Application of optical coherence tomography angiography macular analysis for systemic hypertension. A systematic review and meta-analysis.

Microvascular rarefaction of the macula is found in hypertensive patients with a reduction of foveal and parafoveal vessel density and an increase of foveal avascular zone area. Disease duration and severity might be related to a microvascular rarefaction. OCTA could offer a novel tool for the assessment and follow-up of hypertensive patients.
