To date, the factors affecting the course of the reparative process after non-penetrating deep sclerectomy (NPDS) have not been fully determined. There is no systematic information about the regulatory role of the cytokines TGF-β, IL-6, IL-8 and MMP-9, VEGF A 121 and 165 in the formation mechanisms of the newly created pathways consistency of intraocular aqueous humor outflow.Purpose. To determine possible ways of impact of biologically active aqueous humor molecules of the anterior chamber and lacrimal fluid on the hypotensive effect of non-penetrating deep sclerectomy.Methods. A prospective study of 65 patients with open-angle glaucoma before and 12 months after NPDS and 22 patients without eye hydrodynamic disorders with the determination of the initial concentrations of biologically active molecules in the lacrimal fluid and aqueous humor of the anterior chamber. Twelve months after NPDS all patients were divided into three groups, depending on the hypotensive effect of the operation, according to the criteria.Results. Multivariate discriminant analysis showed the greatest inter-group differences, calculated by the square of the Mahalanobis distance, between group 3 with no hypotensive effect of NPDS and the control group (R2 = 8.48, p = 0.001). The most informative features that determine the differences between the 4 groups in the total population, calculated according to the Fischer F-test, were MMP-9 (F = 14.7, p = 0.001) and TGF-β (F = 7.08, p = 0.001) in the aqueous humor of the anterior chamber. In pairwise comparison of groups 1 and 2, the maximum level of significance according to the F-criterion was characteristic of the level of tear IL-6 (F = 21.25, p = 0.001), with approximately equal degree – IL-8 (F = 7.85, p = 0.001) and VEGF (F = 7.12, p = 0.001), to a lesser extent TGF of aqueous humor (F = 4.43, p = 0.001) and MMR-9 (F = 2.23, p = 0.001). Between groups 1–3, the maximum differences according to the Fisher criterion were observed in the IL-8 (F = 20.99, p = 0.001), TGF (F = 8.75, p = 0.001) and to a lesser extent – TGF (F = 5.83, p = 0.001).Conclusion. The analysis of the obtained data showed the decisive role of the imbalance of proinflammatory cytokines, signaling proteins with prolymphoangiogenic activity, and MMP-9 in the aqueous humor of the anterior chamber, as well as in the initial state of the lacrimal fluid in the postoperative healing processes after NPDS.
