    摘要: 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.

    摘要: 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.

    摘要: The present invention is directed to an optical device for the observation and documentation of the ocular fundus and is preferably provided for fundus cameras. In order to generate a uniform illumination of the fundus by transillumination of the sclera in the illumination unit, according to the invention, for fundus cameras and/or ophthalmoscopes, the light emitted by the illumination source is coupled into individual light-conducting fibers or bundles of light-conducting fibers which extend into the area of the front lens of the fundus camera and ophthalmoscope and whose fiber ends are formed in such a way that the exiting light is projected on and transilluminates the sclera. The discomfort caused to the patient by pupil-dilating means is avoided as are the risks associated with the placement of contact lenses. Another substantial advantage of the illumination unit according to the invention is the extremely uniform, large-area illumination of the fundus, so that a correspondingly large visual field of the fundus can be observed and also documented.
