The role of Perifoveal Arteriolar Tortuosity in Optical Coherence Tomography Angiography (OCTA) images as an early indicator of hypertensive retinopathy

Abstract

What is known

• The existing Scheie classification schema for hypertension is subjective in nature with challenges in consistent identification of early hypertensive changes in the retina.

What is new

• Perifoveal arteriolar tortuosity differs significantly between early hypertensive and control patients.

• Arteriolar tortuosity may be a potential biomarker that is useful in identifying patients who have early hypertensive changes in the retina.
