Abstract
Polymorphism of genes of transforming growth factor TGFB and its receptors (TGFBRI, TGFBRII, and TGFBRIIII) in patients with primary open-angle glaucoma was analyzed. The frequency of the TGFBRII CC genotype in patients is increased relative to the control group (OR=6.10, p=0.0028). Heterozygosity in this polymorphic position is reduced (OR=0.18, p=0.0052). As the effects of TGF-β is mediated through its receptors, we analyzed complex of polymorphic variants of the studied loci in the genome of patients. Two protective complexes consisting only of receptor genes were identified: TGFBRI TT:TGFBRII CG (OR=0.10, p=0.02) and TGFBRII CG:TGFBRIII CG (OR=0.09, p=0.01). The study showed an association of TGFBRII polymorphism with primary open-angle glaucoma and the need to study functionally related genes in the development of the disease, which should contribute to its early diagnosis and prevention.

Abstract
The proliferative activity of populations of stromal cells (fibroblasts) obtained from human corneal lenticles under conditions of their differentiation into keratocytes was studied. It was shown that during differentiation, the number of dividing fibroblasts and the frequency of divisions, and motor activity of these cells (speed of movement along the cell trajectory and the length of the trajectory) sharply decreased. These findings indicate a decrease in the proliferative activity of fibroblasts under conditions of their differentiation and transformation into keratocytes. A period of 17 days is sufficient for differentiation of corneal fibroblasts into keratocytes.

Abstract
Fibroblasts isolated and expanded from ReLEx SMILE lenticules can be a source of human keratocytes. Since corneal keratocytes are quiescent cells, it is difficult to expand them in vitro in suitable numbers for clinical and experimental use. In the present study, this problem was solved by isolating and growing corneal fibroblasts (CFs) with a high proliferative potential and their reversion to keratocytes in a selective serum-free medium. Fibroblasts reversed into keratocytes (rCFs) had a dendritic morphology and ultrastructural signs of activation of protein synthesis and metabolism. The cultivation of CFs in a medium with 10% FCS and their reversion into keratocytes was not accompanied by the induction of myofibroblasts. After reversion, the cells spontaneously formed spheroids and expressed keratocan and lumican markers, but not mesenchymal ones. The rCFs had low proliferative and migratory activity, and their conditioned medium contained a low level of VEGF. CF reversion was not accompanied by a change with the levels of IGF-1, TNF-alpha, SDF-1a, and sICAM-1. In the present study, it has been demonstrated that fibroblasts from ReLEx SMILE lenticules reverse into keratocytes in serum-free KGM, maintaining the morphology and functional properties of primary keratocytes. These keratocytes have a potential for tissue engineering and cell therapy of various corneal pathologies.

Abstract
Existence of lymphatic outflow of intraocular fluid is still an open question. Identification of the lymphatic capillaries and vessels in various human organs in normal and pathological conditions became possible with discovery of endotheliocyte markers for lymphatic vessels. However, the available information on the presence of lymphatic structures in the human eye is inconsistent and uncertain. The data on lymphatic drainage of the eye is of interest, particularly because it may help understand glaucoma pathogenesis, mechanisms of development of eye inflammatory diseases, and develop pathogenetic therapies. The article reviews literature and presents the authors' own views on lymphatic drainage of the human eye.

Abstract
Epidemiological investigation of pseudoexfoliative syndrome (PEX) as a glaucoma predictor is necessary for antiglaucoma treatment planning. AIM To study the prevalence of PEX and pseudoexfoliative glaucoma (PXFG) among healthy people, naïve patients, and patients under observation as well as to evaluate the hypotensive efficacy of bimatoprost/timolol fixed combination (FCBT) over 4 months in PXFG. MATERIAL AND METHODS Epidemiological analysis, ophthalmological examination, statistical analysis. RESULTS The prevalence of PEX among healthy Novosibirsk and Novosibirsk region citizens is 19.9%. In ophthalmologically compromised population and first-time patients, the prevalence of PEX is 24%, of which PXFG constitutes 57.2%. Retrospectively, the prevalence of PXFG in PEX patients who were treated and followed up appeared to be as high as 60.8%. PXFG also accounts for 70% of all open-angle glaucoma cases in the Novosibirsk region, which is much higher than the corresponding rates in the European part of Russia. A 4-month FCBT therapy in 5 groups of PXFG patients (no treatment, monotherapy, another fixed combination, two drugs, three drugs) has yielded an evident hypotensive effect in most patients. The decrease in intraocular pressure was clinically significant in all groups. CONCLUSION There has been found a high prevalence of PEX and PXFG in the Novosibirsk region. FCBT has demonstrated high hypotensive efficacy at all stages of PXFG and was beneficial even in patients treated with other medications or fixed combinations and in refractory cases.

Abstract
PURPOSE The purpose was to measure the concentrations of various cytokines and growth factors (including vascular endothelial growth factor [VEGF] and pigment epithelium-derived factor [PEDF]) in the vitreous of patients with proliferative diabetic retinopathy (PDR) and to investigate interaction between inflammatory and proliferative factors in the genesis of PDR. Materials and Methods : Vitreous samples from 32 eyes with PDR and 25 eyes without diabetes mellitus and signs of DR (control) were collected. Vitreous concentrations of VEGF, PEDF, monocyte chemotactic protein-1 (MCP-1), interleukin-4 (IL-4), IL-6, IL-8, IL-10, IL-17A, and secretory immunoglobulin A (sIgA) were simultaneously measured using enzyme-linked immunoassay. Results : Vitreous levels of VEGF, PEDF, IL-17A, IL-6, IL-8, IL-4, and sIgA were significantly (Π < 0.05) higher in eyes with PDR compared to control. The concentration of VEGF was more than 17-times higher than in control, and the concentration of PEDF was not changed oppositely and was also higher (1.45-times) compared to control, that may indicate disturbances of compensatory mechanisms in angiogenesis regulation in PDR. Significant (Π < 0.05) positive correlations were observed between vitreous concentrations of VEGF and IL-17ΐ (r = 0.45), VEGF and IL-8 (r = 0.48), VEGF and IL-4 (r = 0.51), PEDF and IL-17ΐ (r = 0.48), PEDF and IL-8 (r = 0.59), MCP-1 and PEDF (r = 0.72), MCP-1 and IL-8 (r0 = 0.45), IL-4 and IL-17ΐ (r = 0.65), IL-4 and IL-8 (r = 0.71), IL-8 and IL-17ΐ (r = 0.59). CONCLUSIONS Significantly raised levels of inflammatory and proliferative factors and numerous positive correlations between them may demonstrate a significant role of activation of vascular proliferation and local inflammation in the pathogenesis of PDR.

Abstract
AIM To establish possible association between age-related macular degeneration (AMD) and cytokine genotype polymorphisms; for that promoter regions of a number of cytokine genes were studied, namely, TNF-A863C, TNF-A308G, TNF-A238G, IL1β-C-31T, IL4-C590T, IL6-C174G, and IL10A-1082G. MATERIAL AND METHODS A total of 102 AMD and 100 non-AMD participants in the same age range were examined at the Novosibirsk branch of the Academician S.N. Fyodorov IRTC «Eye Microsurgery». In all cases restriction fragment length polymorphism analysis was performed. RESULTS The frequency of TNF-308 GA and IL10-1082 GG genotypes was higher in AMD patients than in the controls, while the TNF-308 АA minor genotype has proved protective against the disease. Moreover, AMD has been found to be positively related to 48 genotypic combinations and negatively - to 32 (with specificity as high as 98-99%). The odds ratio was also higher in combination analysis as compared to monogenotypes. CONCLUSION Complex genetic analysis of cytokines gives an idea of the balance of proinflammatory and anti-inflammatory cytokines in AMD and, therefore, plays an important role in studying the disease pathogenesis and exploring therapeutic options.

Abstract
Using light microscopy, immunohistochemistry and electron microscopy, the structural organization of interstitial spaces and vessels of the ciliary body of the human eye (n = 5) were studied. The ciliary body was found to contain wide interstitial spaces--tissue clefts bound by collagen fibers and fibroblasts. Organ-specific lymphatic capillaries were also demonstrated in the ciliary body. According to the present findings and the lymphatic region concept, the first 2 elements of the lymphatic region of the eye were described: tissue clefts--prelymphatics and lymphatic capillaries of the ciliary body. The third element of the lymphatic region are the lymph nodes of the head and neck.
