Pulmonary arterial hypertension (PAH) is a progressive disorder with systemic vasculopathy, and noninvasive assessment remains challenging. The retina, sharing anatomical similarities with the cerebral microcirculation, is an accessible site for visualizing systemic vascular compromise. This study quantitatively evaluated retinal microvascular and neuroretinal structural changes in PAH patients compared to healthy controls using optical coherence tomography angiography (OCTA).
