摘要：
FIELD: medicine.SUBSTANCE: invention relates to medicine, namely to ophthalmology, and can be used for prediction of ineffectiveness of laser reconstruction of antiglaucoma operation (AGO) zone of non-penetrating type in its block by iris root in different time after operation. Ultrasonic biomicroscopy (UBM) of operation zone is made with determination of acoustic density (AD) of outflow tract structures. AD is expressed in percentage of sclera AD in intact area, adopted as 100 %. Thickness of trabeculae-descemets membrane (TDM) and its width free from iris root are determined, in mm. Length of contact TDM with iris root is measured. Height of intrascleral cavity (ISC) is measured, in mm. Presence of inclusions in ISC is estimated. Presence of hypoechoic tunnel connecting ISC with filtration pad (FP) is estimated. Height of FP is determined in mm, echodensity of inclusions in it is also determined. If TDM thickness is more than 0.15 mm, TDM width, free from iris root, is less than 0.5 mm, TDM is in contact with iris root on 4/5 or more than its width, ISC height is less than 0.15 mm, it is filled with acoustic inclusions, there is no hypoechoic tunnel, there is no FP, ineffectiveness of laser reconstruction of AGO zone is diagnosed. If TDM thickness is more than 0.15 mm, there is contact of TDM with iris root of any length, ISC disappearance is detected, SF thickness is more than 0.4 mm or there is no possibility of differentiating SF borders, SF acoustic density exceeds 80 %, height of FP is less than 0.3 mm, AD of inclusions in FP exceeds 80%, ineffectiveness of laser reconstruction of AGO zone is diagnosed.EFFECT: method enables non-penetrating predicting ineffectiveness of laser reconstruction of AGO zone.2 cl, 2 exИзобретение относится к медицине, конкретно к офтальмологии, и может быть использовано для прогнозирования неэффективности лазерной реконструкции зоны антиглаукоматозной операции (АГО) непроникающего типа при ее блокаде корнем радужки в различные срок
