Comparative Analysis of the Retinal Microvasculature Visualized With Fluorescein Angiography and the Retinal Function Imager

RFI, a noninvasive retinal imaging instrument, revealed vessel loops, vertical collateral vessels, the area of the FAZ, and order of vessel branching in greater detail than IVFA. This instrument may be helpful in understanding dynamic retinal vascular changes in a number of common ocular diseases, as well as in normal eyes.
