METHOD FOR PREDICTION OF INEFFECTIVENESS OF LASER DESCEMETOGONIOPUNCTURE CAUSED BY EARLY RECURRENT OPHTHALMOHYPERTENSION FOLLOWING NONPENETRATING ANTIGLAUCOMATOUS OPERATIONS Russian patent published in 2010 - IPC A61F9/00 A61F9/07 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, more specifically to ophthalmology and can be used for prediction of ineffectiveness of laser descemetogoniopuncture (DGP) to 3 months following nonpenetrating antiglaucomatous operations. It involves ultrasonic biomicroscopy (UBM) of an operative zone to estimate a status of an angle of anterior chamber (AAC), to evaluate acoustic density, thickness, width and profile of trabecule Descemet's membrane (TDM), to measure height of intrascleral cavity (ISC), thickness and acoustic density of a scleral flap (SF), to estimate a status of a hypoechoic tunnel from under the SF. If in the operative zone there are observed prominent TDM, disappeared ISC or ISC of height 0.15 mm and less, ineffectiveness of laser DGP is predicted. If TDM thickness exceeds 0.15 mm, TDM acoustic density exceeds 85%, ISC height is less than 0.25 mm, then ineffectiveness of laser DGP is predicted. If TDM width is less than 0.4 mm, TDM thickness is equal or more than 0.13 mm, and TDM acoustic density exceeds 75%, ineffectiveness of laser DGP is predicted. If SF thickness is more than 0.4 mm, SF acoustic density is equal or exceeds 90%, the hypoechoic tunnel from under the scleral flap is not differentiated, ineffectiveness of laser DGP is predicted. If TDM is covered with an iris root more than by 4/5 or more than its width, ineffectiveness of laser descemetogoniopuncture is predicted.

EFFECT: method allows for higher accuracy of early (approximately 3 months) prediction of ineffectiveness of laser descemetogoniopuncture (DGP) following nonpnetrating antiglaucomatous operations by the ultrasonic biomicroscopy (UBM) method that will enable laser intervention by indication, and thereby will improve treatment quality in the patients suffering from primary open-angle glaucoma.
