METHOD AND APPARATUS FOR MEASURING BLOOD STREAM OF EYEBALL

摘要

Apparatus for measuring the flow of blood in the eye, in which a fluorescent substance is introduced into the bloodstream, which substance is responsive to exposure to light of a wavelength in a first range by emitting fluorescent light of a wavelength in a second range essentially separated from the first range. The eye (13) is illuminated by a light source (3) emitting light of a wavelength in the first range. Fluorescent light is applied to a detector (22) responsive at least to light of a wavelength in the second range, which detector is adapted to produce an electrical signal proportional to the amount of fluorescent light received at each moment. The electrical signal is applied to a processing device (24).
