Treatment of Postfiltration Bleb Leak by Bleb Injection of Autologous Blood

Abstract

We treated a persistent, brisk bleb-leak after trabeculectomy with mitomycin C by bleb injection of autologous blood. Following preparation with povidone iodine, approximately 0.5 cc of whole autologous blood was injected into the bleb at the slit lamp. The leak resolved after 36 hours, and after 9 months' follow up, continued to function well.
