====== Pregeniculate blindness ======

Elevated [[ICP]] transmits pressure to [[retina]] → [[blood flow]] stasis, as well as mechanical trauma to optic chiasm from enlarging [[third ventricle]] (latter more commonly thought to be responsible for [[bitemporal hemianopia]], but could, if unchecked, progress to complete [[visual loss]]). Also, if [[hypotension]] and [[anemia]] were present, consider the possibility of [[ischemic optic neuropathy]], which may be anterior, or posterior (the latter of which carries a poorer prognosis).
