A digital scanning laser ophthalmoscopy image of the rat fundus during fluorescein angiography. The retinal vessels: retinal artery (open star), retinal vein (solid star), and retinal capillary (arrowhead) can be distinguished. The choroidal vessels (white arrows) can also be observed as faint structures behind the retinal vasculature.

A "pair" of carboxyfluorescein labelled leucocytes flowing through a retinal capillary (main window, arrowheads). The "pair" of cells (see smaller window), actually represent only one flowing leucocyte and appear double owing to the combined result of the interlaced scanning system of the SLO and the rapid movement of the leucocyte. The leucocyte is travelling so fast that it is captured "twice" by the scanning system of the SLO, thus giving the misleading appearance of two cells. This feature can be used to calculate the velocity of the leucocyte.
