Method and apparatus for measuring blood oxygen levels in selected areas of the eye fundus

摘要: This invention provides for the measurement of relative oxygen saturation choriodal blood fundus eye a subject by directing into source beam light including incandescent, red and infrared light, combined penetrating choroid impinging on sclera eye, then being reflected back out as collimated light. The is directed to dichroic splitter where are separated from their respective intensities. measured intensities components compared with portion determine ratio oxyhemoglobin reduced hemoglobin.
