title: [Myelinated nerve fibers associated with cilioretinal artery occlusion].
abstract: Although the myelinated nerve fibers are considered as benign, cases associated with retinal vascular abnormalities (telangiectasis, neovascularization, vascular occlusions) have recently been reported, suggesting a possible pathogenic correlation between these elements. Our observation presents a 44-year-old patient, with a sudden decrease of visual acuity in the right eye, discal and peridiscal myelinated nerve fibers, associated with cilioretinal artery occlusion. The general clinical and laboratory examination, except for a drug stabilized arterial hypertension, did not reveal other local or general embolic factors. One year later, the decrease in visual acuity had remained unchanged and the area of the myelinated nerve fibers had diminished. Based on the association between the myelinated nerve fibers, the cilioretinal artery occlusion, the young age of the patient, and the absence of other local or general embolic factors, we consider there is a possible pathogenic correlation between these elements. The action of the myelinated nerve fibers can be explained by a mechanical compression, with the disruption of the cilioretinal artery route, a structurally vulnerable artery.
