Superior segmental optic nerve hypoplasia: differential diagnosis with glaucoma

Abstract

Introduction:

Congenital changes of the optic nerve are rare. Hypoplasia is the most common form of congenital alteration of the optic nerve. It is believed to be correlated with interruption of fetal development and low birth weight. It presents as a non-progressive anomaly with generally preserved visual acuity. We related a case of a patient with superior segmental hypoplasia with ocular hypertension after corticosteroid use, with a decrease in the nerve fiber layer. Patients with hypoplasia should be followed more closely if they have risk factors for glaucoma and should be considered as a differential diagnosis for normal pressure glaucoma.
