PROBLEM TO BE SOLVED: To provide an optical measurement device for eyeballs and the like capable of facilitating arrangement of light-emitting means or light-reception means in an inner canthus side compared with a case where light is emitted or received with an eyeball facing the front, in a case of emitting light to traverse the anterior chamber of the eyeball and receiving light exited from the eyeball to traverse the anterior chamber.SOLUTION: An optical measurement apparatus 1 includes an optical system 20, which is used to measure the characteristics of the aqueous humor in the anterior chamber 13 of the eyeball 10 of a measurement subject, and a holding unit 50, which holds the optical system 20 and the like, and the optical system 20 is provided with a light-emitting system 20A and a light reception system 20B. A light path 28 is set in a manner such that when the eye 10 abducts, the light exiting the light-emitting system 20A passes through the anterior chamber 13 in a manner so as to traverse same, and can be received by the light reception system 20B. 【課題】眼球の前眼房を横切る光を出射し、前眼房を横切って眼球から出た光を受光する場合において、眼球が正面を向いた状態で光の出射及び受光をする場合に比べ、目頭側における光出射手段又は受光手段の配置が容易な眼球の光計測装置等を提供する。【解決手段】光計測装置１は、被計測者の眼球１０の前眼房１３における眼房水の特性の計測に用いる光学系２０、光学系２０などを保持する保持部５０を備え、光学系２０は、発光系２０Ａと受光系２０Ｂとを備えている。光路２８は、眼球１０が外転したとき、発光系２０Ａから出射した光が前眼房１３を横切るように通過し、受光系２０Ｂで受光できるように設定されている。【選択図】図１
