PROBLEM TO BE SOLVED: To provide an eyeball optical measurement apparatus, etc. that allow the position at which an eyeball is projected with light to be controlled based on the light path observed, compared with when an eyeball observation unit is not provided.SOLUTION: An eyeball optical measurement apparatus 1 includes: a light projection unit 20A for projecting light toward an anterior chamber 13 of an eyeball 10 of a subject a light receiving unit 20B for receiving light transmitted through the anterior chamber 13 an eyeball observation unit 40 for observing an optical path to the eyeball 10 while light is projected from the light projection unit 20A and a control unit 60 for controlling the light projection unit 20A to change a position at which the eyeball 10 is projected with light based on the result of the eyeball 10 being observed by the eyeball observation unit 40.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】眼球観察部を備えない場合に比べて、観察した光路に基づいて眼球への光の照射位置が制御できる眼球の光計測装置などを提供する。【解決手段】眼球の光計測装置1は、被計測者の眼球10の前眼房13に向けて光を照射する光照射部20Aと、前眼房13を透過した光を受光する受光部20Bと、光照射部20Aから光が照射されている状態で、眼球10に対する光路を観察する眼球観察部40と、眼球観察部40による眼球10の観察結果に基づいて、眼球10への光の照射位置を変更するように、光照射部20Aを制御する制御部60とを備える。【選択図】図1
