PURPOSE: The purpose of this retrospective study was to determine the extent to which the use of antithrombotic drugs during glaucoma surgery contributes to surgical failure and postsurgical hemorrhagic complications. METHODS: Glaucoma surgeries were categorized into three groups: trabeculotomy (TLO), trabeculectomy (TLE), and long-Tube shunt surgery (Tube). At 1 year after surgery, the following criteria for surgical success were met: intraocular pressure (IOP) in the 5-21-mmHg range, IOP reduction of at least 20% from the preoperative level, and no additional glaucoma surgeries. We compared the percentages of the success rates and hemorrhagic complications between antithrombotic medication experiencers and non-experiencers. Furthermore, we adjusted the preoperative factors between the two groups using a propensity score analysis in TLO and TLE surgeries. RESULTS: A total of 910 glaucoma surgeries were included, with TLO, TLE, and Tube accounting for 353, 444, and 113 surgeries, respectively. Preoperative antithrombotic medications were administered to 149 patients in all glaucoma surgeries: 37 patients used only anticoagulants, 102 used only antiplatelets, and 10 used both. There was no significant difference in the success rates of any of the procedures. The hemorrhagic complications (hyphema and vitreous hemorrhage rate) were significantly higher in the patients who underwent TLE and Tube. The surgical success rates of TLO and TLE were not significantly different after the two groups were matched by propensity score. CONCLUSION: The perioperative use of antithrombotic drugs did not affect success for any of the procedures. However, it increased early postoperative hemorrhagic complications for TLE and Tube.
