Definition

Bitemporal hemianopsia (BTH) is a form of visual field loss of the temporal half of the visual field in both eyes that generally respects the vertical midline. This type of vision loss results from disruption of the nasal crossing fibers of both eyes due to lesions at the optic chiasm. Bilateral retinal lesions in the nasal portion of the retina or tilted optic nerves may mimic a bitemporal hemianopsia from chiasmal lesions.

Etiology

A BTH is caused by a lesion at the optic chiasm. The most common chiasmal lesions in adults include pituitary adenoma, craniopharyngioma, meningioma, or suprasellar internal carotid artery aneurysm. In children, optic pathway glioma and dysgerminoma are more common than meningioma or aneurysm, but pituitary adenoma and craniopharyngioma remain in the differential diagnosis. Pituitary lesions arise from the pituitary gland in the sella turcica and then extend to the suprasellar space and thus compress the nasal crossing fibers in the chiasm from...
