Abnormal vascular regulation in the ophthalmic artery of chronic heart failure patients

Abstract

In a previous article we described findings of color Doppler imaging of ophthalmic artery in chronic heart failure (CHF) patients(1). CHF patients presented lower blood flow velocities and higher resistance index in ophthalmic artery when compared to control group. Our research group also reported that CHF is associated with glaucomatous optic nerve head changes that correlate with ocular perfusion pressure (OPP) and echocardiographic parameters(2). Herein, we expand on these findings and show the relationship between OPP and blood flow parameters of ophthalmic artery in CHF patients.
