Loss of vision: a manifestation of TURP syndrome. A case report.

: We report a case of transient blindness, part of a TURP syndrome, in a 65 year old man undergoing TUR of the prostate under centro-neuron block. Irrigating fluid consisted of 1.5% glycine. As a result, serum levels of glycine increased to 12,470 mols.l-1 (N176-332 mumols.l-1). We attribute this loss of vision to glycine toxicity.
