研究概览
简要总结
This study aims at evaluating changes occurring in the microvasculature of the retina primarily evaluated at the macular and peripapillary region through oct angiography in hypertensive patients in comparison to the normal control group. The study aims at picking up subtle signs of microvascular damage as measured by oct and octa technology well before clinical signs of hypertension manifest in the body.
