title: Familial unilateral Brown syndrome.
abstract: We present a two-generation family with Brown syndrome. The proband was a six and a half-year-old female who presented with a history of failure of dextro-elevation of her left eye. A full ophthalmic evaluation was consistent with a left Brown syndrome. Family history revealed that her mother was operated on as a child for left Brown syndrome and examination of her four and a half-year-old sibling showed similar affection in the left eye. Autosomal dominant inheritance has been postulated in this condition. To our knowledge this is the first report of three members of a two-generation family with left-sided Brown syndrome. Genetic counseling of Brown syndrome cases is advised; nevertheless, identification of the responsible gene should shed more light on its genetics.
