Abstract:
A new glaucoma filtration procedure was performed in nine rabbits in a preliminary trial. A silastic tube with an internal diameter of 0.35 mm was passed across the anterior chamber through two limbal openings, and the free ends were buried postequatorially in sub-Tenon's space. At a later date, using an Nd:YAG laser in the thermal mode, holes 0.05 to 0.30 mm in diameter were burned in the tube in the anterior chamber. This procedure significantly lowered intraocular pressure in four rabbits on two successive tries; however, a third treatment given in two cases did not further decrease the pressure.
