Title: Prevalence of the optic disc anomalies in the adult South Indian population
Abstract: To determine the prevalence of congenitally abnormal disc (all anomalies) in an adult population in southern India.Subjects aged ≥40 years (n=6013) underwent a complete ophthalmic examination. Optic disc anomalies were diagnosed according to the definitions given in the article.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%).The prevalence of optic disc anomalies is 1.1% in the adult South Indian population.
