Abstract
A sterile drape for enclosing an ophthalmoscopic lens housing projecting from a surgical microscope has a wall defining a chamber of such size as to accommodate the lens housing and supporting parts. The chamber communicates with a compartment in which the lens housing may be accommodated and supported in an appropriate position. The compartment has transparent plates at its opposite ends and the chamber wall adjacent the opening has a circular lens which may underlie a microscope. The compartment plates and the circular lens enable the image to be transmitted from a surgical site without distortion while maintaining a sterile environment at such site.
