Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2019, Vol 8, Issue 12
Abstract
BACKGROUND Many people suffer from colour blindness but most of them remain undetected. Hence screening at the level of school going age leads to early detection and helps in guiding them in studies and professional choices. We wanted to find the prevalence of colour blindness in the age group of 11-15 years of school going children and to compare the prevalence rate between male and female students in Mandya district, Karnataka. MATERIALS AND METHODS A cross sectional observational study was done on 1571 students from four different schools of the same city to assess the prevalence of colour blindness. Students were examined with Ishihara Pseudoisochromatic Colour Plates 38th Edition. If the student was found to be colour blind, the student was further classified into different types of colour blindness. The data collected was then analysed to evaluate the prevalence of colour blindness, compare the prevalence between male and female students. RESULTS A total of 1571 students were evaluated from 4 different schools of the Mandya district among which 897 (57.09%) were males and 674 (42.90%) were female students who were in the age group between 11-15 years. The prevalence of colour blindness was found to be 1.4% (23 students out of 1571 students). Colour blindness was seen in 21 (1.3%) male students and 2 (0.1%) female students. Among the colour blind, 20 (1.2%) were protanopes, 3 (0.2%) were deuteranopes and none were tritanope. Males were affected more than female students. CONCLUSION Significant male population suffers from the congenital colour vision disorder. Those with congenital colour vision disorder should be properly examined early for colour vision disorder to rule out colour blindness in school children. Proper guidance can then be given to students about leaning pattern and even in finding an appropriate job/profession.
