Vitreous Hemorrhage as Presenting Sign of Retinal Arteriovenous Malformation
Objective. To describe a patient with vitreous hemorrhage and peripheral retinal ischemia, eventually diagnosed with an underlying retinal arteriovenous malformation. Methods. A 15-year-old girl presented with sudden-onset, painless visual loss in the right eye. She underwent a full ophthalmological...

| description | Objective. To describe a patient with vitreous hemorrhage and peripheral retinal ischemia, eventually diagnosed with an underlying retinal arteriovenous malformation. Methods. A 15-year-old girl presented with sudden-onset, painless visual loss in the right eye. She underwent a full ophthalmological work-up. Results. BCVA was less than 20/400 in the right eye and 20/20 in the left eye. Intraocular pressure and anterior segment examination were unremarkable. Fundoscopy was impossible due to an opaque vitreous hemorrhage in the right eye. The left eye was completely unremarkable. Examination during a 23-gauge pars plana vitrectomy showed dilated, tortuous arteriovenous vessels extending from the optic disc and silver wiring of the enlarged vessels. A clinical diagnosis of retinal arteriovenous malformation was made. During surgery, a peripheral retinal photocoagulation was executed to avoid rebleeding. Postoperatively, fluorescein angiography demonstrated additional macular microangiopathy and diffuse retinal nonperfusion in the periphery. The MRI brain revealed neither cerebral nor orbital vascular anomaly, confirming a group 2 retinal arteriovenous malformation. Conclusion. Retinal arteriovenous malformations are generally considered stable over time. However, complications due to retinal ischemia can occur. Hence, regular observation is warranted. In so doing, timely treatment can be offered to avoid complications. |
