Abstract: Video-stereoscopic-image-producing system and a method for using the system is taught. The system is disclosed in conjunction with medical applications, specifically, in an embodiment useful for examining eyes. The system includes a binocular viewer for producing a pair of input images of an object which may be viewed to produce a stereoscopic image of the object. Video cameras are provided to receive a pair of images so produced and for producing, in turn, video signals representative of those images. An interface is provided for optically joining the video cameras to the binocular viewer. Video digitizing and freeze-frame equipment is joined to the cameras for generating a video display of the pair of input images and a stereoscopic viewer is provided for use with the video monitor for providing stereoscopic viewing of the displayed images by an observer.

Abstract: A laser canaliculostomy eye-treatment method and device for promoting drainage of aqueous humor from the anterior chamber. According to one manner of practicing the invention, blood exiting the Canal of Schlemm is blocked by rim pressure applied externally to the eye to engorge the Canal with blood--thus to shift the Canal's apparent color toward that of blood. With engorgement established, a laser beam is directed in a pulse to create a fluid drainage passage connecting the anterior chamber and the Canal. According to another way of practicing the invention, the two steps just mentioned are preceded by preliminary use of a similar laser beam to create a small "passage-starting" crater in the trabecular meshwork adjacent the Canal at the location where the final passage is intended to lie. A device for facilitating blood engorgement of the Canal of Schlemm includes a Goldman lens receiving portion and a flange which produces pressure on the eye, restricting the flow of blood in the Canal.
