Optical Coherence Tomography Angiography Features in Melanocytoma of the Optic Nerve
Abstract:
Optic disc melanocytoma (ODM) is a pigmented tumor with malignant potential characterized clinically as a dark brown to black lesion with feathery margins. The authors report a case of ODM and describe the utility of optical coherence tomography angiography (OCTA) in detecting superficial tumor vascularization. This case report demonstrated the ability of OCTA to reveal the fine abnormal retinal vasculature on the surface of the lesion, a characteristic of ODM, which has been previously correlated with tumor growth. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:364-366.].
