ABSTRACT:
An apparatus for detecting ophthalmic diseases such as an inflammation in a patient's eye which includes means for focusing a laser beam at a selected spot in the eye. The light scattered from the eye is photoelectrically detected and converted into an electrical signal which is subsequently used to determine the protein concentration essential to ophthalmic disease detection in the patient's eye. The laser beam is deflected vertically and horizontally. The electrical signal derived from the vertical scanning is compared with the other electrical signals from the horizontally shifted scanning of the laser beam to remove noises from the electrical signal.
