Abstract

The present invention makes it possible to make high-quality recordings of the anterior and/or posterior segments of the eye as an individual image or also as a sequence of images without increasing the radiation load on the eye to be examined. In the method according to the invention, at least one pre-flash is used in order to determine an optimal exposure time for the main flash based on the recording of the pre-flash which is reflected by the object to be recorded. Both the pre-flash and the main flash are controllable and the recordings of the pre-flash and main flash are recorded with the same sensor of the electronic camera and are evaluated electronically by a control unit, and the recording of the main flash and, as the case may be, of the pre-flash is analyzed and/or corrected and displayed to the user.
