[Contact glass for the study of the corneal endothelium and epithelium in the slit-lamp radius].
Specular endothelioscopy can be improved by an appropriate contact glass in three ways: The blurring front reflex of the cornea disappears, a two-fold magnification permits the use of routine slit-lamps for observation at higher magnification, and the field of specular illumination is increased considerably. The posterior surface of the contact glass is made plane, which offers the following advantages: a fluid chamber in front of the cornea is created which avoids any deformation of the cornea through the contact glass; the reflex of the posterior surface can be deflected by tilting the contact glass slightly so that the weak specular reflex of the epithelium becomes visible.
