Superior segmental optic nerve hypoplasia with normotensive glaucoma: A case report

Abstract

We report a 27-year-old woman with a cup disk ratio of 0.75:1, with a focal superior neuroretinal rim loss and corresponding nerve fiber layer defect in both eyes. Intraocular pressure was 10 mm Hg in both eyes with normal anterior segment. Perimetry showed inferior arcuate defects in both eyes. A diagnosis of superior segmental optic nerve hypoplasia (SSOH) was made. On follow-up, there was progression in field defects, which were confirmed by repeat field tests, despite normal intraocular pressures. We concluded that there was coexisting normotensive glaucoma (NTG) in this patient.
