Progress in opthalmic exanination and functional magnetic resonance imaging in pituitary adenoma / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

Pituitary adenoma, the most common benign tumor in brain, its symptoms mainly include impaired visual function and endocrine hormone disorder. Visual acuity decline and visual field defect are the first symptoms, because of the special position of pituitary and optic chiasma, patients are often first seen in the ophthalmology department. Visual field examination and optical coherence tomography(OCT)can determine the degree of visual field defect and fundus condition. Electrophysiology examination can determine whether the optic nerve is damaged. All of them can be used as evaluation indexes of visual function in patients with pituitary adenoma. As an imaging tool, functional magnetic resonance, a derivative technique, has been used to study the texture of pituitary adenoma and optic nerve integrity in recent years. These comprehensive and detailed examinations can determine the best time for treatment and improve quality of life for patients. This article reviews the application of ophthalmic examination(visual field, OCT and electrophysiology)and functional magnetic resonance in pituitary adenoma.
