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.

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.

Abstract Background The short- and medium-term outcomes of iStent have been extensively studied; however, only few studies have investigated its long-term outcomes. Here, we assessed the long-term efficacy and safety of two iStents with concomitant cataract surgery in glaucomatous eyes while also evaluating measures of disease stability using visual field and optical coherence tomography (OCT) of the optic nerve and the macula throughout 8 years of follow-up. Methods This longitudinal, single-center consecutive case series included glaucomatous eyes that underwent implantation of two first-generation trabecular micro-bypass stents (iStent) with concomitant cataract surgery. Eight-year efficacy outcomes included mean intraocular pressure (IOP) and medications, as well as surgical success. Eight-year safety outcomes included best-corrected visual acuity (BCVA), visual field mean deviation (VF-MD), cup-to-disc ratio (CDR), retinal nerve fiber layer (RNFL) thickness, ganglion cell-inner plexiform layer (GC-IPL) thickness, and adverse events. Results A total of 62 eyes with primary open-angle glaucoma (POAG) were included. At 8 years postoperative, IOP reduced by 26% from 19.2 ± 3.9 mmHg preoperatively to 14.2 ± 2.4 mmHg (P < 0.001), 91.1% of eyes achieved IOP ≤ 18 mmHg (vs. 51.6% preoperatively), 69.6% of eyes achieved IOP ≤ 15 mmHg (vs. 14.5% preoperatively), and 25% of eyes achieved IOP ≤ 12 mmHg (vs. 1.6% preoperatively). Medication use decreased by 17.9% from 2.8 ± 1.1 preoperatively to 2.3 ± 1.2 (P = 0.018). Surgical success was 90%, as six eyes underwent subsequent glaucoma surgeries. Safety measures of BCVA, CDR, RNFL thickness and GC-IPL thickness remained stable through 8 years postoperative. VF-MD remained stable until postoperative year 5 and subsequently progressed according to the natural history of glaucomatous disease. Conclusions Implantation of two iStents with concomitant cataract surgery is an effective and safe treatment option for surgery-naïve POAG eyes, evidenced by significant IOP and medication reductions, reasonable surgical success, and favorable safety outcomes, throughout the 8-year follow-up. Our data additionally supports the efficacy of this combined procedure in stabilizing or slowing disease progression.

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.

Introduction. It has been recognized that cataract surgery leads to a reduction of intraocular pressure, both in healthy and in glaucoma patients. This prospective interventional clinical study aimed to investigate the effects of cataract surgery on intraocular pressure and its short- and long-term fluctuations in medically controlled primary open-angle glaucoma patients and non-glaucomatous patients. Material and Methods. Two groups of 31 patients (31 eyes) were studied. The observed group included patients with glaucoma and cataract, and the control group included patients with senile cataract only. The intraocular pressure was measured three times daily pre- and at 1, 3 and 6 months postoperatively. Results. In both groups, a significant postoperative reduction in both mean and maximum intraocular pressure. Six months after surgery, in the observed group the average and maximum intraocular pressure reduction levels were -2.73 ? 1.91 mmHg and -3.16 ? 2.19 mmHg, and -2.26 ? 1.71 mmHg and -2.53 ? 1.70 mmHg in the control group. In the observed group, at 3 and 6 months after surgery, a significant reduction in short-term fluctuations was observed. Six months after surgery, short-term fluctuations decreased by -1.04 ? 2.20 mmHg compared to preoperative. Postoperatively, in the observed group, long-term fluctuations of average and maximum intraocular pressure were 2.69 ? 2.15 mmHg and 2.88 ? 2.22 mmHg, respectively, and in the controls they were 2.02 ? 1.28 mmHg and 2.42 ? 1.47 mmHg, showing no significant differences between groups. Conclusion. In patients with primary open-angle glaucoma, cataract surgery results in a statistically significant reduction in both average and maximum intraocular pressure as well as of short-term fluctuations.

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 evaluate the long-term effectiveness of iTrack (Nova Eye Medical, Fremont, USA) ab-interno canaloplasty performed as a standalone procedure, or combined with cataract surgery, in reducing antiglaucoma medication dependence and maintaining intraocular pressure within target range in patients with controlled primary open-angle glaucoma. Methods: This is a retrospective, single-center, case series study of patients who underwent iTrack ab-interno canaloplasty as a standalone procedure ( n = 34) or in combination with cataract surgery ( n = 11). Eyes with controlled mild or moderate glaucoma (intraocular pressure ⩽17 mmHg) were included; those with prior glaucoma surgeries were excluded. The primary outcome was the mean reduction in glaucoma medication and the secondary outcome was the maintenance of controlled intraocular pressure postoperatively. Results: A total of 35 patients (45 eyes) with a mean age of 73 ± 9.7 years were included in the study. For all eyes, a significant decrease (61%) in the mean number of medications was seen at 36 months (1.89 ± 0.93 versus 0.60 ± 0.82; p < 0.001), with 56% (14/25) of eyes medication free. No significant difference was observed in the reduction of medication use whether iTrack was performed with or without cataract surgery at 12 and 36 months. Mean baseline intraocular pressure of 14.42 ± 2.2 mmHg for all eyes was maintained at the 12-, 24-, and 36-month follow-up visits (14.6 ± 3.65, 15.06 ± 2.26, and 14.19 ± 2.91, respectively), with no significant difference between the two groups ( p = 0.08). Conclusion: The iTrack ab-interno canaloplasty significantly reduced medication dependency and maintained intraocular pressure within target range in patients with controlled mild or moderate primary open-angle glaucoma, while showing a good safety profile, both as a standalone procedure or in combination with cataract surgery.
