FIELD : medicine.SUBSTANCE : invention relates to medicine, specifically to ophthalmology. Following stages are carried out to activate the uveoscleral pathway of outflow of intraocular fluid in glaucoma of various aetiology : performing paracentesis, introduction into anterior chamber of carbachol solution 0.1?% 0.2?ml and solution of hyaluronic acid 1.4?% 0.2–0.3?ml, conjunctiva section at limb, separation of conjunctiva and tenon shell from sclera, cutting a surface scleral flap with a base to a limb, through incisions of deep scleral layers, performing cyclodialysis ab externo with a spatula, introducing non-absorbable collagen drainage into a cyclodialysis tunnel, sealing incisions of deep layers of sclera with interrupted sutures, closing surface scleral flap of sclera and conjunctiva with interrupted sutures. On the remaining deep layers of the sclera after cutting the superficial scleral flap, 2.0?mm from the posterior border of the surgical limb and parallel the limb, a horizontal through incision is made to the ciliary body. Further, along the horizontal incision edges, two through vertical incisions of the sclera are perpendicular to the limb in the sclera front part with size of 1.0?mm, thereby creating a valve, 0.1–0.2?ml of 1.4?% hyaluronic acid is introduced into the cycloidal tunnel previously formed by the spatula, and then the non-absorbable collagen drain tube.EFFECT : method enables activating the uveascleral pathway of the outflow of the IOF for a long period of time, achieving a stable hypotensive effect, reducing the number of hypotensive agents, reducing the number of intra- and postoperative complications, and reducing the length of the patient' s stay in the hospital.1 cl, 1 ex
