Prevalence of the optic disc anomalies in the adult South Indian population


Purpose To determine the prevalence of congenitally abnormal disc (all anomalies) in an adult population in southern India.

Methods Subjects aged ≥40 years (n=6013) underwent a complete ophthalmic examination. Optic disc anomalies were diagnosed according to the definitions given in the article.

Results Optic disc anomalies were found in 81 eyes of 66 (1.1%, 95% CIs 0.00834 to 0.01361) patients. The prevalence of each anomaly in the descending order was peripapillary myelinated nerve fibre (0.28%), epipapillary glial tissue on the optic disc (0.28%), peripapillary vascular loops (0.16%), tilted disc (0.09%), optic disc coloboma (0.08%), optic nerve hypoplasia (0.04%), optic disc pit (0.04%), optic disc pigmentation (0.03%), optic nerve head drusen (0.03%), Bergmeister’s papilla (0.03%), optic disc pit and coloboma (0.01%).

Conclusions The prevalence of optic disc anomalies is 1.1% in the adult South Indian population.
