- Abstract: We describe two cases of branch retinal artery occlusion (BRAO) after carotid artery (CA) stenting. Case 1: A 57-year-old man diagnosed with left neovascular glaucoma was admitted to our department for trabeculectomy (He had complained of decreased visual acuity (VA) in the left eye for a month). A preoperative neck angio CT scan showed bilateral CA stenosis. After CA stenting, he contracted visual defects on the right superior area of his right eye. Upon examination, VA with correction was found to be 1.0 (OD), but right fundoscopy revealed ischemic retina whitening along the inferior temporal arcade. Case 2: A 64-year-old man received left CA stenting for severe stenosis in the Department of Neurology. The next day, he was referred to us for acute onset of a left naso-inferior visual field defect. Upon initial examination, his VA with correction was 0.8/0.16 (OD/OS) and fundoscopy revealed ischemic retina whitening at the superior posterior pole in the left eye. It was not necessary to treat the BRAO in these cases because the foveal capillary network was not invaded at 2 month follow ups, VA was preserved in both cases. In conclusion, ophthalmic evaluation is important after CA stenting because of a possible embolic occlusion of the retinal artery.
