Myelinated Retinal Nerve Fibers, a Complicating Factor in Amblyopia Rehabilitation?

Abstract

Myelinated Retinal Nerve Fibers (MRNFs) can be observed on fundus photography. This has the appearance of white striated patches with poorly defined borders caused by a developmental error leading to myelination of retinal ganglion cell fibers by ectopic oligodendrocytes. The prevalence of MRNFs is low, ranging from 0.34% [1] to 0.98% [2], and there is no variation according to the origin or sex of the patients. Apart from associated pathologies, this type of fiber remains stable over time [2]. It is considered as a rare and mostly benign congenital anomaly. The objective is to show that in young children, the presence of extensive myelin fibers should be monitored more regularly by ophthalmologists.
