[A comparative assessment of the effectiveness of sinusotrabeculotomy in different stages of open-angle glaucoma].

The paper analyses immediate and remote (to 4.5 years) results after sinusotrabeculotomy in 233 patients (244 eyes) with open-angle glaucoma. Among 244 eyes, 93 had initial, 87--advanced, and 64--far-advanced stages of glaucoma. It is recorded that such postoperative complications, as detachment of the choroid and hypotony, appear rarer in initial (12.5% and 15.0%, respectively), than in far-advanced (18.7% and 20.3%, respectively) stage of glaucoma. In remote terms after operation, the incidence of visual acuity and visual field preservation is higher in initial (92.5% and 95.7%, respectively), than in advanced (78.2% and 87.4%), and, in particular, far-advanced (70.3% and 79.7%) stages of the disease. After surgery at initial stage of glaucoma, restoration of tonographic values is more expressed (C = 0.24 +/- 0.004, F = 2.1 +/- 0.03), than at advanced (C = 0.23 +/- 0.007, F = 1.8 +/- 0.06) and far-advanced (C = 0.19 +/- 0.005, F = 1.1 +/- 0.04) stages. It is emphasized that in order to achieve the highest effectiveness of surgical treatment at the initial stage of open-angle glaucoma, the ophthalmic surgeon should be highly skilled in this field of surgical treatment of such patients.
