ABSTRACT:
An ophthalmic measurement apparatus in which the interior of a patient's eye is irradiated with a laser beam and the light scattered from the eye is detected and processed to determine the protein concentration in the eye. The apparatus employs a single-objective binocular observation section and a total-reflection mirror which allow these measurements to be carried out without decreasing the amount of light impinging on the photodetector used to detect the scattered light or the amount of light used by an observation section, and the apparatus can also be used as a slit-lamp microscope.
