REFLECTION MICROSCOPE FOR EXAMINATION OF THE CORNEAL ENDOTHELIUM AND METHOD OF OPERATING SAME

摘要

A method for operating an endothelium reflection microscope apparatus, the apparatus comprising an optical head (1) comprising: an illuminating system (16, 17, 18, 36), an eye-front observation optical system (12, 29, 2) along a central channel (15) in which an alignment-use light spot is received and imaged by a camera (2) comprising a digital optical sensor, and an enlarged­imaging optical system (24, 25, 26, 27) for enlarged observation or photographing of the subject part by said digital camera (2), the apparatus further comprising drive means (6) for moving the optical head (1) and CPU control means (3) for automatically controlling said drive means (6), said illuminating system and said eye­front optical system, the method being characterized by an endothelium image acquisition procedure in which the grey level inside a check area (34) of said camera sensor is constantly checked during the advancement along an advancement direction (Z-); when said grey level reaches a predetermined threshold value, a delay time (it) is triggered; and when said delay time (at) lapses, the acquisition of one or more images of the endothelium by the digital camera (2) is enabled.
