Idiopathic Recurrent Branch Retinal Arterial Occlusion

Recurrent multiple branch retinal arterial occlusions of unknown cause occurred in nine apparently healthy individuals. With the exception of three patients who developed associated auditory symptoms, none developed other signs or symptoms of systemic vascular disease. Ophthalmoscopic and fluorescein angiographic findings suggested focal arteritis and arteriolitis as the cause of the obstructions. Most patients retained good visual acuity.
