Aims: To determine the causes of blindness and major anatomical site of lesion leading to blindness in schools for blind in Southern Rajasthan. 
Study Design: Survey based observational study.

Methods: All the students (114) of blind schools were included in study. All data were recorded using a modified World Heath Organization Prevention of Blindness (WHO/PBL) eye examination record for children, including the anatomical and aetiogical classification. This was used to categorize the causes of blindness and to record the findings using the definitions in the coding instructions.

Statistical analysis used: The data were entered into a database and analyzed using SPSS version 21 for Windows.

Results: Whole globe was affected in majority of the students (36.9%) which led to blindness, followed by uvea (15.8%), lens (14.9%), cornea (14%), optic nerve (9.6%), and retina (8.8%). In majority of students exact aetiology which led to blindness could not be determined (62.3%). 14% students had hereditary factors, 2.6% had neonatal factors and 21.1% had childhood factors which led to vision loss.

Conclusions: 52.7% students had avoidable cause of blindness. 33.4% students had preventable causes and 19.3% students had treatable causes. Childhood factors have become increasingly significant as causes of visual loss in children who became blind after the year 2000.
