Optic Disc Melanocytoma; A Rare Entity.

A young male presented with complaints of disturbance of vision and floaters for the past five years with best corrected visual acuity of 6/6 in both eyes. Ophthalmic examination of the anterior segment was normal in both eyes. There was a relative afferent papillary defect in the right eye. Fundoscopic examination of the left eye showed a raised, 3-disc diameter (DD) dark brown lesion arising from the optic disc. Ophthalmic investigations were performed including fundus photos, A-scan, B-scan, Auto-fluorescence, OCT, and FFA. Findings were consistent with those of optic disc melanocytoma. The patient is now kept on close three-monthly follow-up. To the best of our knowledge, there are no published reports from Pakistan so far.
