Peripheral retinal neovascularization (Eales disease) associated with the factor V Leiden mutation.

Abstract

To illustrate a case of peripheral retinal neovascularization (Eales disease) in a patient who tested positive for the factor V Leiden mutation. A 42-year-old woman had a 1-week history of blurred vision in her right eye. Her medical history was remarkable for a cerebrovascular accident. Ophthalmoscopy of the right eye disclosed a mild vitreous hemorrhage and a ridge of retinal neovascularization in the temporal periphery. The left fundus showed evidence of temporal retinal ischemia. A laboratory evaluation for hypercoagulability was positive for factor V Leiden mutation. Peripheral scatter laser photocoagulation was applied to the ischemic retina, and the neovascularization regressed. The patient began taking warfarin sodium to prevent further thrombotic events. A laboratory evaluation for coagulopathy, including the factor V Leiden mutation, should be added to the examination of patients with Eales disease, especially individuals with a history of a previous thrombotic event.
