Myelinated Nerve Fibers
Nerve fibers in the retina, which are covered with patches of a fat like substance (arrows) called myelin. This condition is congenital and rarely causes loss of vision or requires treatment.

Myelinated retinal nerve fiber layers (RNFLs) are relatively common and generally benign. They appear as white, sharply demarcated patches on the surface of the retina that obscure the underlying retinal vessels.

Myelinated nerve fibers (MNF) occur in less than 1% of the population. However, they might be responsible for diagnostic dilemmas in cases with visual loss.

Patients with extensive myelination may have an increased incidence of myopia, amblyopia and strabismus.
