The figure (right) shows the screen of the LSFG system's analysis software. In this example, a blood flow map of the area called the optic nerve head of the human eye is being measured and displayed. The red areas represent the retinal blood vessel portions extending from the optic disc to the surrounding area. This blood flow map has a size of 750 x 360 pixels, runs at 30 frames per second, and can be observed continuously in real time — this is the greatest feature of this system that other devices cannot replicate. Click here to see the real-time changes of the blood flow map. The measurement area has been expanding year after year with improvements in the device, and currently the entire optic nerve head region can be observed in a single measurement. Software is also being improved to automatically stitch images together to observe an even wider area. The figure (below) shows the analysis of blood flow fluctuations within a single blood vessel; such measurements can also be easily performed.
