Title:
FLUORESCENCE MEASUREMENT DEVICE AND FLUORESCENCE MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2014/181744
Kind Code:
A1
Abstract:
Provided are a fluorescence measurement device and a fluorescence measurement method with which safety can be improved and stable measurement values can be obtained. Excitation light from a light source (21) is directed at the sclera (11) of a subject's eye (1). Fluorescence from the sclera (11) irradiated with the excitation light is received with a photodetector (34). A calculation unit (4) carries out a calculation on the basis of received light intensity at the photodetector (34). Since the excitation light can be prevented from entering inside the eye (1) by directing the excitation light at the sclera (11) of the eye (1), safety can be improved. Additionally, by directing the excitation light at the sclera (11) of the eye (1) where there are less impediments that prohibit the excitation light and fluorescence from passing through and carrying out the calculation by receiving the fluorescence from the sclera (11), a stable measurement value can be obtained.
