Effect of 10 Hz Flicker on Retinal Hemodynamics Measured by the Heidelberg Retina Flowmeter

Abstract

Localized flicker-induced increase in retinal and optic nerve head blood flow appears to be a replicable and robust phenomenon. Several investigators have shown that there are localized increases in retinal and optic nerve head (ONH) blood flow and velocity when the retina is stimulated by light flickering at around 10 per second.
