A Moyamoya Patient with Bilateral Consecutive Branch Retinal Vein Occlusion

We describe a moyamoya (MMD) patient with bilateral consecutive branch retinal vein occlusion (BRVO). The patient had a medical history of severe headache, cranial haemorrhage, bilateral supraclinoid carotid artery occlusion, and “puff of smoke” collaterals on cerebral angiography and an encephalomyosynangiosis operation. On ophthalmic examination, he had superior temporal branch vein occlusion with intraretinal haemorrhage and visual acuity of 20/25 in the right eye. Twelve years later, he presented with superior temporal branch vein occlusion in the left eye and visual acuity of 20/60. The patient was initially treated with a dexamethasone intravitreal implant, and later intravitreal ranibizumab injections. We describe the first reported case of bilateral consecutive BRVO and management in MMD.
