METHOD OF DETERMINATION OF THE STAGE OF PRIMARY OPEN-TINED GLAUCOM Russian patent published in 2017 - IPC A61F9/00 

FIELD: medicine.

SUBSTANCE: heidelberg retinal tomography (HRT) of optic nerve head (ONH) is performed before and after carrying out unload test. Coefficient of optic nerve head rigidity is calculated by formula: ONH RC=(dIOP/dCup Volume)/100, where ONH RC is coefficient of optic nerve head rigidity, dIOP is the difference of intraocular pressure before test and after test, dCup Volume is the difference in volume of excavation of ONH before and after test. At a value of less than the CD of OH 4.5 mm Hg/mm³ determine the first stage of POAG, 4.5-6.9 mm Hg/mm³ - The second stage of POAG, 7.0 mm Hg/mm³ and more - the third stage of POAG.

EFFECT: increase the accuracy of determining the stage of primary open angle glaucoma with the ability to identify the intermediate steps in the transition from the current stage of primary open angle glaucoma and adequate follow-up to the forecast of the disease.
