Abstract

The present invention is directed to a device and a method for the observation, documentation and/or diagnosis of the fundus in which the diagnosis is carried out by evaluating the documented images of the fundus. The device according to the invention comprises an ophthalmological examination device, a multi-spectral sequential illumination module, an image recording module, a control and safety module, and an evaluating unit. The illumination module which is connected to the ophthalmologic examination device has at least two individual light sources and which can be regulated individually with respect to intensity and duration and which emit monochromatic light of different wavelengths. The light coming from the illumination module is imaged on the image recording module from the ophthalmologic examination device by the eye being examined. The control and safety module controls the chronological sequence, duration and intensity of the individual light sources and monitors the light stress. An evaluating unit evaluates the recordings of the fundus transmitted by the image recording module. The inventive solution serves to record monochromatic images of the retina, for example, red,…
