Anticoagulation therapy in glaucoma surgery.

摘要

PURPOSE: To identify the practices of ophthalmologists when undertaking glaucoma surgery on patients concurrently using warfarin or acetylsalicylic acid (aspirin). METHODS: A questionnaire was designed to examine perioperative management of patients being treated with warfarin and aspirin prior to and during glaucoma surgery. The questionnaire was posted with stamped self-addressed envelopes to all glaucoma specialists registered on a glaucoma shared care scheme database. RESULTS: Of the 93 eligible participants, 64 returned a completed questionnaire, representing a response rate of 68.8%. Twenty-one surgeons (32.8%) routinely stopped warfarin before surgery. Mean time prior to surgery of drug cessation was 4 days (range 2-7). Three surgeons (14.3%) routinely commenced heparin if they stopped warfarin. Ten (47.6%) never used heparin, while the remaining eight (38.1%) would use heparin depending upon the indication for anticoagulation. Forty-two surgeons (81.25%)were happy to operate only at an INR
