Moyamoya (MM) disease is a chronic cerebrovascular disease that can lead to progressive stenosis of the terminal portions of the internal carotid arteries and their proximal branches. The authors carried out a cross-sectional cohort study to investigate vascular changes in patients with MM vasculopathy (MMV) using optical coherence tomography angiography (OCTA) compared to healthy controls. The results show retinal microvascular changes in patients with MMV in the absence of clinical signs or symptoms and highlights the potential of OCTA imaging for the detection of subclinical retinal pathology. Larger prospective studies and studies including optic nerve head data are required to further validate these findings.
