Branch retinal artery occlusion in a young woman with Ménière's disease.

An unusual case of a 32-year-old woman with branch retinal artery occlusion is presented. The patient was affected by Ménière's disease and had a history of occasional migraine headaches. A thorough clinical and laboratory investigation showed a high cholesterol level. Retinal arterial obstruction is rare in young people and it is difficult to establish the precise cause. The presumed multifactorial etiologic factors are discussed.
