Effect of Colour Vision in Different Amount of Deviation of Esotropia
Journal Title: Ophthalmology and Vision Science - Year 2018, Vol 2, Issue 1
Abstract
Purpose: The aim of the present study is to compare the effect of colour vision in different amount of deviations in Esotropia. Methods: A 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. Colour vision was assessed with Fransworth D 15 colour vision test. 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 colour vision was considered in each amount of deviation. It shows that colour vision will be deteriorated more as ocular deviation increases in cases of Esotropia. Conclusions: In ocular deviation of Esotropia, as amount of deviation increases, Colour vision decreases gradually. Mild to Moderate Tritanopia occurs in increased amount of deviation.
