Retinal Microvascular Change in Hypertension as measured by Optical Coherence Tomography Angiography

Many studies have reported the effect of hypertension on microcirculation of the retina. Advance of optical coherence tomography angiography (OCTA) allows us more detailed observations of microcirculation of the retina. Therefore, we compared OCTA parameters between chronic hypertension (disease duration of at least 10yrs; Group A, 45 eyes), relieved hypertensive retinopathy (grade IV HTNR1yr prior; Group B, 40 eyes), and normal controls [Group C (50 eyes)50yrs old and Group ...
