    Optical coherence tomography angiography (OCTA) findings of microvascular and neural changes in primary pulmonary hypertension

    Aim: To investigate the microvascular and neural changes in primary pulmonary hypertension (PPH) patients compared with healthy controls. Method: Forty-four eyes of 22 PPH patients were included in this observational clinical cohort study, while forty-four eyes of 22 healthy participants were enrolled as controls. Optical coherence tomography angiography (OCTA) images were obtained from each participant using the RTVue XR Avanti device with AngioVue software 2.0.
