摘要
A microscope, whose ocular tubes receive light that is reflected by the blind spot or another selected portion in the innermost part of a human eye in response to illumination by a flash unit or a slit lamp, contains an ocular-like casing which replaces one of the oculars and contains a photodiode located in the respective image plane and generating signals denoting the intensity of light in the respective image plane. Such signals are transmitted to one input of a dividing circuit which further receives signals denoting the intensity of light which is emitted by the light source of the flash unit or slit lamp. The signal at the output of the dividing circuit is displaced and/or recorded and is indicative of reflectivity of the selected portion. The other ocular tube of the microscope contains a customary ocular with a marker located in the respective image plane.
