PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus capable of obtaining rapid and proper measurement and test results for an eye with a small pupil diameter, without going through complicated operations.SOLUTION: A size of a diaphragm aperture provided in a position optically conjugated with the pupil of a subjects eye or a light shielding unit provided in a position optically conjugated with the crystalline lens of the subjects eye or the cornea of the subjects eye can be switched between a first size in the case of the normal eye and a second size smaller than the first size. When the size is switched to the second size, the amount of light of a fixation target is kept in or changed to the smaller amount of light than in case of the normal eye.COPYRIGHT: (C)2013,JPO&INPIT【課題】小瞳孔径眼に対して、煩雑な操作を経ずに迅速で適切な測定・検査結果を得ることができる眼科装置を提供する。【解決手段】被検眼瞳孔と光学的に共役な位置に設けられる絞り開口、又は被検眼水晶体あるいは被検眼角膜と光学的に共役な位置に設けられる遮光部、の大きさに関し、通常眼の場合の第1の大きさと、第1の大きさより小さい第2の大きさを切り替え可能で、第2の大きさに切り替えられている場合には、固視標の光量を通常眼の場合より小さい光量に維持又は変更する。【選択図】図1
