Extra-papillary Myelin Fiber of Incidental Finding: A Case Report

Abstract

We report an observation of an uncommon form of extra-papillary myelin fibers of fortuitous discovery in a patient, 55 years old, who consulted for a change of correction. The clinical aspect of the fundus led to the diagnosis of retinal myelin fibers in front of a whitish placard with a finely striated scalloped edge, partially masking the vessels and located at the level of the inferior temporal arch. These fibers, contiguous to the papilla or distant from it, have an incidence varying from 0.57% to 0.98% according to studies and their pathogenesis is still uncertain. This congenital anomaly of the retinal fibers of clinical diagnosis is often asymptomatic, but can however be associated with other ocular disorders.
