METHOD OF SURGICAL TREATMENT OF REFRACTORY GLAUCOMA Russian patent published in 2009 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: invention relates to ophthalmology and can be used in refractory glaucoma treatment. Three recesses 15-18 mm deep are formed between Tenon's capsule and episclera in three quadrants between rectus muscles. Each cut of conjunctiva and Tenon's capsule is made 5-6 mm long with 6-8 mm indent from limb. In each recess near posterior eye pole in area of optic nerve collagen porous biological drainage is placed, made in form of plate 15 mm long, 8 mm wide from material containing bone collagen, isolated from spongy bone of farm animals. Then in fourth quadrant non-penetrating deep sclerlimbectomy with exposure of Shlemm's canal and limb edge of Descemet's membrane. Collagen porous biological drainage in form of plate 4.0 mm long, 1.0 mm wide and 0.5 mm thick made from material which contains bone collagen, isolated from spongy bone of farm animals and saturated with sulphated glycosaminoglycans is sewn with one end to Shlemm's canal. The other drainage end must protrude 1.0 mm from under superficial scleral flap, performing filtration pillow plasty. Superficial scleral flap is returned onto place and operation wound is sealed.

EFFECT: long-term IOP stabilisation, strengthening of eye posterior pole and improvement of optic nerve blood circulation, elimination of complications and possibility to perform YAG-laser goniopuncture in case of IOP rise.
