title: Vitreous hemorrhage and the Valsalva maneuver in proliferative diabetic retinopathy.
abstract: A 59-year-old man with bilateral proliferative diabetic retinopathy underwent fluorescein angiography as a baseline study. Soon after intravenous injection of fluorescein, the patient had an extended episode of vomiting resulting in bilateral vitreous hemorrhages. Photographic evidence is presented that confirms the clinical impression that vitreous hemorrhage may be precipitated by a Valsalva maneuver.
