Pituitary Adenomas are common benign Intracranial tumours which cause visual field defects by anterior visual pathway compression after suprasellar extension of pituitary macroadenomas. After fulfilling the inclusion criteria, 31 patients with pituitary macroadenomas were evaluated for visual field defects using Humphrey Visual filed analyser (Perimeter). Thirteen patients had normal visual fields and 18 patients had abnormal visual fields. Bitemporal hemianopia was the most common visual field defect seen on perimetry. Also there was a positive correlation between the tumour size and the visual field defects.
