Autograft cornea drainage the trabeculectomy antiglaucomatous operations
Purpose: To study a possibility of use autograft cornea at trabeculectomy operations at patients with earlier operated glaucoma. Methods: 60 patients (60 eyes) participated in research with primary open-angle before operated not compensated glaucoma. Patients have been divided into 2 groups: I group experimental (30 patients, 30 eyes) at which carried out new operation trabeculectomy with autograft cornea and II group control (30 patients, 30 eyes) where outcome standard trabeculectomy. Results: After operative intervention through 22.0±1.3 month marked significant reduction decrease IOP in comparison with an initial level, that in experimental group has made 16.9±1.5 mm Hg, and in control group 20.1±1.9 mm Hg. In the percentage ratio in comparison with initial parameters IOP in experimental group has decreased on 42.3%, and in control group-29.5%. Results of an optical coherent tomography (OCT) have allowed confirming availability of a cavity between cor-neal and scleral flap that allows to prevent sclera-scleral scarring stable hypotensive effect of operation. Besides according to ОСТ tendencies of growing corneal epithelium in the forward chamber in the remote timeframes by us it is noted. Conclusions: Stable hypotensive effect at carrying out of new modification trabeculectomy operations is caused by creation of an additional way of outflow between corneal and scleral flap that prevents sclera-scleral scarring. Use in surgery autograft additional element of surgical intervention, does not require special technical equipment, of bioassay also, getting this stuff does not involve additional material costs.
