The paper analyses immediate and remote (from 3 to 10 years) results of sinusotrabeculectomy in initial open-angle glaucoma in 184 patients (300 eyes). Normalization of intraocular pressure was achieved in 77.7% of cases (20.12 +/- 2.1 mm Hg, at the average). Tonographic and rheographic values in the operated patients achieved the normal levels (P0 = 15.3 +/- 0.68 mm Hg, C = 0.28 +/- 0.03 mm3/min., P0/c = 68.08 +/- 3.12, RC = 2.7 +/- 06.09). The dynamics of visual functions showed stabilization of the process in 85.1% of cases. However, in 15% of cases the glaucomatous process progressed, mainly in persons who failed to receive medicamentous treatment regularly in the postoperative period.
