Comparison of colour vision in different types of deviation

Purpose: The aim of the present study is to compare the colour vision in different types of deviation. 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 Colour vision 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 type of deviation. It shows that colour vision will be deteriorated more in Esotropia as compared to Exotropia Conclusions: Deterioration of colour vision is observed more in Esotropia as compared to Exotropia.
