Prevalence and Characteristics of Accommodative Esotropia at Nikookari Eye Center form 2004 to 2009

To study the prevalence and characteristics of accommodative esotropia (AET). In a descriptive analytic study records of all patients referred from 1383 to 1388 to the strabismus clinic at Nikookari Eye Center were reviewed and demographic data such as age, gender, refractive error, type of AET, mean deviation and amblyopia were analyzed. A total of 2,146 patients were referred during this period. AET comprised 142 (11.55%) patients. 35.9% of these patients were male and 64.1 % were female. Mean age at presentation was 5.85±4.4 years.The frequency of refractive accommodative ET (RAET), non-refractive accommodative ET (NRAET), partially accommodative ET (PAET) were 82 (57.7%), 7 (4.9%) and 53 (37.3%), respectively. Overall, 69 (48.6%) patients were amblyopic and spherical equivalent refractive error was +4.22±1.82 D. Inferior oblique overaction (IOOA) and dissociated vertical deviation (DVD) were seen in 5 (3.5%) and 2 (1.4%) of patients respectively. RAET is the most common and NRAET is the least common form of AET.Amblyopia is common in AET. The prevalence of associated findings such as DVD and IOOA is low.
