ABSTRACT:
Upon detecting a selection of an examination start button, a start and completion management unit starts an examination. The control unit switches an observation state to an infrared light observation by an observation switching unit. Next, an examiner performs alignment while observing an eye to be examined, and photographs the eye to be examined with a photographing unit. The start and completion management unit determines whether the examination is completed according to a selection of an examination complete button, and repeats the alignment until it is determined that the examination is completed.
