Abstract
An apparatus operates in an observation mode for determining a specific spot within the eye of a patient and operates in a measurement mode for measuring protein particles contained within the specific spot. The eye is illuminated with a slit light to determine a specific spot. A laser light is irradiated onto the determined specific spot. A scattered light scattered by protein particles is detected by a detector to measure the protein particles. Shutter members are actuated in the observation mode to unblock the slit light to thereby effect the determination of the specific spot, to block the laser light to thereby protect the eye, and to block the scattered light to thereby protect the detector, and actuated in the measurement mode to block the slit light to thereby prevent the slit light from being scattered by the protein particles, to unblock the laser light to thereby allow the laser light to be scattered by the protein particles and to unblock the thus scattered light to thereby effect the measurement of the protein particles.
