METHOD FOR LASER TREATMENT OF PRIMARY OPEN-ANGLE GLAUCOMA WITH NARROW ANGLE OF IRIS Russian patent published in 2013 - IPC A61F9/08 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly ophthalmology, and concerns the laser treatment of primary open-angle glaucoma with a narrow anterior chamber angle. A single pulse laser (Nd-YAG laser) of power 1.5-2.5 mJ, pulse quantity 1-4 is used for iridectomy. That is followed by YAG laser trabecular activation. A trabecular zone is exposed within the anterior chamber angle at the level of Schlemm's canal to Nd-YAG laser light at wave length 1064 nm, power 1.6-2.0 mJ. A spot diameter is 10-15 mcm, a pulse quantity equispaced along the whole circular length is 55-70.

EFFECT: method enables increasing the anterior chamber angle in the patients suffering narrow-angle primary glaucoma and evacuating the extracellular fine deposits from the intertrabecular sheets by mechanical movement both of pigment, and other deposits in a trabecular zone to normalise intraocular pressure.
