Abstract. Purpose:To report a case of multiple and recurrent branch retinal arterial occlusion. Case:A 17-year-old girl presented with blurring and visual field defect in her right eye. Her right eye showed white plaques along inferior temporal,superior temporal and superior nasal retinal arteries. She was diagnosed with branch retinal artery occlusion(BRAO). She showed no systemic disorders except for migraine since 7 years before. A similar episode occurred 3 months later involving both eyes. By cerebral angiography,her right ophthalmic artery received blood supply via external cerebral artery. Another attack of BRAO occurred in the left eye 10 months later,followed by similar ones in the right eye after 21 and 11 months respectively. She has been doing well now 16 years after her initial visit,with visual acuity of 1.5 in either eye. An arterioarterial collateral has formed in her right fundus. Conclusion:Recurrent and bilateral episodes of BRAO in the present case cannot be attributed to known causes including embolism,inflammation,or spasm of retinal arteries. There is a possibility of involvement by multiple unknown factors.
