Abstract (in Japanese) (See Japanese page) 
(in English) A possibility of detecting Alzheimer's Disease (AD) is examined using
pupil light reflex (PLR) with melanopsin-containing retinal ganglion
cells (ipRGCs).
PLRs for chromatic stimuli were recorded for 14 AD patients and 21
healthy participants, and some features of the waveform shapes in their
PLRs were extracted by Fourier descriptor technique. The possibility of
detecting AD patients was evaluated using discrimination analysis with
random-forest method. Classification performances of healthy and AD
patients were compared between conditions of chromatic stimuli. Also,
effectiveness of combining features across phases of PLR was
discussed.
