摘要

PROBLEM TO BE SOLVED: To find a lesion part at an eyeground at an early stage and accurately.SOLUTION: By irradiating an eyeground with a short-pulse laser beam for exciting a fluorescent dye for which the life of fluorescence is changed by being bonded to amyloid β protein as a target, setting the time point of emission of the laser beam as a reference, measuring light emission intensities at two different times t1 and t2 which are predetermined periods of time after the reference, and generating a fluorescence image of the fluorescent dye bonded to the target on the basis of the ratio of fluorescence intensities at the times t1 and t2, the fluorescence image projecting only the fluorescent dye bonded to the amyloid β protein contained in wastes in a yellow spot is generated. Thus, the presence/absence of drusen is found at an early stage and accurately.
