Congenital Cyst of the Optic Nerve: A Case Series

Abstract

Congenital cyst of the optic nerve is a rare congenital anomaly, scarcely reported. We report a large case series from a single institute over a period of 21 years, consisting of 3cases with rare presentations. Retrospective study of 1100 orbital cases revealed three cases with congenital cyst of optic nerve reported here. In these patients, a cyst was replacing almost all of the intraorbital portion of the optic nerve, with their unique features. Management of the cases is also discussed.
