Adaptation of a digital camera for simultaneous stereophotography in ophthalmology

Simultaneous stereoscopic fundus photography is an important tool for classification and follow-up of glaucomatous optic neuropathy. The use of conventional film-based simultaneous stereoscopic fundus cameras is complicated and time-consuming due to film processing and the sensitivity of its mechanical components. Digital simultaneous stereoscopic fundus cameras are not available in Germany, since the existing ones are lacking the CE certificate. The authors realised a solution by transforming a conventional stereophotographic film-based fundus camera into a digital one. The analogue camera of the conventional stereophotographic device was replaced by a digital 36×24 mm full-frame complementary metal oxide (CMOS) camera.
