Myelinated
retinal nerve fibers (MRNFs) are developmental anomalies of the retina that
appear as white to grey-white striated patches with feathery edges, often
distributed around or contiguous with the optic disc and surrounding the
vascular arcades. Based on a fundus photography study including 5789 patients,
Kodama et al. reported that MRNFs occur in approximately 0.57% of the
population, most often involving superior and inferior-temporal per papillary
areas. No MRNFs were discovered in the macula, and 7.7% were bilateral.
