Enhancing filtration in the early postoperative trabeculectomy refractory to digital massage.

Digital massage often can be used to lower intraocular pressure (IOP) after trabeculectomy or trabeculectomy combined with extracapsular cataract extraction and intraocular lens implantation. However, occasionally filtration, and thus IOP reduction, is refractory to massage. We present a pressure-lowering technique in which focal pressure is applied adjacent to the trabeculectomy flap firmly enough to indent the sclera and induce bleb formation.
