In this analytical study in 2006, two hundred sixty (260) students attending in four schools for blinds in Mashad, were examined by using the modified WHO/PBL Eye Examination Record, for children with blindness and low vision protocol. The anatomical abnormality and underlying etiology for each eye were recorded. Results
The mean age was 14/2±4/2 years. Hundred fifty seven (54/9%) were males and 129 (45/1%) were females. The major anatomical site of visual loss was retina (28/6%), followed by optic nerve atrophy, congenital cataract, corneal opacity, congenital glaucoma, albinism and whole globe problems. The most common type of eye surgery was cataract. The difference between men and women and the distribution of no light Perception (NLP), was statistically significant (P<0.01).Conclusion
