Abstract
PURPOSE: - To determine the prevalence of colour vision defect and its correlation with amblyopia and refractive error in school going children. Method: - In this population based prospective, cross-sectional study, 4057 children were examined from the random school selected from different areas of Bhuj, Ahmedabad, Modasa and Surendranagar from 6-16 years of age. A complete eye examination was conducted which includes detailed History, Visual acuity, Colour vision assessment, Refractive error measurement, Ocular deviation determination, Accommodation and Convergence and lastly Anterior and Posterior segments evaluation. Children who could not answer 4 or more plates correctly, then child was consider as colour vision deficient. Amblyopia was detected by taking pinhole visual acuity which was lesser than 0.4 in LogMAR. Ocular disease condition was assessed Results: - Color vision deficiency (CVD) was detected in 20 children indicating a prevalence of 0.5 %. The prevalence of CVD in male children (0.6%) was higher compared to female children (0.4 %). The mean age of patient with CVD and without CVD was 12.23 and 12.6 whose p-value was 1.28 which indicates no significant difference in the age group of both the category. The mean V/A LogMAR of the children with CVD was normal compared to the children without CVD. There was no correlation of children of CVD with Refractive error, Amblyopia, Strabismus and Anisometropia. Conclusion: - In our study we concluded that the colour blindness mostly affects boys but it can affect both the gender. Red and green deficiency is most common because of its genetic heritance. Along with it, there was no relationship between CVD and type of Amblyopia, Refractive error, Anisometropia or Strabismus.
