Photodynamic therapy in von Hippel-Lindau disease in children.

Von Hippel-Lindau disease is characterized by retinal hemangiomas that often produce hemorrhages and retinal detachment. A 10-year-old boy with von Hippel-Lindau disease presenting with telangiectasias, endophytic angiomas, and exudative retinal detachment underwent treatment with retrobulbar steroid injection, laser photocoagulation, and photodynamic therapy, which led to improvement of visual acuity.
