Myelinated nerve fibers and severe myopia.
نویسندگان
چکیده
Two 4-year-old boys, one white and one black, had unilateral extensive myelinization of retinal nerve fibers associated with severe myopia, esotropia, and amblyopia. The finding of unilateral extensive myelinization of the nerve head and retinal fibers in a child may indicate a potentially remediable anisometropic amblyopia.

Unilateral Myelinated Retinal Nerve Fibers
87 Dear Editor, I read the photo essay titled “Unilateral Myelinated Retinal Nerve Fibers” with interest.[1] The authors reported a case of unilateral extensive myelination with amblyopia, with partial improvement after occlusion therapy. However, there was no comment about the status of the optic nerve head. Several reports have suggested that myelinated nerve fibers are associated with optic ...
متن کاملAssociation of extensive myelinated nerve fibers and high degree myopia: Case report
Unilateral extensive myelination of the peripapillary nerve fibers may be associated with anisometropic myopia, strabismus, and reduced vision. Myelination of optic nerve fibers terminate at lamina cribrosa. Yet in some patients, myelination progresses into the peripapillary retinal nerve fibers and may affect the visual acuity. In this report, we described 4 patients. All patients presented ex...

This report describes a case of unilateral myelinated retinal nerve fibers associated with ipsilateral myopia and amblyopia. A 9-year-old girl presented with the complaint of diminished vision in her left eye for several years. Her bestcorrected visual acuity was 1.2 in the right eye and 0.06 in the left eye. The refractive error was -0.25D and -4.00D in the right and left eyes, respectively. F...

tion of retinal fibers leads to myopia or myopia leads to myelination of retinal fibers. Alternatively, myopia and retinal myelination may be associated with other factors. Schmidt et al proposed that myelinated fibers could blur retinal images and induce visual deprivation. Such deprivation at a critical stage of ocular development could lead to axial elongation, akin to structural changes see...
متن کاملUnilateral myelinated retinal nerve fibers associated with ipsilateral myopia and amblyopia
The objective is to evaluate the clinical features of unilateral myelinated retinal nerve fibers (MRNF) associated with ipsilateral myopia and amblyopia. We retrospectively analyzed three patients with unilateral MRNF associated with ipsilateral myopia and amblyopia. The ages at presentation range from 4 to 10 years. Refractive error in affected eye ranged from S-6.25DC-2.00D toS-9.75DC-1.25D40...
