Objective: To investigate the changes in macular retinal layers and panretinal neuroretinal functions in the long-term follow-up of patients with primary open-angle glaucoma. Materials and Methods: Forty-one patients diagnosed with primary open-angle glaucoma were followed up for 12 months. According to their mean deviation (MD) values), the patients were put into two groups as Group 1 with early stage glaucoma (MD≥-6) and Group 2 with middle-advanced stage glaucoma (MD<-6). Optical coherence tomography (OCT) and multifocal electroretinography (mfERG) were performed at the baseline and at the sixth- and 12th-month evaluations. The OCT, retinal layer and mfERG findings were compared between the two groups. Results: There was no statistically significant difference between the groups in terms of gender and age In Group 2, the mean baseline macula Retina Nerve Fiber Layer, Ganglion Cell Layer and Inner Pleksiform Layer measurements were lower in each quadrant compared to Group 1. Concerning progression in OCT measurements, there was no significant difference between the two groups. However, it was noteworthy that in Group 2, there was a decrease especially in the first and second ring amplitudes of the P1 and N2 waves and prolongation of the implicit time. At the 12-month evaluation, there was prolongation of the implicit time of the N1 wave and a decrease in the P1 wave amplitude in Group 1. Conclusion: Retinal layers are affected in patients with intermediate and advanced stage glaucoma. In the follow-up of early stage glaucoma patients, mfERG measurements can show damage that may occur.

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.

Purpose. To evaluate the efficacy and safety of femtolaser-assisted phacoemulsification in glaucomatous eyes in the long-term follow-up. Materials and methods. A retrospective analysis of the results of the surgical treatment of patients with combined cataract and glaucoma pathology was analyzed. The patients were divided into groups depending on the method of surgical intervention: 1) phacoemulsification with femtolaser support (26 eyes, 23 patients); 2) phacoemulsification (36 eyes, 30 patients); Results. Before surgery, there were no statistically significant differences in IOP and corneal hysteresis (СН) between groups 1 and 2. The mean values of IOP cc, IOP g and СН of group 1 before surgery were 22.7±6.1 mm Hg, 20.9±6.9 mm Hg, 8.5±1.6 mm Hg; 2 group – 22.9±8.7 mm Hg, 21.6±8.9 mm Hg, 8.9±1.6 mm Hg respectively. Average values of IOP cc, IOP g and CН 5 years after the surgical treatment in group 1 were 15.3±1.2 mm Hg, 14.4±3.4 mm Hg, 9.6±4.2 mm Hg; in group 2 – 18.0±4.2 mm Hg, 16.1±4.2 mm Hg, 8.8±2.2 mm Hg respectively. In both groups, stabilization of IOP and CH indices was noted, which remained throughout the entire observation period, which shows the normalization of the biomechanical properties of the corneoscleral membrane of the eye in the long-term postoperative period. Conclusion. Femtolaser accompaniment of phacoemulsification is an effective and safe method of cataract surgery for combined pathology. Key words: femtolaser, cataract, glaucoma, phacoemulsification.

Mitral regurgitation due to bileaflet prolapse and ischemic causes can be difficult to repair. Midterm experience of the Alfieri edge-to-edge repair as an alternative to valve replacement is reported. Twenty-six patients with severe mitral regurgitation underwent the Alfieri repair between January 1998 and December 2000 (group 1); 15 cases were due to bileaflet prolapse and 7 were of ischemic origin. During the same period, valve replacement was performed in 36 patients (group 2), 20 of whom had similar indications. Follow-up was complete to a mean of 15 months (range, 1–28 months). There was no early death in either group. During follow-up, there was no reoperation in group 1, while 2 patients in group 2 required reoperations due to prosthetic valve endocarditis. There were 4 major thromboembolic or bleeding events in group 2, and none in group 1. All patients in group 1 had trivial to mild mitral regurgitation on follow-up echocardiography. The mean mitral valve gradient was significantly higher in group 2 compared to group 1 (7.2 versus 3.2 mm Hg, p = 0.001). The edge-to-edge repair is associated with good early and midterm results. Long-term follow-up is required to evaluate the durability of this technique.

Objective: Multinodular goiter is a common surgical disease. There is no common consensus regarding the extent of thyroidectomy for multinodular goiter. This  study aims to present personal experience on treating patients with multinodular goiter and to compare complication rates and results of total and partial thyroidectomy for multinodular goiter. Material and Method: Three hundred fifty patients underwent thyroidectomy for multinodular goiter between May 2003 and October 2010. All patients were diagnosed as multinodular goiter and were referred to surgery by one endocrinologist. All operations were also performed by one surgeon using microsurgical techniques. Partial thyroidectomy (bilateral subtotal or unilateral total thyroidectomy and contralateral subtotal thyroidectomy) was performed in 65 patients (Group-1) and extracapsular total thyroidectomy was performed in 285 patients (Group-2). All patients are being followed followed from the day they were diagnosed until now by the same endocrinologist. Fisher exact test was used for statistical analysis. Results: In Group-1, one patient had transient vocal-cord palsy and but none had hypoparathyroidism. On the other hand, in Group-2, two patients had transient vocal-cord palsy, five had hypocalcemia (one was permanent), and one had a hematoma. Mortality and wound infection were absent in both groups. The histopathological studies showed that 40 incidental thyroid carcinomas occurred among Group-2 patients. During long-term follow-up, 13 patients had goiter recurrence (n = 65, 20%) in Group-1, whereas none had goiter recurrence in Group-2. Conclusion: There were no statistically significant differences in the complication rate between subtotal and total thyroidectomy groups (p>0.05). However, the recurrence rate was higher (statistically significant) after subtotal thyroidectomy than after total thyroidectomy (p<0.05). Total thyroidectomy eliminated future recurrence of the disease and is also curative in incidental thyroid carcinomas. In addition, it can be safely performed using microsurgical techniques.

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 of the study. Comparison of hospital and long-term results of autoarterial reconstruction of carotid artery bifurcation and the formation of a new bifurcation with an extended atherosclerotic lesion of the internal carotid artery (ICA). Materials and methods. In the period from January 2018 to May 2020, this cohort, comparative, prospective, open-label study included 279 patients with an extended atherosclerotic lesion of the ICA operated on in the Alexandr Hospital. Depending on the implemented strategy of surgical correction, all patients were divided into two groups: group 1 (n=132) — autoarterial reconstruction of bifurcation of the carotid arteries; Group 2 (n=147) — the formation of a new bifurcation. Complications were recorded in the hospital and long-term postoperative periods. The total follow-up period was 16.4±9.3 months. The endpoints of the study were such adverse cardiovascular events as death, myocardial infarction (MI), stroke, thrombosis / restenosis of the anastomosis zone, combined endpoint (death from stroke / IM + IM + stroke). Results. The ICA clamping time in group 1 was 32.6±3.3 minutes, in group 2 – 31.7±3.5 minutes, which did not receive statistically significant differences (р=0.81). In the hospital postoperative period, adverse cardiovascular events were not recorded. In the long-term follow-up, the groups were comparable in the frequency of all complications. Identified lethal outcomes developed as a result of the formation of MI in patients with multiple lesions of the coronary arteries and a history of myocardial revascularization. The likely cause was shunt / stent thrombosis with subsequent coronary insufficiency and an increase in ischemic heart damage. The causes of stroke, recorded in each group in isolated cases, were the presence of atrial fibrillation. Patients did not comply with the recommended regimen of anticoagulant therapy, which provoked the development of cerebral catastrophe. In turn, the identified restenoses of the reconstruction zone were asymptomatic and were also observed in isolated cases in each group in the period 12 months after CEE. Conclusion. Autoarterial reconstruction of carotid bifurcation and the formation of a new bifurcation are comparable in safety and effectiveness methods of surgical treatment of an extended atherosclerotic lesion of the ICA. Operation techniques differ in the choice of an artery that is cut off from bifurcation — the external carotid artery or ICA. Further, the reconstruction progress is absolutely identical. Hospital and long-term follow-up results showed minimal indicators of the development of cardiovascular and hemodynamic changes due to the type of operation. Thus, both reconstruction techniques can be the operation of choice for an extended ICA lesion.

Aim. To analyze the immediate and long-term outcomes of eversion and conventional carotid endarterectomy (CE) with patch angioplasty.Material and methods. For the period from February 1, 2006 to September 1, 2021, the present retrospective multicenter open comparative study included 25106 patients who underwent CE. Depending on the technique of operation, the following groups were formed: group 1 (n=18362) — eversion CE; group 2 (n=6744) — conventional CE with patch angioplasty. The long-term follow-up period was 124,7±53,8 months.Results. In the hospital postoperative period, the groups were comparable in incidence of all complications: lethal outcome (group 1: 0,19%, n=36; group 2: 0,17%, n=12; p=0,89; odds ratio (OR) =1,1; 95% confidence interval (CI) =0,57- 2,11); myocardial infarction (MI) (group 1: 0,15%, n=28; group 2: 0,13%, n=9; p=0,87; OR=1,14; 95% CI=0,53-2,42); stroke (group 1: 0,33%, n=62; group 2: 0,4%, n=27; p=0,53; OR=0,84; 95% CI=0,53-1,32); bleeding with hematoma formation (group 1: 0,39%, n=73; group 2: 0,41%, n=28; p=0,93; OR=0,95; 95% CI=0,61-1,48); internal carotid artery (ICA) thrombosis (group 1: 0,05%, n=11; group 2: 0,07%, n=5, p=0,9; OR=0,8; 95% CI=0,28-2,32). In the long-term follow-up, the groups were comparable only in MI incidence: group 1: 0,56%, n=103; group 2: 0,66%, n=45; p=0,37; OR=0,84; 95% CI=0,59-1,19. All other complications were more frequent after conventional CE with patch angioplasty: all-cause death (group 1: 2,7%, n=492; group 2: 9,1%, n=616; p<0,0001; OR=0,27; 95% CI=0,24-0,3); lethal ischemic stroke (group 1: 1,0%, n=180; group 2: 5,5%, n=371; p<0,0001; OR=0,17; 95% CI=0,14-0,21); non-lethal ischemic stroke (group 1: 0,62%, n=114; group 2: 7,0%, n=472; p<0,0001; OR=0,08; 95% CI=0,06-0,1); ICA restenosis >60%, requiring re-revascularization (group 1: 1,6%, n=296; group 2: 12,6%, n=851; p<0,0001; OR=0,11; 95% CI=0,09-0,12). Thus, the composite endpoint (lethal ischemic stroke + non-lethal ischemic stroke + MI) after conventional CE with patch angioplasty was more than 6 times higher than this parameter of eversion CE: group 1: 2,2%, n=397; group 2: 13,2%, n=888; p<0,0001; OR=0,14; 95% CI=0,12-1,16.Conclusion. Conventional CE with patch angioplasty is not prefer for cerebral revascularization in the presence of hemodynamically significant ICA stenosis due to the high prevalence of deaths, stroke, and ICA restenosis in the long-term follow-up.

Purpose. To study the effectiveness of the developed partially fistulizing glaucoma surgery in the treatment of primary open-angle glaucoma (POAG) in combination with complicated cataract. Material and methods. 28 patients (28 eyes) were examined, including 13 patients (13 eyes) with I–III stages of POAG, operated according to the method of glaucoma surgery developed by us (group 1), and 15 patients (15 eyes) with a combination of previously unoperated glaucoma with incomplete complicated cataracts, who underwent a combined intervention – simultaneous phacoemulsification of cataracts with the specified variant of partially fistulizing glaucoma intervention (group 2). The analysis of the frequency of complications, the dynamics of visual functions, visual acuity and ophthalmotonus before surgery, at the time of discharge from the hospital, and in the longterm (6–9 months) after surgery was carried out. Results. In group 1, in the long term, the absolute hypotensive effect was recorded in 81.8% of cases, visual functions remained the same – in 90.9%. In group 2, by the end of follow – up, the level of normalized intraocular pressure was recorded in all patients, while in 78.6% of cases without drug correction and in 21.4% – with the help of antihypertensive drugs. Visual acuity in group 2, after a single-stage combined operation by the day of discharge from the hospital, averaged 0.53±0.05, in the long-term – 0.77±0.06, while the stabilization of glaucoma optic neuropathy after surgery occurred in 92.9%. Conclusion. Glaucoma surgery according to the proposed method in the studied long-term periods in patients with POAG provided a sufficiently high hypotensive effect and the preservation of visual functions. Combined single-stage intervention was an effective way to increase visual acuity, normalize ophthalmotonus and stabilize glaucoma optic neuropathy, as well as reduce drug load. Key words: primary open-angle glaucoma, cataract, partially fistulizing glaucoma surgery, cataract phacoemulsification.
