Abstract

Melanocytoma of the Optic nerve head, is a benign, stationary pigmented tumor present on or adjacent to the optic disc. Rarely it exhibits minor enlargement and can also undergo malignant transformation to a melanoma. Histopathologically a melanocytoma consists of intensely pigmented round to oval nevus cells with benign features. We report a case of a 77 year old lady with an Optic nerve head melanoma. The clinical features and the imaging characteristics including Ultrasound, Fluorescein angiography and Magnetic resonance imaging are presented.
