Open-angle glaucoma and paraoptic cyst: First description of a series of 11 patients

Abstract

We report 11 patients who were referred to our institution for severe open-angle glaucoma who had a paraoptic cyst on MR imaging.

Arterial vascularization of the optic nerve was normal. Cyst volumes were inversely correlated with the severity of glaucoma on the same eye (P
