Does retinal vascular geometry vary with cardiac cycle
Investigative Ophthalmology & Visual Science, 08/09/2012
Hao H et al. – This study showed that there was minimal variations in the central retinal arteriolar equivalent (CRAE), CRVE, tortuosity, branching angle that are clinically used for two–dimensional measures of retinal vascular geometry during cardiac cycles. However, there was significant variation in the caliber of the individual vessels over the cardiac cycle.
