Visual Field Loss due to Cystic Compression of Pituitary Gland Tumor

Abstract

Introduction

Pituitary adenomas are the most common cause of optic chiasm compression in adults. These tumors are classified by their size to Microadenomas: <10 mm and Macroadenomas: ≥10 mm which is diagnosed by CT or MRI. Peripheral vision loss, blurry vision, diplopia, headache and dizziness are the usual symptoms of pituitary tumor. We are presenting a patient with peripheral vision loss and optic nerve damage from cystic compression of pituitary macroadenoma.
