[High-speed recording of fluorescein fundus angiography using an argon laser as the illumination source].
We constructed a new fluorescein fundus angiography system using a speedy and sensitive fundus camera and an argon laser apparatus as the illumination source. The system consists of a fluorescein fundus camera, a high-speed camera, a digital recorder, an argon laser apparatus, and a cathode ray tube(CRT)monitor. The frame speed was 200 frames/s. It was possible to record high speed fluorescein angiography with lower illumination by using an argon laser as the illumination source. This system allowed us to measure the rate of blood flow in the retinal vessels because it easily detected the dye front in the retinal vessels.
