ABSTRACT:
An apparatus for detecting ophthalmic diseases in a patient's eye includes light projection system for projecting a laser beam at a 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. A monitor is provided in the light projection system for monitoring light scattered from the cornea of the eye on which the laser beam is projected, and for monitoring a virtual image which is formed by the cornea surface from light scattered at the exit window of the light projection system to correctly position and align the apparatus in order to ensure accurate protein concentration measurements.
