The authors present the multimodal imaging findings of an unusual case of bilateral acquired progressive myelination of the optic disc during a 10-year follow-up period in a hyperopic adolescent patient in the absence of an underlying ocular or systemic abnormality. Myelination of the left optic disc was noted at age 7 and of the right optic disc at age 13, but no other ocular or systemic abnormalities were identified. Cross-sectional optical coherence tomography (OCT) and en face OCT angiography confirmed the presence of myelination of the retinal nerve fiber layer and excluded other etiologic possibilities including an astrocytic hamartoma.
