Özet

Background: Blindness or visual deterioration after neck dissection is a known and a rare complication of the operation. Visual impairment usually occurs immediately after bilateral radical neck dissections either performed synchronously or in a stepwise manner, resulting in permanent blindness. Hypotension and blood loss during long operations, elevated venous pressure postoperatively result in optic neuropathics, which are anterior ischemic optic neuropathy (AION) or mostly posterior ischemic optic neuropathy (PION) affecting different portions of the nerve.
