Medically reviewed by Dr. Alexander Bonakdar, O.D. · Updated February 2026

Wyburn-Mason Syndrome, also known as racemose hemangiomatosis or Bonnet-Dechaume-Blanc syndrome, is a rare congenital phakomatosis characterized by arteriovenous malformations (AVMs) affecting the retina, visual pathway, and brain (particularly the midbrain). Unlike other phakomatoses, it is not inherited. The retinal AVMs are direct artery-to-vein shunts without intervening capillaries, appearing as dramatically dilated, tortuous vessels.
