The aim of the study: to evaluate the clinical efficiency of using the implant from pericardial membrane in the surgical treatment of patients with primary glaucoma.
Patients and Methods: We examined 30 patients after a standard operation - deep sclerectomy (control group) and 30 patients after a standard operation with the use of an implant from the pericardial membrane (the main group). The pericardial membrane is a very thin film of polytetrafluoroethylene that has high biocompatibility, antimicrobial properties, it retains its volume after implantation, it is not subject to degradation and has no reabsorption. The implant from the pericardial membrane in the form of a strip of 0.1 x 2.0 x 25 mm was placed in the scleral bed and moved under tenоnova capsule towards the posterior pole of the eye. The efficacy was assessed by IOP level, eye hydrodynamics, the field of view and visual acuity. Data were statistically processed using standard computer programs.
Results: the postoperative period in both groups proceeded in the same way. For the first 3 months after surgery there were no significant differences in the indicators of both groups, but after 3 months till 1 year period the level of IOP, С, СB was significantly better in the group of patients operated with the use of the implant from a pericardial membrane. This contributed to the preservation of visual function at baseline. During examination of patients in a year after surgery IOP without ocular hypotensive drops were kept at a level to 21 mm Hg.St. in 73.3% in the main group and in the control group in 40% of cases. 
Conclusion: implant of a pericardial membrane does not cause an inflammatory reaction of the surrounding tissues, prevents obliteration of the newly created aqueous outflow ways, delays the development of scar tissue, enhances the hypotensive effect and can be used in surgical treatment of patients with primary glaucoma.
