Visual Acuity Comparison of Alternate Esotropia for Different Amount of Deviation

Abstract

Purpose: Aim of the present study is to compare visual acuity in different amounts of deviation of Alternate Esotropia. Methods: Pilot, cross sectional, observational study was performed at tertiary eye care centers. Subjects with Ocular deviation between 10 to 40 prism diopters, Corrected distance Visual Acuity should be greater than 6/18 and Age should be between 10 to 40 years of age were included in the study. Visual Acuity was assessed with Log Mar chart. Results: 30 subjects were included in the study. Out of that, 16 subjects were in the age group of 11-20 years, 12 subjects were in the age group of 21-30 years and 2 subjects were in the age group of 31-40 years. 60% subjects were Female and 40% subjects were Male. The mean visual acuity was considered in each amount of deviation. It shows that maximum acuity is deteriorated in the ocular deviation of 31-40 prism diopters of Alternate Esotropia. Conclusion: As the amount of ocular deviation increases, visual acuity will be more deteriorated in cases of Alternate Esotropia.
