This is to report the figures of survey of causes of blindness on 140,199 eye patients from various hospitals(total 19 in number) in Korea during 1970-1972.
Blindness is defined as visual acuity for distance of 0. 1(20/200) or less in better eye with best correction. Representation of diagnosis of ocular affection is based on examination of ophthalmo logists, and the Standard Classification of Causes of Blindness recommended by the International Association for the Prevention of Blindness(revised) is applied.
Estimated number of blindness is 2, 925(2. 09%). Proportion of blindness by causes indicates: Senile cataract(30. 03%), Systemic diseases(14.07%), Injury and intoxication(10.79%). Refractive errors(10.72%), and Infectious diseases(7. 58%), etc.
Rate of blindness by site and type of affection is shown as: Lens disorders(37.04%), Retinal diseases(10.84%), Optic nerve diseases(10.39%). Refractive errors(9.62%), Corneal diseases(9. 06 %) and Glaucoma(7.38%), etc.
