Purpose: The aim of the present study is to correlate the effect of colour vision in the presence of ocular deviation.
Methods: A pilot, cross-sectional, observational study was performed at tertiary eye care centers. Subjects with an 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 Munsell 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. Mean scores of visual parameters were taken. In 50 % of cases, colour vision was found normal, 33 % were having mild tritanopia and 17% were having moderate tritanopia.
Conclusions: In cases of ocular deviation, mild to moderate tritanopia can occur.
