Good visual function in posterior microphthalmos.
Posterior microphthalmos is a rare condition in which the anterior segment is normal in size and configuration, but the posterior segment is reduced in size; this results in axial hyperopia and retinal folding. Patients have decreased vision that is caused by posterior segment abnormalities, high refractive error, and amblyopia. We present a case of posterior microphthalmos in which retinal function was relatively intact and visual loss was believed to be primarily caused by refractive error and amblyopia. After treatment, the child's visual acuity and school performance improved. This case emphasizes the need for careful examination, refraction, and follow-up for these children because their visual potential may be reasonably good.
