determine the associations between the use of antithrombotic drugs and incident open-angle glaucoma (OAG).
examinations including measurements of the IOP and perimetry were performed at baseline and follow-up in 3939 participants of the prospective population-based Rotterdam Study who did not have OAG at baseline. The use of antithrombotic drugs was monitored continuously during follow-up. Antithrombotic drugs were stratified into anticoagulants and platelet aggregation inhibitors. Associations between incident OAG and the use of antithrombotic drugs were assessed using Cox regression; the model was adjusted for age, sex, baseline IOP and IOP-lowering treatment, family history of glaucoma, and myopia. Associations between antithrombotic drugs and IOP at follow-up were analyzed with multiple linear regression.
During a mean follow-up of 9.8 years, 108 participants (2.7%) developed OAG. The hazard ratio for anticoagulant use was 0.90 (95% confidence interval [CI], 0.55–1.48; P = 0.69) and for platelet aggregation inhibitors 0.80 (0.53–1.21; P = 0.28). There was no trend towards a reduced or increased risk of incident OAG with prolonged anticoagulant use (P value for trend 0.84) or platelet aggregation inhibitor use (0.59). There was a significant IOP-lowering effect of anticoagulants (−0.31 mm Hg; 95% CI, −0.58 to −0.04 mm Hg; P = 0.025) but not of platelet aggregation inhibitors (P = 0.06). The IOP-lowering effect of anticoagulants disappeared after additional adjustment for the use of systemic beta-blockers.
Use of anticoagulants or platelet aggregation inhibitors appears not to be associated with incident OAG.
