Multimodal imaging assessment of a "micro" optic disk melanocytoma: A case report. / Evaluación multimodal de un «micromelanocitoma¼ del disco óptico: un reporte de caso.

ABSTRACT

An optic disk melanocytoma is a benign pigmented neoplasm of the optic disk measuring 2.00mm of diameter in average. Smaller optic disk melanocytomas are rare and have not been studied with multiple imaging studies. A case of a "micro" optic disk melanocytoma measuring 0.71mm in diameter was studied by multiple imaging modalities, including fundus autofluorescence, ultrasound, visual fields, optical coherence tomography (OCT) and OCT angiography. While clinical appreciation and fundus autofluorescence reveal changes compatible with previously reported cases, OCT, OCT angiography and ultrasound reveal specific changes that could be useful for follow up.
