title: [Prototype of an ophthalmoscope for studying an upright image with light amplification].
abstract: The instrument described here is the prototype of a direct ophthalmoscope with amplification of available light. The beam path has already been published and patented under reference number 3124305. It does not require drug-induced mydriasis, reduces light toxicity of the retina, and facilitates examination of pre-eclamptic and other patients who are sensitive to light. With this ophthalmoscope it may be possible to demonstrate the autofluorescence of the hyalocytes, described by Cremer-Bartels and Balacz.
