Description
Summary:Color vision defect can be observed in various diseases of optic nerve and retina and also a significant number of people suffer from the inherited condition of red and green color defect. A cross-sectional descriptive study was designed with purposive sampling of students from various schools of Kathmandu Valley. All children were subjected to color vision evaluation using Ishihara Isochromatic color plates along with other examination to rule out any other causes for color deficiency. A total of 2001 students were examined, 1050 male students and 951 females with mean age of 10.35 (+/- 2.75) and 10.54 (+/- 2.72) respectively. Among the total students examined, 2.1% had some form of color vision defects. Of the male population, 3.9% had color vision defects while none of the female was found with the deficiency. The prevalence of color vision defect in Nepal is significant and comparable with the prevalence quoted in studies from different countries.
