Of 23 cases with cysticercal visual loss, 13 had optic neuropathy (due largely to papilledema), 4 sustained chiasmal damage, and 6 had retrochiasmal lesions. Papilledema usually was associated with hydrocephalus, chiasmal involvement was ca used by inflammation and compression from adjacent cysts, and retrochiasmal damage was produced by large parenchymal cysts or vasculitic cerebral infarction. |
