[Effectiveness of sub-Tenon's capsule implantation of collage sponge in the treatment of glaucomatous atrophy of the optic nerve].

The surgery of "subtenon implantation of collagen sponge" is offered; its essence is in implanting a fragment of hemostatic collagen sponge for the purpose of revasculizing and improving the trophism of the retina and optic nerve. A total of 96 patients (105 eyes) with glaucomatous atrophy of the optic nerve were operated on. The reliable results of visometry as well as of kinetic and static perimetry and of rheography were obtained. The efficiency of the surgery (without any additional conservative therapy) ranged from 63.4 to 78.6% according to various examination methods. The visual functions improved within 6 to 12 months after surgery.
