- Abstract
Background and Objective: Previous literature assessing ocular hemorrhagic complications of anticoagulant/antiplatelet medications in routine clinical practice is limited. This study evaluates the prevalence of spontaneous ocular hemorrhagic events associated with anticoagulation/antiplatelet therapy., Patients and Methods: A retrospective study was performed to identify patients taking anticoagulants (rivaroxaban [Xarelto; Janssen Pharmaceuticals, Beerse, Belgium], bivalirudin [Angiomax; The Medicines Company, Parsippany, NJ], lepirudin [Refludan; Bayer HealthCare Pharmaceuticals, Berlin, Germany], dabigatran [Pradaxa; Boehringer Ingelheim, Ingelheim am Rhein, Germany], and argatroban) and antiplatelet agents (clopidogrel [Plavix; Bristol-Myers Squibb, New York City, NY], prasugrel [Effient; Lilly Medical, Indianapolis, IN], and ticagrelor [Brilinta; AstraZeneca, Cambridge, UK]) who presented for an eye examination. Location of hemorrhage, relevant systemic and ocular comorbidities, baseline demographics, and concomitant aspirin use were noted., Results: A total of 44 patients with spontaneous ocular hemorrhage were identified. Thirty patients had a single episode, whereas 14 patients had multiple episodes (two or more hemorrhagic events). Prevalence of spontaneous ocular hemorrhage on prasugrel (7.2%) and rivaroxaban (3.1%) was higher compared to dabigatran (1.9%), clopidogrel (2.0%), and ticagrelor (2.7%)., Conclusion: Prevalence of spontaneous ocular hemorrhage with use of anticoagulant/antiplatelet agents is higher in routine clinical practice as compared to previously reported literature.
