A 79-year-old woman was referred for rapid onset of painless bilateral vision loss. Anterior segment exams revealed bilateral spontaneous hyphema and fibrin accumulation. Observation of the posterior chamber by B-scan ultrasound showed vitreous hemorrhage and choroidal detachment bilaterally. No evidence of additional intraocular inflammation was present. Laboratory work-up for hematologic abnormalities was unremarkable. These hemorrhagic events were suspected to be a complication from taking the novel anticoagulant, dabigatran etexilate (Pradaxa; Boehringer, Ingelheim, Germany). She initially underwent non-surgical therapy, which included immediate cessation of dabigatran, and administration of topical and systemic steroids. The lack of response to medical therapy in the left eye led to surgical treatment of vitreous and persistent subcapsular hemorrhage via pars planar vitrectomy with capsulectomy.
