Ocular Manifestations of Pituitary Adenomas

Abstract

Fifty patients with pituitary adenomas were evaluated preoperatively by an ophthalmologist; of these, 68% had visual field defects, the most common (25%) a superior bitemporal depression and 16%, bitemporal hemianopsia. Almost 60% of patients with field defects had visual complaints; 38% had visual acuity in one eye of 20/60 or less. Patients with larger, nonsecreting tumors had more visual defects than patients with secreting pituitary adenomas.
