Abstract
An optical measurement apparatus includes: an emission section that emits light such that the light travels across an anterior chamber of an eyeball of a measurement subject; a light reception section that receives light that is emitted from the emission section and travels across the anterior chamber; and a positioning section that performs positioning of one of the emission section and the light reception section at a position where skin on a periphery of an inner canthus of the eyeball is squeezed into an eye socket accommodating the eyeball.
