Unilateral congenital glaucoma in a child with optic nerve aplasia.

Unilateral optic nerve aplasia is a rare, nonhereditary defect associated with anterior chamber malformations and other ocular malformations. We report the case of an 8½-week-old boy with unilateral optic nerve aplasia who was diagnosed with glaucoma on presentation with corneal edema and an intraocular pressure of 36 mm Hg. The cornea edema cleared after a trabeculotomy, and subsequent fundus examination revealed optic nerve aplasia that was confirmed with magnetic resonance imaging. Intraocular pressure remained well-controlled with 7½ months of follow-up. To our knowledge, this is the first documented case of optic nerve aplasia associated with glaucoma at presentation.
