Investigation of methods of antiglaucoma surgery in order to control the cicatrization of filtration routes of intraocular fluid discharge is carried out at the Vladivostok Medical Institute since 1989. A total of 662 operations are analyzed, which were carried out using an original method with "inverted trapezium"-shaped dissection of the deep tissues of the sclera. A microsurgical knife designed by the authors and patented was used. The results of operations indicate their sufficiently high hypotensive effect and a low incidence of complications. The authors claim that several filtering components are advisable in antiglaucoma surgery. Simplification of the technique of antiglaucoma operation, based on the concept of micro-diastasis and micro-cavities, deserves to be further researched.
