A survey of hereditary colour vision defect in Ghanaian students

Abstract

The colour vision of 2,524 Ghanaian students made up of 1296 female and 1228 males were assessed in a cross-sectional survey, Eighty-seven students had hereditary colour vision defects. Red-Green defect accounted for 83 out of 87 of the colour blindness detected made up of 74 /1228 (6.02%) of the male and 9/1296 (0.69%) of the female population. The prevalence of red-green colour blindness IS significantly higher in males than females. We think it will be helpful and worth screening male students for colour vision defects to create awareness among parents, students and teachers and guide career planning.
