I was wondering what are the causes of bitemporal hemianopia?

Causes of bitemporal: Hemianopsia include pituitary lesions which can put pressure on the optic chiasm. These lesions include adenomas, meningiomas, craniopharyngiomas, sarcoidosis, primitive neuroectodermal tumors (pnet), aneursymal enlargement of the anterior communicating artery, and sphenoid sinus destructive lesions with extension. I hope this helps. Well wishes.
