregularity indices were measured using Orbscan II. The Galilei Scheimpflug analyzer was used to measure HOAs of the corneal surface. The independent student t-test was used to compare HOAs between the study groups. Spearman correlation was used to investigate possible associations between Orbscan and Galilei data in the keratoconus group.
    Results
    All Zernike coefficients up to the 4th order except for horizontal trefoil, and vertical and horizontal tetrafoil were significantly greater in the keratoconus group than normal eyes (P)

    Background and
    Purpose
    comparison of the academic situation in various national and international universities may be done as ranking. Improving the quality of university education is an integral part of higher education management. Accurate measurement of specific indicators is an essential precondition of access to education systems quality. Current ranking indicators have not been adequately about teaching and the review on the world ranking systems is needed. The current study has been designed and implemented with the aim of explanation and identification of the teaching ranking Criteria in Iran and world universities.
    Methods
    Systematic review of the literature for information on the latest events in the world rankings and teaching criteria via systematic searching of the databases, Academic journals and published books, national and international official reports, papers presented at national and international conferences and journals, research and evaluation projects and academic theses, reports and news related to the ranking were done.
    Results
    European University Association has published a report in 2013 that in addition to analysis of the current status of ranking systems, discuss on the new tool and new project of teaching ranking. Teaching Indicators in this project include: expenditure on teaching as a proportion of total expenditure, graduation rate, interdisciplinary of programs, relative graduate unemployment rate, time to degree, investment in laboratories, the proportion of staff with doctorates, the inclusion of issues relevant to employability in the curriculum, computer facilities comprising hardware, internet access, field-specific software and access to computer support, and student gender balance. Assessment of higher education learning outcomes and students satisfactory indicators are mentioned in this project, too.
    Conclusions
    Due to the globalization of education and development of academic institutions, the necessity of academic performance evaluation is shown. Teaching ranking indicators as a mechanism for analyzing the performance of universities and judges about them are important. Collection and delivery of the indicators for promotion of higher education, and achieve a good position in the world rankings, is a small step that can be taken as a prelude to the development of native teaching ranking standards.

    Purpose
    To investigate the outcomes of keratolimbal allograft (KLAL) for treatment of total limbal stem cell deficiency (LSCD).
    Method
    Patients with total LSCD and adequate tear production were included. A total of 27 KLAL procedures were performed in 21 eyes of 20 patients with LSCD. Immunosuppression was achived using mycophenolate and cyclosporine. Main outcome measure was improvement in vision; in addition, KLAL survival and post operative complications were studied.
    Results
    Mean follow up period was 22.14±11.83 months (range 6-39). Mean visual acuity improved from 2.53± 0.21 to 1.49±0.77 LogMAR (P<0.0001). Six KLALs never re-epithelialized and were considered as primary failures. Mean KLAL survival was 14.23±1.5 months. Graft survival rate was 61.9% at 1 year and 31% at 20 months. Complications included corneal ulcers in 6, glaucoma in 2 and scleral thining in 1 case.
    Conclusion
    Keratolimbal allograft surgery is successful in the short term for visual rehabilitation of patients with total limbal stem cell deficiency.

    To report the indications and techniques of corneal transplantation at a tertiary referral center in Tehran over a 3-year period.
    Methods
    Records of patients who had undergone any kind of corneal transplantation at Labbafinejad Medical Center, Tehran, Iran from March 2004 to March 2007 were reviewed to determine the indications and types of corneal transplantation.
    Results
    During this period, 776 eyes of 756 patients (including 504 male subjects) with mean age of 41.3±21.3 years underwent corneal transplantation. The most common indication was keratoconus (n=317, 40.8%) followed by bullous keratopathy (n=90, 11.6%), non-herpetic corneal scars (n=62, 8.0%), infectious corneal ulcers (n=61, 7.9%) previously failed grafts (n=61, 7.9%), endothelial and stromal corneal dystrophies (n=28, 3.6%), and trachoma keratopathy (n=26, 3.3%). Other indications including Terrien''s marginal degeneration, post-LASIK keratectasia, trauma, chemical burns, and peripheral ulcerative keratitis constituted the rest of cases. Techniques of corneal transplantation included penetrating keratoplasty (n=607, 78.2%), deep anterior lamellar keratoplasty (n=108, 13.9%), conventional lamellar keratoplasty (n=44, 5.7%), automated lamellar therapeutic keratoplasty (n=8, 1.0%), and Descemet stripping endothelial keratoplasty (n=6, 0.8%) in descending order. The remaining cases were endothelial keratoplasty and sclerokeratoplasty.
    Conclusion
    In this study, keratoconus was the most common indication for penetrating keratoplasty which was the most prevalent technique of corneal transplantation. However, deep anterior lamellar keratoplasty is emerging as a growing alternative for corneal pathologies not involving the endothelium.

    Purpose
    To determine the rate and risk factors of vitreous loss during phacoemulsification in patients with cataracts operated by ophthalmology residents and fellows at Labbafinejad Medical Center.
    Methods
    This prospective descriptive study included consecutive patients with cataracts undergoing phacoemulsification over a one year period. All patients were operated under local or general anesthesia using the divide and conquer technique. Preoperatively, all patients underwent a complete ocular examination including measurement of visual acuity, slitlamp biomicroscopy, intraocular pressure measurement, and dilated funduscopy. Main outcome measures included the rate of posterior capsular rupture and vitreous loss as well as associated risk factors such as surgical experience, ocular and systemic conditions, and type and severity of the cataract.
    Results
    Overall, 767 eyes of 767 patients with mean age of 63.7±10.3 (range, 25-91) years were operated. The overall rate of vitreous loss was 7.9% which was 5-fold greater in the hands of residents as compared to fellows. Among different factors, older age, female sex, small pupil, small capsulorrhexis, presence of pseudoexfoliation, and high myopia were significantly associated with vitreous loss. The highest rate of vitreous loss occurred in patients with dense nuclear cataracts.
    Conclusion
    Considering the higher rate of vitreous loss in patients operated by ophthalmology residents; patients with known risk factors for vitreous loss should better be operated by more experienced surgeons.

    هدف
    ارزیابی تاثیر میزان واکیوم و فلو ریت (flow rate) بر چگالی یاخته های اندوتلیوم قرنیه در عمل فیکوامولسیفیکیشن.
    روش پژوهش: در این کارآزمایی بالینی 60 چشم از 60 بیمار با کدورت متوسط عدسی (اسکلروز هسته ای به میزان +3)، به طور تصادفی در دو گروه مساوی تحت جراحی قرار گرفتند. همه جراحی ها توسط یک جراح باتجربه و با شیوه Stop & Chop توسط ماشین فیکو Sovereign (AMO) و برنامه ستاره سفید (White Star) انجام شدند. در گروه واکیوم پایین، در مرحله Chop، واکیوم 200 میلی متر جیوه و فلو ریت 20 میلی لیتر در دقیقه و در گروه واکیوم بالا، واکیوم 400 میلی متر جیوه و فلو ریت 40 میلی لیتر در دقیقه برقرار شد. سایر مولفه های ماشین فیکو در سایر مراحل، در دو گروه مشابه بودند. چگالی یاخته های اندوتلیوم قرنیه قبل از عمل و هفته های 1، 6 و 12 بعد از عمل توسط میکروسکوپ اسپکولار اندازه گیری و بین دو گروه مقایسه شد. ارتباط انرژی اولتراسوند و فلوی هیدروداینامیک با میزان کاهش یاخته های اندوتلیوم در مجموع دو گروه، با آنالیز رگرشنی چندگانه مورد ارزیابی قرار گرفت.
    یافته ها
    بعد از 12 هفته، میانگین کاهش یاخته های اندوتلیوم قرنیه در گروه واکیوم پایین و بالا، به ترتیب 0/4±0/9 درصد و 6/4±6/9 درصد بود (6/0=P). میانگین قدرت اولتراسوند در گروه واکیوم پایین و بالا، به ترتیب 3/4±2/9 درصد و 6/4±1/13 درصد بود (001/0=P). میانگین مدت فیکو در گروه واکیوم پایین و واکیوم بالا، به ترتیب 0/1±28/1 و 6/0±88/0 دقیقه بود (04/0=P). دو گروه از نظر کل انرژی اولتراسوند و کل حجم مایع مصرف شده از بطری (توربولانس)، تفاوت آماری معنی داری نداشتند. تحلیل رگرشنی چندگانه نقش انرژی اولتراسوند در میزان کاهش یاخته های اندوتلیوم قرنیه را به طور معنی داری تایید نمود (001/0=P و 936/0=2(R ولی ارتباط توربولانس با میزان کاهش یاخته های اندوتلیوم قرنیه به لحاظ آماری معنی دار نبود (1/0=P و 924/0=2R).
    نتیجه گیری
    کاهش یاخته های اندوتلیوم قرنیه بعد از عمل فیکوامولسیفیکیشن ارتباطی با میزان واکیوم و فلو ریت ندارد. لذا توصیه می کنیم که جهت انجام فیکو، ضمن استفاده از حداقل قدرت، جراحان کم تجربه از شیوه واکیوم پایین استفاده کنند ولی جراحان باتجربه می توانند برای کاهش مدت فیکو، از شیوه واکیوم بالا استفاده نمایند.

    Purpose
    To evaluate the effect of vacuum and flow rate on endothelial cell loss after high versus low vacuum phacoemulsification.
    Methods
    This randomized clinical trial was performed on 60 eyes of 60 patients with moderate lens opacity (nuclear sclerosis 3+). All surgeries were performed by one experienced surgeon using stop and chop technique with Sovereign white star machine (AMO). Patients were randomly assigned to high and low vacuum techniques in equal numbers. The machine was set on 400 mmHg vacuum and 40 ml/min flow rate in the high vacuum group and on 200 mmHg vacuum and 20 ml/min flow rate in the low vacuum group during the chop stage. All other parameters were similar in both groups. Phacotime multiplied by average ultrasound power was defined as total ultrasound energy. Specular microscopy was performed before and 1, 6 and 12 weeks after the operation.
    Results
    After 12 weeks, mean endothelial cell loss was 9.0±4.0% versus 9.6±4.6% in the low and high vacuum groups, respectively (P=0.6). Mean ultrasound power was 9.2±4.3% and 13.1±4.6% in the low and high vacuum groups, respectively (P=0.001). Mean phacotime was 1.28±1.0 minutes in the low vacuum group versus 0.88±0.6 minutes in the high vacuum group (P=0.04). Total ultrasound energy and total fluid volume used (turbulence) during phacoemulsification was similar between the two study groups. Total ultrasound energy was the most powerful predictor of endothelial cell loss (R2=0936, P=0.001), but turbulence was not a significant predictor (R2=0.924, P=0.1).
    Conclusion
    No significant difference in endothelial cell loss was found between low and high vacuum techniques. This study supports advice to junior surgeons to choose lower hydrodynamic phaco machine parameters; experienced surgeons can choose higher parameters to reduce phacotime

    هدف
    ارزیابی میزان بروز پارگی کپسول خلفی و عوامل خطرساز مرتبط با آن در بیمارانی که طی آبان 1385 تا آبان 1386 در بیمارستان لبافی نژاد تحت عمل جراحی فیکوامولسیفیکیشن قرار گرفتند.
    روش پژوهش: هر چشمی که تحت عمل جراحی فیکوامولسیفیکیشن قرار می گرفت از نظر پارگی کپسول خلفی و عوامل مرتبط با آن در اتاق عمل مورد ارزیابی قرار می گرفت.
    یافته ها
    در این مدت 767 بیمار شامل 393 مرد و 374 زن با میانگین سنی 0/12 7/62 سال (96-6 سال) تحت جراحی فیکوامولسیفیکیشن قرار گرفتند که 3/7 درصد بیماران دچار پارگی کپسول خلفی شدند. میانگین سنی بیماران دچار پارگی کپسول خلفی 9/9±7/66 سال (85-45 سال) بود که شامل 32 زن (5/61 درصد) و 20 مرد (5/38 درصد) بودند. میانگین وزن افراد با و بدون این عارضه، 9/90/75 در مقابل 2/90/71 کیلوگرم بود (02/0P=). فراوانی ایجاد پارگی کپسول خلفی توسط دستیاران 4/13 درصد و توسط فلوها 2/1 درصد بود (001/0P<). در 3/13 درصد افراد، اندازه کپسولورکسیس کم تر یا مساوی 5 میلی متر یا قطر مردمک با حداکثر گشادشدگی در خلال جراحی، کم تر یا مساوی mm6 بود. روش جراحی، نوع دستگاه فیکو یا زمان جراحی تاثیری در ایجاد این عارضه نداشتند. اکثر موارد پارگی کپسول خلفی (50 درصد) در مرحله فیکوامولسیفیکیشن ایجاد شده بودند و بروز آن در بیمارانی که پیش از آن ویترکتومی شده بودند؛ به طور محسوسی افزایش داشت. دیابت و فشار خون بالا رابطه ای با پارگی کپسولی نداشتند.
    نتیجه گیری
    با توجه به شیوع آب مروارید و استفاده روزافزون از روش های جراحی فیکوامولسیفیکیشن و شیوع بالای عوارض به ویژه در دوره آموزشی، شناخت عوامل خطرساز و توجه به آن ها و آموزش کافی دستیاران می تواند تاثیر به سزایی در بهبود نتایج و کاهش عوارض جراحی داشته باشد.

    Purpose
    To report the rate of vitreous loss during phacoemulsification and its contributing risk factors in patients operated on at Labbafinejad Medical Center.
    Methods
    This prospective comparative descriptive study included patients with cataract undergoing phacoemulsification by ophthalmology residents or cornea fellows from November 2006 to November 2007. All patients underwent a complete ocular examination including visual acuity, slitlamp examination, and dilated funduscopy, preoperatively. Phacoemulsification was performed under local or general anesthesia using Divide & Conquer technique. Main outcome measures included posterior capsular tear and vitreous loss and predisposing factors such as surgeon’s experience, ocular and systemic conditions, and type and severity of the cataract.
    Results
    Overall 767 patients including 393 male and 374 female subjects with mean age of 62.7±12.0 (range 6-96) years were studied. The overall rate of vitreous loss was 7.3% which was 5-fold higher in the hands of residents than fellows. Patients’ age and female sex, small capsulorrhexis, small pupil, pseudoexfoliation, and high myopia were other significant risk factors. The highest rate of vitreous loss occurred in patients with dense nuclear cataracts.
    Conclusion
    Since ophthalmology residents had a higher rate of vitreous loss, patients with risk factors such as pseudoexfoliation, high myopia, and dense nuclear cataracts are better operated by more experienced surgeons.

    Purpose
    To report the outcomes of penetrating keratoplasty (PKP) in patients with macular corneal dystrophy (MCD).
    Methods
    This retrospective case series includes consecutive patients with MCD who underwent PKP from 1986 to 2006 with at least 6 months'' follow-up. Main outcome measures included best spectacle-corrected visual acuity (BSCVA), postoperative astigmatism and graft survival.
    Results
    Sixty-two eyes of 39 patients with mean age of 34.0±10.5 (range 13-58) years at the time of keratoplasty were included for analysis. After a mean follow-up period of 52.0±47.3 (range 6-190) months, BSCVA improved from 1.4±0.4 logMAR (4/100) preoperatively to 0.2±0.3 logMAR (20/32) at final follow-up (P < 0.001). Mean postoperative BSCVA was 0.15±0.40 logMAR in patients (36 eyes) aged less than 35 years at the time of surgery as compared to 0.26±0.25 logMAR in subjects (26 eyes) older than 35 years (P=0.005). Final astigmatism was comparable with different suturing techniques including separate, continuous, and combined sutures (P=0.9). All grafts were clear at final follow-up except a single case of MCD with visually insignificant recurrence. Episodes of immunologic graft rejection occurred in 12 eyes (19.4%) but none led to graft failure.
    Conclusion
    PKP for MCD entails favorable outcomes in terms of graft survival and visual improvement. Final visual acuity seems to be better when transplantation is performed before the age of 35 years.

    Purpose
    To evaluate anterior chamber aspirates at the conclusion of phacoemulsification and intraocular lens implantation (PE+IOL) for bacterial and fungal contamination.
    Methods
    We prospectively evaluated 80 eyes of 80 patients undergoing routine PE+IOL by performing bacterial and fungal culture on aspirates obtained from the anterior chamber at the end of the surgery.
    Results
    Anterior chamber fluid aspirates were positive for bacteria in 5 eyes (6.33%) with coagulase-negative staphylococcus being the most common organism (three eyes). No instance of positive fungus culture was observed. One of the culture-positive eyes developed postoperative uveitis which resolved during a week of treatment with topical corticosteroids and antibiotics. None of the eyes developed endophthalmitis.
    Conclusion
    In the current series, the rate of anterior chamber contamination by bacteria at the end of phacoemulsification was in the lower range reported by previous studies

    Purpose
    To report the early results of transplantation of autologous limbal stem cells cultivated on amniotic membrane (AM) in patients with total unilateral limbal stem cell deficiency (LSCD).
    Methods
    Four eyes of 4 patients with total unilateral LSCD confirmed with impression cytology underwent transplantation of autologous limbal stem cell cultivated on AM. At each follow up visit, a complete eye examination with special attention to recurrence or regression of vascularization, corneal opacification, and epithelial defect healing was performed. Digital imaging was performed at each follow up visit. Impression cytology was repeated in all cases after surgery.
    Results
    The patients were followed for 5-13 months. Visual acuity improved in all cases. Decrease in corneal opacification and vascularization was obvious in 3 cases with coverage of the cornea with corneal epithelium. Sectoral conjunctivalization was evident in these 3 cases, however the corneas were ready for transplantation. The procedure failed in one case with total corneal conjunctivalization.
    Conclusion
    Transplantation of autologous stem cells cultivated on AM seems to be an effective way for total LSCD. More definite judgment needs longer follow up together with long-term results of corneal transplantation in these patients.

    Internal evaluation has started in I 995 in various educational groups of different medical universities. Currently. more than 120 groups are involved in this project. The faculty members have a key role in the process as the main elements of internal evaluation.Internal evaluation was not only helpfill in identifying different practical aspects of education, but also had a prominent role in raising several questions about methodology, objectives, effectiveness and other dimensions of evaluation.Is the so-called internal evaluation consistent with the scientific criteria of evaluation? Could any better alternative method be found to perform this evaluation in the universities? Does the result of the internal evaluarion help the promotion of the education quality?Many of these questions could be answered by comparing the current evaluations with program evaluation standards.In this article, the program evaluation standards are considered and the current situation of internal evaluation in medical education units is compared with those standards. The defects of the current evaluations are assessed and necessary recommendations are presented.

    Today, through out the world, medical education has two critical needs: need for structural reform and innovative plans and then need for social accountability in terms of educational program quality and its effectiveness. Educational assessment and accreditation could be considered as operational (executive) strategy to meet both needs. Of outmost important as the first toward educational assessment and accreditation is the task of specifying standards for medical education both in terms of the institution and the educational program of the institution. Since these standards constitute a new framework against which the medical institutes can measure themselves.Here, in this article we have briefly reviewed the process of developing these standards by AMFEM (in Mexico) and by WFME at an international level. We have tried to underlie two critical features common in both processes. First, the importance levels to defining the physicians' role in terms of what the society or better say, the health care system (as the representative of social health requirement) expects from a good physician. Second, the thoughtful attempt to involve as many experts as possible in the process of developing the standards and providing opportunities to discuss the result of each stage of the specifying standard process.
