Abstract

A fundus camera for the recording of high-resolution color images of the fundus of non-dark-adapted eyes, and without the use of a mydriatic. The fundus camera has a strip-shaped pupil division, and includes a coherent or incoherent illumination source with illumination optics, a deflection mirror and an ophthalmoscope lens for illuminating the eye, detection optics and a detector for detecting the light reflected by the eye, and a control and evaluation unit. The deflection mirror has a strip shape, and the spatially resolving detector can be activated and read out in sectors. The control and evaluation unit connects the data read out in sectors in the form of a bright image from the detector and produce a resulting fundus image. The fundus camera records images of the fundus when the eyes are not dark-adapted for this purpose and no mydriatic has been used.
