Optic nerve melanocytoma: pathophysiology, clinical considerations, and diagnostic novelties

Abstract

Optic nerve melanocytoma is a rare, benign, pigmented tumor of the optic disc that may cause visual complications in few cases and can be easily confused with a malignant melanoma. This review aims to highlight its clinical characteristics and pathophysiology, as well as to update the diagnostic methods available, like optical coherence tomography angiography.
