dc.description.abstractBackground: Congenital color vision defect is one of the commonest genetic defects. It affects daily and professional living. Objective: This study was conducted to determine the prevalence of color vision defects among public secondary school students in Kosofe Local Government Area, of Lagos State with a view to providing data that could be useful for advocacy to institute regular school screening. Materials and Methods: A descriptive cross sectional study conducted among public school students in all the seven public secondary schools in Kosofe Local Government Area of Lagos State. Sample size was determined by Leslie-Kish formula. Students were selected using multistage sampling technique. Visual acuity was determined using the literate Snellen’s chart. Color vision status was screened using lshihara pseudo-isochromatic test and further categorization of degree of severity of color vision defects was determined using of Farnsworth- Munswell D-15. Results: Five hundred and forty students were examined with a mean age of 13.7+1.8 years (ranging 9-20years). There were 307 females and 233 males, with a female to male ratio of 1.3:1. The prevalence of color vision defects among respondents was 1.9% (10 students). There were 8 males and 2 females with color vision defects with a statistically significant difference between gender (p=0.02). There were 8 students with deuteranomaly and 2 students with protanoamaly but there was no tritan defect detected. Conclusion: The prevalence of color vision defect in this study is within the range of prevalence values reported in Nigeria. Color vision screening programs should be integrated into the pre-existing eye screening programs. Keywords: Color vision, defects, students, Nigeriaen_US
