Optical coherence tomography study of optic disc melanocytoma.
Optic disc melanocytoma is a well-known clinical entity occurring as a deeply pigmented lesion on the optic nerve head. A 40-year-old man with a pigmented lesion overlying the left optic disc was evaluated with optical coherence tomography. The single high reflectance band from the anterior edge of the disc lesion with optical back shadowing behind on optical coherence tomography helped to pinpoint the diagnosis of the lesion as optic disc melanocytoma. Quantitative assessment of the mass with optical coherence tomography for its growth did not show any increase in size horizontally or vertically after 6 months. Optical coherence tomography is useful for obtaining the exact measurements of the mass lesion and may be used as a tool to follow the progress and growth pattern of the lesion.
