The TUR syndrome is a clinical disorder consisting of circulatory, gas
trointestinal, and neurologic signs that are infrequently seen in some
patients undergoing endoscopic surgery of the prostate gland with the
use of nonconductive irrigating fluids. Several theories of its patho
genesis have been proposed. The condition may occasionally be associat
ed with bilateral profound loss of vision. We report a patient with th
e TUR syndrome who suffered bilateral temporary blindness and speculat
e on the etiology of the visual loss and localization of the dysfuncti
on along the visual pathway.
