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).
