Since the development of the first slit lamp by A. Gullstrand in 1911 this instrument is an indispensible part of our diagnostic repertoire. Nevertheless it was not until almost 40 years later that the slit lamp could be able to be used for the examination of the fundus as a result of the development of the Goldmann 3-mirror contact glass. Because of the increasing importance of antiretinal detachment prophylaxis the slit lamp examination also of the rear end of the eye its becoming more and more important because of its good stereoscopy, the excellent illumination and the high magnification. A newly developed slit-lamp apparatus fulfils these special requisites which have firstly been demanded recently. This apparatus is easy and comfortable to use, which makes easier above all the contact glass examination. Technical factors, possibilities of application and experience with this slit-lamp are discussed.
