Ultrawide Field Imaging of Progressive Retinal Arteriovenous Malformation in a Pediatric Patient with Wyburn-Mason Syndrome.

Wyburn-Mason syndrome (WMS) is a rare congenital disease that presents with unilateral arteriovenous malformation (AVM) in the visual pathway, midbrain, and/or skin. We report a case of a 5-year-old girl with a history of cerebral and orbital AVM who presented with left exotropia and was found to have group 3 retinal AVM consistent with WMS. Here, we use ultrawide field imaging to show the progression of retinal AVM and peripheral nonperfusion areas for a period of 1 year in a pediatric patient with WMS. .
