Progression of myelinated retinal nerve fibers.

Abstract

To present a case demonstrating progression of retinal nerve fiber myelin and to suggest that myelinated retinal nerve fibers be considered among the peripapillary choristomas. Case report. A 46-year-old woman demonstrated progression of myelinated retinal nerve fibers and associated retinal vascular anomalies. Myelinated retinal nerve fibers can be progressive. We confirm earlier reports of vascular anomalies associated with retinal nerve fiber myelin and show that they can also be progressive. The rarely progressive nature of myelinated retinal nerve fibers and the histopathologic studies published to date suggest that myelinated retinal nerve fibers represent a striking ophthalmoscopic feature resulting from ectopic oligodendrocytes; thus, the entity may be described as an oligodendrocytic choristoma.
