Visual Field Analysis of 371 Cases with Pituitary Adenoma

Abstract

Pituitary adenoma (PA) is one of the most common tumors occurring in the sella turcica. It mainly arises from the anterior lobe of the pituitary gland (adenohypophysis). The pituitary adenoma arising from neurohypophysis is rare. Patients with pituitary adenoma may present with symptoms of endocrine dysfunction or with neurologic space-occupying symptoms. Some patients initially go to the Department of Ophthalmology due to decreased vision and visual field defects caused by the optic chiasm compression [1].
