[Conduit drainage and preserved amnion in pathologies of the cornea concomitant with glaucoma]

The authors improved the anterior-chamber bypass technique implemented simultaneously with reconstructive penetrating keratoplasty or with trabeculotomy in order to enhance the efficiency of antiglaucomatous drainage surgeries in organic lesions of the anterior segment of the eye combined with active inflammatory processes in it and concomitant with secondary glaucoma. The use of conduit drainage was supplemented with wrapping the distal end with conserved amnion, which prevented the postoperative obstruction of drainage or its heading in the outward direction. Amnion, exceeding the size of the scleral flap, was placed in trabeculotomy with active inflammatory signs between scleral strata, thus, preventing an excessive postoperative scarring. A total of 45 patients were operated on with the follow-up reaching 3 years. The efficiency of antiglaucomatous interventions made up 88-93% of cases. The suggested new drainage techniques with conserved amnion can be successfully used surgeries combined with keratoplasty as well as in independently in secondary glaucomas of various etiologies and in primary refractive glaucoma.
