Blue Vision (Cyanopsia) Associated With TURP Syndrome: A Case Report

A A Pract. 2018 Nov 15;11(10):279-281. doi: 10.1213/XAA.0000000000000809.


There have been many complications associated with transurethral resection of the prostate (TURP), known as TURP syndrome. Of the various irrigation fluids used for TURP, glycine irrigant has been historically popular given its relatively low cost. It is also a nonconductive solution and only slightly hypoosmolar, reducing the risk of burn injury or significant hemolysis. However, there have been many case reports of central nervous system toxicity such as transient blindness and encephalopathy related to glycine toxicity. Here, we report blue vision (cyanopsia), which has never been reported as a symptom of TURP syndrome.
