Abstract

Introduction : Optic disc melanocytoma is a deeply pigmented variant of melanocytic nevus, classically occurs in the optic disc.

Methodology: 51 year old male presented with redness of LE since 5 days. On examination his best corrected visual acuity was 20/20. Anterior segment of right eye was normal. Left eye showed features of anterior uveitis. Pupillary examination was within normal limits. Fundoscopy of right eye showed elevated uniformly deep pigmented lesion involving lower one third of disc with slight involvement of surrounding retina vitreous and macula was normal, left eye was normal

Results : A diagnosis of optic disc melanocytoma made based on the appearance. Patient was advised to undergo visual fields .

Conclusion : when compared to malignant melanoma, melanocytoma grows slowly over a period of time or remain stable. Rarely can cause visual loss due to optic neuropathy or retinal vascular obstruction. Serial fundus photography needed to rule out malignant transformation.
