Hemifield Slide Phenomenon from Pituitary Macroadenoma

Abstract

Pituitary apoplexy (PA) is a rare endocrine emergency, which can occur due to acute hemorrhage or infarction of pituitary gland, usually in the context of a pituitary macroadenoma. The most frequent ophthalmologic symptoms/sings are impaired visual acuity, visual field defects, and diplopia. A dense bitemporal hemianopic scotoma can cause a rare non-paretic diplopia, so-called hemifield slide phenomenon. This brief report describes a patient with this phenomenon caused by a PA from a pituitary macroadenoma.
