[The efficacy of optimized sinusotrabeculectomy in primary open-angle glaucoma based on the late results data].

In 210 patients (210 eyes) with open-angle glaucoma, remote results (3 years) after sinusotrabeculectomy in Cairns-Krasnov's modification were compared with those after optimised performance of main surgical stages. Separation of a scleral flap at the depth of 350-400 mcm, localization of the drainage system by a developed microdiaphanoscopic method and subsequent removal of a fragment of the Schlemm canal and trabeculae provide a more stable hypotensive effect and preserve visual functions as compared with results of traditional methods. High effectiveness of the method is connected with avoiding of such variants of the surgical technique that can lead to development of complications.
