Rhegmatogenous retinal detachment in Wyburn-Mason syndrome: case report

Wyburn-Mason is a rare vascular disorder, comprised of arteriovenous malformations (AVMs) of the midbrain and retina. It can cause visual symptoms depending on its localization and extension. Vitreous and intraretinal hemorrhage and neovascular glaucoma have been previously described. A case of rhegmatogenous retinal detachment in a patient with Wyburn-Mason syndrome is described. A 27 year-old woman previously diagnosed with Wyburn-Mason syndrome, sought attendance with sudden low vision in right eye 3 months before. She presented moderate vitreous hemorrhage and retinal detachment with a superior tear. She underwent a successful posterior vitrectomy with implantation of silicone oil, with reattachment of the retina. Rhegmatogenous retinal detachment in a patient with Wyburn-Mason syndrome has been not previously described in the literature. Vitrectomy in this case present challenges related to intraoperatory bleeding risk, to a posterior pole tear among AVMs and the difficulty of obtaining free retina for photocoagulation.
