A 25-year-old male presented with sudden onset painless diminution of vision in the right eye of 1-week duration. Best-corrected visual acuity in the right eye was 20/200N 12; the left eye was 20/20N6; Normal color vision in left eye. Anterior segment was normal in both eyes except for relative afferent pupillary defect in the right eye. Left eye fundus was normal [Figure 1]b. Fundus of the right eye showed a blackish pigmented lesion on the surface of the disc obscuring the details of the disc and the cup engulfing a small portion of the inferior retinal vein [Figure 1]a. Vessels were faintly seen through the lesion. The rest of the optic disc appeared edematous with blurred disc margins. Faint superficial flame-shaped hemorrhage noted along the inferior margin of the optic disc. Peripapillary edema with macular edema noted with the rest of the retinal background and peripheral retina appeared normal. Fundus Fluorescein angiography showed blocked fluorescence and superior disc leak [Figure 1]c. Diagnosis of optic disc melanocytoma with optic neuritis was made. The patient was treated with oral steroids (1 mg/kg body weight), tapered over the next 3 weeks. Vision improved significantly to 20/20 in the first week with the formation of a macular star and resolution of macular edema [Figure 1]d and [Figure 2]b. Differentials of ischemic optic neuropathy, central serous retinopathy, malignant transformation of optic disc melanocytoma, malignant melanoma should also be ruled out.

| Discussion|| |
Optic disc melanocytoma is characteristically dark brown to black colored benign lesions usually located on the optic nerve head, largely asymptomatic discovered only on routine ophthalmic evaluation with small possibility of lesion turning malignant., Common complications associated are retinal vein obstruction, optic nerve infiltration, tumor enlargement or necrosis, visual field defects, and choroidal neovascular membranes.
Ischemic necrosis of the melanocytoma in the postlaminar region, causing cytokine-mediated inflammation of the optic nerve and neuroretinitis is the possible hypothesis., Previous reports suggested delayed and incomplete visual recovery unlike in our case which showed dramatic and faster recovery probably due to steroid therapy.
