To investigate the effect of topical Polyvinylpyrrolidone‑iodine (PVP‑I) 0.6% on the clinical course of adenoviral keratoconjunctivitis compared with PVP‑I 1% and artificial tears.

We prospectively enrolled all patients over 18 years of age with a polymerase chain reaction (PCR)‑confirmed diagnosis of adenoviral keratoconjunctivitis who presented to the hospital between November 2022 and June 2023. Patients were randomized into 3 groups: artificial tears (control), PVP‑I 1%, and PVP‑I 0.6% eye drops, 4 times daily for 5 days. Clinical signs at presentation and at 6 follow‑up visits during the 1st 3 weeks of the acute phase were recorded. Patients were also followed up at 1 and 3 months.

Ninety‑four patients completed the study, of which 30, 31, and 33 were in the control, PVP‑I 1%, and PVP‑I 0.6% groups, respectively. The mean age of the patients was 37.2 years (interquartile range: 25-46). The PCR result was positive in 75.6% of patients with the clinical suspicion. PVP‑I, regardless of the concentration, was superior to the artificial tears in terms of time to resolution of lid swelling, discharge, and incidence of subsequent subepithelial infiltrates (P < 0.05). However, a concentration of 0.6% was equivalent to 1%. No significant adverse events were reported in any group.

The PVP‑I 0.6% topical drops are safe and well tolerated in patients with acute adenoviral keratoconjunctivitis. It can be substituted for the 1% solution as it has comparable effects in improving the clinical course and reducing subsequent complications.

To evaluate the effect of night shifts on the biomechanical properties of the cornea using Scheimpflug camera‑based imaging (Corvis and Pentacam).

Thirty‑four participants from the medical staff who had at least six night shifts per month as a case group and fifty‑two participants as a control group participated in the study. The biomechanical characteristics of the cornea using the Corvis device and the topographical characteristics of the cornea using the Pentacam device were investigated in the participants.

The main indices of corneal biomechanics including Corvis Biomechanical Index (0.17 ± 0.18 vs. 0.15 ± 0.14; P = 0.66 [adjusted] and 0.66 [unadjusted]) and Tomographic and Biomechanical Index (0.16 ± 0.19 vs. 0.14 ± 0.19; P = 0.78 [adjusted] and 0.63 [unadjusted]) were not significantly different between case and control groups.

Our study showed that night shifts do not independently affect corneal biomechanical indices.

To evaluate the psychometric properties of the Persian version of quality of life impact of refractive correction (QIRC) questionnaire and its utility in assessment of refractive error‑related quality of life (QoL) following photorefractive keratectomy (PRK).

Patients with low‑to‑moderate myopia (−0.75 to − 6.0) were enrolled in this study. Standard alcohol‑assisted PRK was performed in all patients. The QIRC questionnaire was translated into a Persian version using the standard method. Patients completed QIRC questionnaire preoperatively and 3‑month postoperatively. A group of patients completed the questionnaire twice preoperatively. Psychometric properties were evaluated by internal consistency (Cronbach’s α), item‑total correlation, and known group construct validity. Intraclass correlation coefficient (ICC) were used to examine the repeatability.

One hundred forty‑seven patients(60 males and 87 females) with a mean age of 26.3 ± 5.5 (range, 18–39) years were enrolled. Cronbach’s α for total score was 0.923. Item‑total correlation was above 0.3 for all items. ICC was 0.978 for total score. Preoperatively, predominantly contact lens wearers showed significantly better total QIRC score than predominantly spectacle wearers (P = 0.017), which showed good known group validity. Total QIRC score significantly increased from 41.31 ± 6.69 preoperatively to 50.47 ± 7.26 postoperatively (P < 0.0001). Improvement in total QIRC score was observed both in contact lens wearers and spectacle wearers.

The Persian version of QIRC questionnaire is a valid and reliable tool. Refractive error‑related QoL assess by QIRC was significantly improved after PRK in an Iranian population.

 Military activities cannot be classified as pure isometric or pure dynamic exercise. The effects of these activities on intra ocular pressure (IOP) have not been investigated so far.

 The current study aimed to evaluate the short-term effects of military activities on IOP.

Following a cross-sectional design, this study was conducted on 44 soldiers in the Islamic Republic of Iran Army. Soldiers’ heart rate and IOP were recorded before marching activities at rest, immediately after marching, and 30 minutes after the march. The measurements were repeated in the same process in 3 months. The marching activity was the same for all participants and took 60 minutes.

 In total, 44 soldiers were studied, with a mean age of 21.80 ± 1.56 years. The IOP measurements before, immediately after, and 30 minutes after the marching were significantly different. IOP was significantly lower after the march (P < 0.001), and 30 minutes after the march, it was increasing gradually. The same results were observed in the IOP measurements 3 months later. We found no association between IOP after marching and heart rates before and after marching. Also, no significant association was observed between IOP and age.

 IOP was significantly decreased after marching, but it was transient. The results indicate that the dynamic component in military marches is more prominent than isometric parts.

To evaluate ocular movement disorders after scleral buckling surgery (SBS) for retinal detachment. In this prospective, observational, case series, 206 patients (206 eyes) with rhegmatogenous retinal detachment who underwent SBS and investigated at the strabismus ward of Farabi Eye Hospital in Iran between November 2011 and November 2014 were assessed. Patients were followed from 6 to 36 months after SBS to evaluate for strabismus. Logistic regression analysis test and SPSS software version 20 were used for statistical analysis. From 206 patients, 56.8% were male, and 33.2% were female. For scleral buckle in 44.7% of patients, silicone band and tire (SBT) was used, and in 55.3%, a sponge. Among all patients, seven (3.39%) exhibited ocular movement disorder. There was no significant relation between type of buckle (P ¼ 0.65) or the location of buckle (P ¼ 0.56) and movement disorder. Ocular movement disorder is one of the main complications after SBS without specific association between the type and location of exoplanet.

PurposeTo determine the effect of night-time working on dry eye signs and symptoms.
MethodsA total of 50 healthy subjects completed a dry eye questionnaire and underwent clinical examinations including basic Schirmer's test and tear breakup time (TBUT) test on two consecutive days, before and after the night shift (12-hrs night-shift).
ResultsAll dry eye symptoms were aggravated significantly after the night shift (P ConclusionOur study showed that night-time working can cause tear film instability and exacerbation of dry eye symptoms.

To determine the types and frequency of ocular conditions simulating retinoblastoma (pseudo‑retinoblastoma) at Farabi Eye Hospital, Tehran, Iran. We reviewed data of patients who were referred with a diagnosis of retinoblastoma to Farabi Eye Hospital oncology clinic, from January 2009 to July 2013. Examination under general anesthesia was performed for all patients. Other investigations, such as ultrasonography, were performed as required. Of a total of 331 patients (aged 1‑60 months), 138 (42%) were found to be suffering from a benign disorder. Among these pseudo‑retinoblastoma cases, Coats’ disease was the most prevalent codition (n = 36, 26%); persistent hyperplastic primary vitreous (PHPV) and familial exudative vitreo‑retinopathy (FEVR) were the next two common pseudo‑retinoblastoma cases in our series. The rate of misdiagnosis upon referral to our center was close to 40%. The most common pseudo‑retinoblastomas entities include Coats’ disease, PHPV and FEVR. An accurate diagnosis is essential for management of pseudo‑retinoblastoma cases.

to introduce five different type of orbital involvement by hydatid cyst in 8 consecutive patients. DESIGN: descriptive case series. Herein 8 patients with slowly progressive proptosis from 2 to 4months earlier at their first presentation are introduced. Complete ophthalmic examinations were done. Complete blood count, serologic test, ESR (erythrocyte sedimentation rate), CT scan and MRI were requested. Surgical removal of the lesions performed in all patients. The hydatid cysts found in the extraconal (2 patients) and intraconal space (3 patients), lacrimal gland (1 patient), medial rectus (1 patient) and intraosseous of orbital wall (1 patient). The diagnosis of the isolated orbital hydatid cyst without any lesion in other parts of the body was confirmed in all patients. The recurrence was not observed in any patients during 2 – 6 years follow up. Although the most common site of involvement of orbital hydatid cyst is intraconal, it can invade various locations within the orbit.
