Aim. To assess the effectiveness of combined non-penetrating surgery: non-penetrating deep sclerectomy and ab externo trabeculectomy in patients with primary open-angle glaucoma depending on type of aqueous humor retention. Methods. Results of surgeries on 72 patients (83 eyes) with primary open-angle glaucoma were analyzed. Patients were divided into 2 groups. Standard ophthalmic examination was added by fluorescein lymphography of the anterior eye to determine the surgery type as well as for hypotensive effect long-term prognosis. Non-penetrating deep sclerectomy and ab externo trabeculectomy were conducted in the first group (67 eyes). In the control group (16 eyes) standard non-penetrating deep sclerectomy was performed. A cytostatic was used as a subconjunctival injections in the post-surgical period. Results. Intraocular pressure was fully compensated in 52 eyes out of 67 (77.6%) in the long-term period after non-penetrating deep sclerectomy and ab externo trabeculectomy in the first group. In 15 eyes (22.4%) topical hypotensive drugs were required for complete compensation of intraocular pressure. Complete compensation of intraocular pressure was registered in patients with moderate aqueous humor flow reduction (trabecular and mixed with prevalence of trabecular forms). Topical hypotensive drugs were required in severe aqueous humor flow reduction (mixed form with prevalence of intrascleral). In the second group, compensation of intraocular pressure was achieved only in early post-surgical period in 12 eyes (75%) with further decrease of hypotensive effect after 4-6 months. There was no complete compensation of intraocular pressure at late post-surgical period. To normalize the intraocular pressure, topical hypotensive drugs were required in 15 eyes (93.8%), surgery was repeated in 1 (6.2%) case. Conclusion. Combined surgery (non-penetrating deep sclerectomy and ab externo trabeculectomy) is more effective compared to non-penetrating deep sclerectomy and is indicated in patients with open-angle glaucoma and moderate aqueous humor flow reduction.

Purpose. Analysis of the effectiveness of surgical treatment of patients with primary open-angle glaucoma associated with cataract the first stage realization of cataract phacoemulsification with IOL implantation (PHACO), and the second stage - microinvasive nonpenetrating deep sclerectomy (MNPDS). Material and methods. The results of 234 cases of performing PHACO and MNPDS at various stages have been analyzed. The main group included patients who underwent PHACO, followed by MNPDS – 39 persons, 40 eyes. The group was divided into a subgroup based on the date of the second intervention. 1 subgroup – patients who underwent MNPDS 1 month after PHACO (11 cases); 2 subgroup – 3 months after PHACO (29 cases). The control group included patients who underwent MNPDS followed by PHACO – 180 persons, 195 eyes. Also, subgroups of patients were identified for whom PHACO + IOL was performed in the second stage after 1 month – 1 subgroup (99 cases) and after 3 months – 2 subgroup (96 cases). Results. Patients of the main group showed a significant decrease in intraocular pressure after each stage of treatment. in the control group, intraocular pressure decreased after the first stage of treatment, but increased 6 months after surgery. Conclusions. According to the study, in primary open-angle glaucoma associated with cataract, the most persistent hypotensive effect is observed when the first stage of cataract phacoemulsification is performed, and the second stage is antiglaucoma surgical intervention. Key words: glaucoma, cataract, cataract phacoemulsification, microinvasive nonpenetrating deep sclerectomy.

Purpose. Evaluation of the efficacy of descemethogoniopuncture (DGP) at various times after microinvasive non-penetrating deep sclerectomy (MNPDS) in patients with glaucoma. Material and methods. The analysis of the results of DGP in 64 eyes of patients with primary open-angle glaucoma after previously performed MNPDS. According to the timing of DGP after MNPDS, the patients were divided into 3 groups. In the 1st group BPH was performed after 1–2 months (22 eyes), the 2nd group – after 3–4 months (21 eyes), the 3rd group after 5–6 months (21 eyes). The follow-up period was 1 year. Results. The level of intraocular pressure before DGP averaged 15.1±0.6 mm Hg in group 1, 17.5±0.9 mm Hg in group 2, and group – 18.6±0.7 mm Hg. After DGP, 13.1±0.4 mm Hg, 14.6±0.7 mm Hg, 16.1±0.5 mm Hg respectively. According to ultrasound biomicroscopy, the highest and extended intrascleral cavities and tunnels, as well as a thin loose trabeculodescemet membrane (TDM), were observed in the eyes of the 1st group. With an increase in the time after MNPDS, there was a compaction of TDM, a decrease in the height and length of the intrascleral cavity and tunnels. 12 months after DGP, the most pronounced antihypertensive effect without antihypertensive therapy occurred in group 1 – 55% of cases compared with groups 2 and 3 (33% and 14% respectively). Conclusion. The greatest efficiency was shown by performing DGP within 1–2 months after MNPDS, which is associated with the minimum development of proliferative processes in the intrascleral outflow tract in the early stages after this operation. Key words: descemethogoniopuncture, microinvasive non-penetrating deep sclerectomy, intraocular pressure, hypotensive effect, glaucoma.

BACKGROUND: Glaucoma remains one of the current problems of modern ophthalmology. The combination of glaucoma and cataract is observed in 1738.6% of cases, and glaucoma with pseudoexfoliative syndrome in 2050% of primary open-angle glaucoma cases. AIM: The aim of this work is to develop an effective and safe technology of complex energetic surgical treatment of the incipient primary open-angle glaucoma stage and cataract on the background of pseudoexfoliation syndrome on the basis of modified laser, hydrodynamic and ultrasound methods use. MATERIALS AND METHODS: 187 patients (187 eyes) with the incipient stage of primary open-angle glaucoma, cataract and pseudoexfoliation syndrome were examined. In the main group (111 eyes), selective laser trabeculoplasty followed by femtosecond laser-assisted cataract surgery with hydrodynamic trabeculocleaning was performed. Patients in the control group (76 eyes), after selective laser trabeculoplasty, underwent phacoemulsification according to the standard technique. RESULTS: The developed technology allowed to reach the hypotensive effect in 35.2% (t=23.0; р 0.001) of baseline intraocular pressure values, of individual intraocular pressure level without adding IOP-lowering medications in 27% of cases, stabilization of visual functions and morphometric indices of the optic disc during 2 years of follow-up in 97.3% of cases unlike the selective laser trabeculoplasty with subsequent phacoemulsification (21.2, 5.3 and 81.6% respectively). The patients of the main group had significantly lower energy expenditure during the stage of phacoemulsification, a lower percentage of postoperative inflammatory reaction was noted, and a persistent hypotensive effect with stabilization of visual functions was achieved based on the results of a two-year follow-up. CONCLUSIONS: Femtosecond laser-assisted phacoemulsification, performed as part of complex treatment in patients with cataract and incipient stage of primary open-angle glaucoma, is a sparing method that minimizes surgical trauma and achieves a persistent hypotensive effect, reduces intraocular pressure to an individual level and stabilizes visual functions in 97.3% of cases.

Purpose: To determine the role that progressive spectacle lenses play in intraocular pressure compensation and stabilization of the glaucomatous process in patients with primary open-angle glaucoma (POAG) combined with presbyopia and refractive errors. Material and methods. 29 patients (53 eyes) aged 43 to 67 years with I-II stage POAG and a certain type of refractive error were enrolled into study. All patients had intraocular pressure (IOP) compensated to the target level on medication. Patients of the main group (17 people, 32 eyes) used universal progressive spectacle lenses with optimized surface. The patients of the control group (12 people, 21 eyes) used separate monofocal glasses for near and distance vision as a method of ametropia correction. Visual acuity test, refractometry, pneumotonometry, tonography, automated static perimetry were applied for monitoring the patients. The measurements were taken before spectacle correction and a year after its prescription. Results. A decrease of IOP (p=0.01) and an increase of the aqueous humor outflow coefficient (p<0.01) were determined after one year use of the recommended type of vision correction in the main group, whereas in the control group there was an increased level of IOP (p<0.05) and a reduced aqueous humor outflow coefficient (p<0.2). Conclusion. The use of progressive spectacle lenses as a method of permanent vision correction reliably reduces IOP and improves the aqueous humor outflow in patients with early-stage POAG. The absence of negative visual field dynamics indicates the stabilization of the glaucomatous process.

The Difference

Hypotensive effect of endotrabeculectomy was compared with that of selective laser trabeculoplasty in patients with primary open-angle glaucoma (POAG). We evaluated 44 patients (44 eyes) with POAG. In the first group (23 patients), endotrabeculectomy (trabecular ablation through the angle of anterior chamber) was performed, and in the second group (21 patients) the patients underwent selective laser trabeculoplasty. When comparing the intraocular pressure (IOP), it was found that the difference between preoperative and postoperative IOP was significant up to 6 months of follow-up in both groups (p < 0.05), however, hypotensive effect in the first group was more pronounced (7.58 vs. 1.55 mmHg, respectively). When comparing the number of hypotensive medications used before and after glaucoma surgery, it was found that the difference in patients of the first group was significant throughout the observation period (p = 0.028), while in patients of the second group there was no significant difference from the 3rd month of observation. The number of topical drugs to reduce IOP decreased by 1.44 in the first group (p < 0.05) and by 0.33 in the second group (p = 0.109). Endotrabeculectomy, as well as selective laser trabeculoplasty, showed significant hypotensive effect in patients with POAG within 6 months of observation, however, hypotensive effect of endotrabeculectomy significantly overweighted that of SLT. Keywords: endotrabeculectomy, selective laser trabeculoplasty, intraocular pressure, primary open-angle glaucoma.

The problem of the reproduced (generic) and original (branded) medications coexistence on the pharmaceutical market is very relevant for Russia. Numerous polls have shown that very few among patients and even doctors clearly understand the differences between original drugs and generics, nor they know how these drugs are produced, and what advantages and weaknesses they have. Aim. This paper covers the study of Trilactan (0.005% latanoprost, Solopharm, Russia) use in patients with different stages of primary open-angle glaucoma, and includes the analysis of the hypotensive effect and adverse events rate. Material and methods. The study included 47 patients divided into 3 groups. The first group included 17 treatment-naïve patients (32 eyes). The second group included 14 patients (28 eyes) previously treated with latanoprost 0.005% once a day in the evening at least for a month. The third group consisted of 16 patients (32 eyes) treated with beta-blockers or carbonic anhydrase inhibitors, in whom the target level of intraocular pressure had not been reached. All patients received 1 drop of Trilactan every evening; the observation lasted for 3 months. Conclusions. The treatment was well tolerated. The intraocular pressure decrease was observed in all cases (p > 0.05). Local and systemic adverse events under Trilactan treatment did not differ from possible side effects typical to the drugs of this pharmacological group in terms of its type and rate.

Purpose. To compare the effectiveness and safety of carbon dioxide (CO2) laser-assisted deep sclerectomy surgery (CLASS) and trabeculectomy (Trab) for treatment of primary open-angle glaucoma (POAG). Methods. In this retrospective and comparative study, 77 eyes of 62 patients with POAG were studied and divided into the CLASS and Trab groups. The best-corrected visual acuity (BCVA), intraocular pressure (IOP), number of medications, surgical success rate, and complications were analyzed. Results. The mean follow-up periods were 27.89 ± 2.94 months and 26.11 ± 2.06 months in the CLASS and Trab groups, respectively. 30 eyes (24 patients) underwent CLASS and 47 eyes (38 patients) underwent Trab. The BCVA in the CLASS and Trab groups was recovered to baseline at postoperative 1 week and 1 month, respectively. At last follow-up visits, a remarkable reduction in the IOP and number of medications was observed in both groups, and no significant difference was found in those between the two groups. The complete success rates were 51.7% and 47.7% in postoperative 24 months in the CLASS and Trab groups, respectively ( P > 0.05 ). There were higher rates of delayed anterior chamber formation (21.3%) and thin-wall filtrating blebs (10.6%) in the Trab group. Meanwhile, the peripheral anterior synechiae were only observed in the CLASS group, and the ratio was 30%. Conclusions. CLASS is an effective and safe treatment modality for POAG, with fewer filtering bleb-related complications and quicker visual recovery in the early postoperative stage than trabeculectomy. The efficacy of lowering intraocular pressure was similar for both procedures.
