PURPOSE. To study the changes in structural and hemodynamic parameters of the retina and foveolar avascular zone (FAZ) over time in patients with primary open-angle glaucoma (POAG) and diabetes mellitus (DM) observed in long-term follow-up.MATERIALS AND METHODS. The study included 258 patients (258 eyes) divided into five groups: group 1 — 58 patients (58 eyes) with stage I POAG and DM; group 2 — 50 patients (50 eyes) with stage I POAG; group 3 — 50 patients (50 eyes) with stage III POAG and DM; group 4 — 50 patients (50 eyes) with stage III POAG; group 5 — 50 patients (50 eyes) with DM. Patients underwent comprehensive ophthalmological examination, spectral domain optical coherence tomography (SD-OCT), optical coherence tomo-graphy angiography (OCT-A) of the macular region. The follow-up lasted 24 months.RESULTS. Analysis of the initial parameters in groups of patients with comorbidities showed the lowest values compared to controls, which were progressively worsening. MD in the group with DM + stage I POAG had reliably decreased after 12 months (by 5.05%), after 24 months by 12.12% (p≤0.05). The speed of GCL+IPL loss in groups 1 and 3 during the first year of observation was almost equal for initial and advanced glaucoma — 1.35 (-2.03%) and 1.32 (-2.36%) µm/year, but in group 3 the loss had doubled after two years (2.48 (-4.44%) and 1.41 (2.12%) µm/year). Deterioration of hymodynamic parameters in the macular region in groups 1 and 3 was noted primarily in the inner sectors (whole image vessel density in parafovea (PF wiVD) -0.79% during the first, and -2.57% during the second year in initial glaucoma, -0.6% and -1.24% in advanced, whole image vessel density in parafovea (PF wiVD) -0.2% and -1.22%, -0.66% and -1.56%, respectively). Parameters of FAZ had changed significantly after 2 years in patients with stage I POAG and DM: its area size had increased by 10.2%, perimeter by 4.49%, circularity index had decreased by 3.17%.CONCLUSION. Comorbidity of POAG and DM is accompanied by development and quick progression of significant changes in structural and hemodynamic parameters of the retina as observed by this long-term follow-up.

Purpose: to evaluate the immediate and long-term hypotensive efficacy, the number of complications, and the clinical benefits of a draining autovalve limbosclerectomy (DALS) performed using a kit of disposable instruments in patients with POAG of various stages in comparison with trabeculectomy (TE).Patients and Methods. The study is based on the analysis of the clinical and functional condition of 127 eyes of 127 patients with primary open-angle glaucoma (stage I POAG was detected in 2 eyes, stage II in 30 eyes, stage III in 88 eyes and stage IV in 7 eyes). Patients were divided into groups: the main group—76 people who underwent DALS using a set of disposable instruments, and the control group—51 people who underwent TE. The average age of patients is 68.9 ± 10.3 years. Before and within 24 months after surgery, all patients underwent standard diagnostic examinations. The initial level of IOP against the background of the maximum antihypertensive mode varied from 24 to 50 mm. Hg. According to gonioscopy, the angle of the anterior chamber was open in all cases (III–IV degree). Patient exclusion criteria: history of laser or surgical treatment of glaucoma, cataract treatment.Results. After 24 months of follow-up after DALS, the level of IOP in patients with stage I–II of POAG was 14.19 ± 1.83 mm Hg and with III–IV stage of POAG 14.95 ± 2.15 mm Hg, compensation was achieved in 88.2 % of patients without the use of antihypertensive drops. After TE, compensation was received in 72.6 % of patients, the IOP level was 16.9 ± 2.21 and 17.78 ± 2.31 mm Hg. respectively (p < 0.01). After DALS surgery, a decrease in the number of complications was revealed in comparison with TE: a decrease in сiliochoroidal detachment by 9.1 %, hyphema by 2.5 %, ophthalmic hypertension in the early p/o period by 3.2 %, cystic changes in the filtering bleb by 7.1 %.Conclusion. The standardized DALS operation using a disposable tool kit is a new highly effective and safe method for the surgical treatment of glaucoma. DALS may be the operation of choice in the treatment of POAG of all stages.

Purpose: to study the long-term changes of functional, structural, and hemodynamic parameters of the optic nerve in primary open-angle glaucoma (POAG) accompanied by diabetes mellitus (DM).Material and methods. The study involved 258 patients (258 eyes), which were divided into five groups: 1st group — 58 patients with stage I POAG and DM; 2nd group — 50 patients (50 eyes) with stage I POAG; 3rd — 50 patients with stage III POAG and DM; 4th — 50 patients with stage III POAG; 5th — 50 patients with DM. In addition to a complete ophthalmological examination, the patients underwent spectral optical coherence tomography (OCT), OCT angiography of the optic nerve head and macula. The observation period was 24 months.Results. The worst decrease in maximally corrected visual acuity was noted in patients with DM + POAG (groups 1 and 3): in 1 year of observation — stage I — 10.29%, stage III — 7.32 %, in control groups with isolated POAG stages I and III, 1.15 and 2.04%, respectively, in patients with DM, 1.39%; in 2nd year — 14.71 and 14.63% with a comorbid course of the disease and 1.15 and 4.08% in the absence of DM, respectively. The MD index in the group DM + POAG stage I after 12 months was significantly lower compared to patients with stage I POAG (by 5.05%), after 24 months by 12.12, 0.34 and 1.69%, respectively (p £ 0.05). The groups of comorbid patients showed lower average thickness levels of the retinal nerve fibers layer than in the control groups: 78.81 ± 11.39 μm at stage I and 63.08 ± 10.32 μm at stage III. A similar pattern was noted for the thickness of the neuroretinal rim and its areas as well indicators of the optic disc excavation (volume and c/d ratio).No significant difference was noted in the density of the optic nerve disc perfusion in stages I and III POAG with DM against the respective control groups during the first visit, but we noted a significantly lower vascular density in patients with the initial stage of POAG and DM (0.39 ± 0.04 / mm) than in patients with isolated glaucoma (0.42 ± 0.03 / mm). As the disease progressed, there was a further significant decrease in the average indicators of optic nerve disc perfusion and vascular density (group 3: 39.17 ± 3.43% and 0.33 ± 0.03 / mm).Conclusion. The study of the changes of visual, functional, structural and hemodynamic parameters of the optic nerve showed a faster rate of progression of glaucomatous optic neuropathy if accompanied with DM.

The goal of our work was to study the safety profile and effectiveness of a domestically manufactured shunting device for the treatment of advanced stage primary open-angle glaucoma. This article describes the surgical technique of “Anti-Glaucoma Implant A3” implantation, as well as long term follow-up results obtained from 19 patients (20 eyes). Materials and methods. The devices were implanted in 19 patients (20 eyes) with advanced stage primary open-angle glaucoma. The diagnosis was made based on collected medical history, results of objective and instrumental test findings. All patients included in the study underwent a standard ophthalmologic examination, including: automatic refractometry, best-corrected visual acuity (BCVA) assessment, automated static perimetry, biomicroscopy of the anterior segment, indirect ophthalmoscopy with an aspheric lens, gonioscopy. Optical coherence tomography (OCT) was used to assess retinal nerve fiber layer (RNFL) thickness. Conclusion. Intraocular pressure (IOP) lowering surgical procedures using an anti-glaucoma shunting device are non-inferior by their effectiveness to trabeculectomy, and have lower complication rate.

Purpose. To report the long-term follow-up results in patients with cataract and primary open-angle glaucoma (POAG) randomly assigned to cataract surgery combined with micro-bypass stent implantation or phacoemulsification alone.Methods. 36 subjects with cataract and POAG were randomized in a 1 : 2 ratio to either iStent implantation and cataract surgery (combined group) or cataract surgery alone (control group). 24 subjects agreed to be evaluated again 48 months after surgery. Patients returned one month later for unmedicated washout assessment.Results. At the long-term follow-up visit we reported a mean IOP of 15,9 ± 2,3 mmHg in the iStent group and 17 ± 2,5 mmHg in the control group (p=NS). After washout, a 14,2% between group difference in favour of the combined group was statistically significant (p=0,02) for mean IOP reduction. A significant reduction in the mean number of medications was observed in both groups compared to baseline values (p=0,005in the combined group andp=0,01in the control group).Conclusion. Patients in the combined group maintained low IOP levels after long-term follow-up. Cataract surgery alone showed a loss of efficacy in controlling IOP over time. Both treatments reduced the number of ocular hypotensive medications prescribed. This trial is registered with:NCT00847158.
