Assessment of Colour Blindness and Erythrocyte G6PD Enzyme Status among the School Children of Dhaka City

Background: Visual impairment due to colour blindness is an unusual suffering of the school children. It may be associated with erythrocyte G6PD enzyme deficiency. Objective: To find out defective vision due to colour blindness in apparently healthy school children and to measure erythrocyte G6PD enzyme level among them. Methods: This cross sectional study was carried out in the Department of Physiology, SSMC from 1st July 2007 to 31st June 2008. Five hundred (500) apparently healthy school children of old Dhaka, age ranged from 6 to 12 years irrespective of gender and race was selected as study population.
