Abstract
Background: Colour vision deficiency is the commonest disorder of the eye that can be congenital or acquired. The colour vision disorders are usually undiagnosed due to unawareness of the disease, lack of screening, and adaptation by patients to environment to some extent.
Objectives: To find out the prevalence and pattern of colour vision defect among school students of ages nine years to 18 years in Bhaktapur municipality, Nepal.
Methods: This community-based, analytical, cross-sectional study done was among 1140 school students of Bhaktapur municipality of ages nine years to 18 years. Data collection was done from 2021 October to 2021 December utilising random sampling. The ethical clearance was obtained from Institutional Review Committee of Tilganga Institute of Ophthalmology. Assent and informed consent were obtained before data collection. Descriptive statistics such as mean, standard deviation, frequency, and percent were calculated.
Results: In total 596 (52.2%) were male students and 544 (47.7%) were female with the mean age of distribution 13.7±3.2 years. The prevalence of colour vision defect obtained was 3.6% in 41 cases, among 29 (4.8%) male and 12 (2.2%) female. Of the total colour vision defects, 19 (46.3%) were deuteroanomaly, 12 (29.2%) deuteroanopia, and 10 (24.4%) were protanomaly.
Conclusion: This study concludes that the prevalence of colour vision defect is significant. Early detection at school level helps to meet up with one’s potential build up in respective field and in counselling to step down from choosing certain profession in future.
