    Description
    A 21-year-old Indian male presented with incidentally discovered subnormal vision in the left eye. On examination, he had esotropia with high myopia of -14 dioptres. Fundus examination revealed extensively myelinated nerve fibres around the optic disc extending along the arcade but sparing the fovea. The association of myelinated nerve fibres with high myopia and amblyopia is well documented but the causal association between these is unproven. Early detection of refractive error and aggressive therapy to prevent amblyopia has been reported with some success.
