    This is a fundus picture of a young 42-year male who visited for a routine eye exam. His BCVA was 20/20 in both eyes. Anterior segment examination was normal. His left eye showed grey-black pigmentation at the infero-nasal margin of the optic disc. Fundus of the right eye was normal. The patient was diagnosed to have optic disc melanocytoma on multimodal imaging and was advised regular follow-up. Optic nerve melanocytoma is typically a benign tumor made up of melanocytes and melanin. It can grow, but rarely transforms into a malignancy. Patients with Optic Nerve Melanocytoma should be periodically examined for evidence of growth, loss of visual field and optic nerve compression.
