[Laser-trabecular puncture. Experimental studies].

From the presented evidence it may be seen that a sufficiently strong laser beam can produce performation openings in trabecular meshwork. We were using an exposure time of maximum 200 msec in order not to produce thermal reactions in surrounding tissues. The 1.6 W used by us was sufficient with the above exposure time to produce repeatedly openings in trabecular meshwork. Following this procedure perfusion of Schlemm's canal experiments let the used dye pass through artificially made openings, only slightly staining the trabecular meshwork.
