A man in his early 80s with a history of systemic hypertension, coronary artery disease, and Janus kinase 2 (JAK2) mutation–positive thrombocytosis presented with 2-day history of sudden-onset visual field loss above fixation in the right eye. Best-corrected visual acuity was 20/30 OD and fundus examination revealed a 100 × 70-µm hollenhorst plaque in a distal, inferotemporal retinal arteriole with a wedge-shaped area of retinal whitening (Figure, A). En-face spectral-domain optical coherence tomographic angiography with Zeiss optical coherence tomographic angiography (Carl Zeiss Meditec Inc) demonstrated superficial and deep capillary nonperfusion (Figure, B). The patient had severe internal carotid stenosis on angiography and continued treatment with clopidogrel bisulfate.
