Sturge–Weber syndrome

A rare, congenital condition that affects the skin and the brain. Characteristically, a large purple birthmark (port wine stain) extends over one side of the face, including the eye. Malformation of cerebral blood vessels may cause weakness on one side of the body, progressive mental handicap, and epilepsy. Glaucoma may develop in the affected eye, leading to loss of vision. Seizures can usually be controlled with anticonvulsant drugs. In severe cases, brain surgery may be necessary.
