An eye was considered to have corneal blindness if the visual acuity was Main Outcome Measures The main outcome measure was prevalence rates of corneal blindness and low vision. Results Among the 10 384 people enrolled in the study, the prevalence of corneal blindness is 0.3% (95% confidence interval 0.2-0.4%). The leading cause was keratitis in childhood (40.0%), followed by ocular trauma (33.3%) and keratitis in adulthood (20.0%).
