Melanocytoma of the optic disc associated with visual field defects: clinical features and imaging characteristics.

The authors studied the clinical features, visual field, and spectral-domain optical coherence tomography (SD-OCT) characteristics of peripapillary melanocytoma associated with visual field defects in two eyes of two patients. Both eyes had hyperreflective anterior surface and posterior optical shadowing in the region of peripapillary melanocytoma on SD-OCT imaging. The retinal nerve fiber layer was thin adjacent to these lesions, and this corresponded to the opposite hemifield defect on Humphrey Visual Field testing. Three-dimensional imaging of the melanocytoma revealed an irregular elevation in the peripapillary region. SD-OCT, when used in conjunction with clinical examination and Humphrey Visual Field testing, provided useful information that may assist clinicians in treating patients with peripapillary melanocytoma, particularly when observing them over time.
