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.
