WebDarin R. Goldman, in Atlas of Retinal OCT: Optical Coherence Tomography, 2024 Summary. Myelinated nerve fiber layer (mNFL) is a benign clinical entity that results from an embryologic developmental anomaly whereby focal areas of the retinal nerve fiber layer fail to lose their myelin sheath. Clinically, mNFL appears as distinct white patches on the … WebMost nerve fibers inside and outside the brain are wrapped with many layers of tissue composed of a fat (lipoprotein) called myelin. These layers form the myelin sheath. Much like the insulation around an electrical wire, the myelin sheath enables nerve signals (electrical impulses) to be conducted along the nerve fiber with speed and accuracy.
