To investigate the possibility of conducting controlled laser coagulation of the retina using the feedback principle based on automated video monitoring. Material and methods. The developed automated system of laser coagulation of the retina with feedback has been tested on the fundus model in vitroand in vivoon the eyes of rabbits. The uniformity of coagulates in brightness and the required time of coagulate formation for the selected laser exposure modes were investigated. Results. On the fundus model and on the eyes of rabbits at a laser radiation power of 100, 140, 200 and 300 mW at each of the tested brightness levels in the range of 5–70% of the background value, uniform burns in brightness (coefficient of variation less than 10%) were obtained. The duration of the coagulate formation in automatic mode directly depended on the laser power: at a power of 200 and 300 mW, it did not exceed 0.3 s, at a power of 100 mW and a given brightness, it exceeded 1 s by more than 50%. With a power of 200 and 300 mW, the actual brightness was greater than planned in the range of 5–15% of the background level. With a power of 140 mW, there was no difference between the actual and planned brightness, and the duration of coagulate formation did not exceed 0.6 s with a burn brightness of 70% of the background. Conclusion. The new automated system of laser coagulation of the retina with feedback has great potential for development and implementation in clinical practice, allowing to carry out laser exposure on the fundus in vitroand in vivoto obtain reproducible threshold and near-threshold effects.

To evaluate a two-stage approach to surgical treatment of patients with cataract and primary open-angle glaucoma based on micropulse transscleral cyclophotocoagulation (MP-TSCPC) and phacoemulsification. Material and methods. The results of surgical treatment of 34 patients with cataract and primary open-angle glaucoma with non-dispersed intraocular pressure (IOP) were analyzed. A safer sequential surgery was chosen: at the first stage, MP-TSCPC was performed, at the second – cataract phacoemulsification. Results. After MP-TSCPC, the hypotensive effect was achieved in all 34 patients: IOP at the moderate stage was 14.6±1,4 mm Hg, at the advanced stage – 15.8±2,2 mm Hg. 1 month after surgery. Carrying out the second stage – phacoemulsification of cataracts 2–4 weeks after MP-TSCPC allowed to avoid reactive hypertension and achieve high functional results. IOP from the first day was 13.8±1,0 mm Hg in patients with moderate stage and 14.9±3,1 mm Hg in patients with advanced stage and remained compensated for 3 months after surgery. Visual acuity 3 months after surgery was 0.85±0.05 in patients with moderate and 0.73±0.05 with advanced stage. Anti-inflammatory prevention based on 0.1% fluorometholone acetate solution, considering the minimal effect on the IOP of the operated eye, showed promising advantages over other glucocorticoids for patients with glaucoma and cataracts.

Radiation retinopathy and maculopathy are the most common causes of visual impairment in patients with uveal melanoma treated with plaque radiotherapy. There are no standards of medical care for such patients, and various therapeutic methods of treatment are limited by rather poor results. The use of vascular endothelial growth factor inhibitors is proposed worldwide to improve visual acuity or stabilize one's with the development of post-radiation retinopathy, even though today the use of such methods is «off label». Purpose. To analyze the development of radiation maculopathy in patients with uveal melanoma treated with plaque radiotherapy and its intravitreal anti–vascular endothelial growth factor treatment. Material and methods. To perform the review, a search was carried out for literature sources on the Pubmed and Scopus reference databases for the period up to 2022 inclusive using the following keywords: «uveal melanoma», «radiation maculopathy», «anti-vascular endothelial growth factor», «plaque therapy complications». A total of 39 articles related to the review topic were selected. Results. It can be concluded that intravitreal anti-vascular endothelial growth factor treatment of uveal melanoma shows its effectiveness in reducing the height of macular edema and in improving visual acuity.

To evaluate postoperative vault parameters – from the posterior surface of the phakic posterior intraocular lens (PIOL) to the anterior surface of the lens, its correlation with the preoperative data study and the choice of the PIOL size. Material and methods. This research was based on the retrospective analysis of 128 eyes (64 patients) for the period from February 2019 to May 2021. The age of patients varied from 21.0 to 42.0 29.5±5.5 (mean 29.5±5.5) years. All patients underwent PIOL implantation with Staar EVO Visian ICL (V4C) PIOL. The follow-up period ranged between 3 to 24 months. Associations between the postoperative vault and age, ICL size, spherical equivalent (SE), axial length (AL), anterior chamber depth (ACD), white-to-white (WTW) were investigated using Spearman's correlation analysis and stepwise multiple regression analysis. Accepted confidence level p<0.05. Results. The mean values of the vault were from 142 to 1340µm (576,56±245,77µm). Statistical analysis revealed that the postoperative vault height had a moderate correlation with WTW, IOL size and ACD (anterior chamber depth). There was no significant correlation with age, spherical equivalent, axial length. There was a strong correlation between PIOL's size and WTW, and a significant correlation with ACD. Stepwise multiple regression showed that ICL size, anterior chamber depth, WTW were significant factors associated with postoperative vault (adjusted R²S 0.359). Conclusion. The assessment of the size of the postoperative vault and its dependence on the data of the preoperative study showed that the size of the PIOL and the depth of the anterior chamber have the greatest influence on the formation of the postoperative vault. Optimal postoperative vault was achieved in 86% cases. In conclusion, the currently existing method for PIOL sizing does not always yield ideal vault.

To analyze the success of using prisms in conjugate horizontal gaze paresis compared to other treatment methods. Material and methods. The study involved 30 patients with conjugate horizontal gaze paresis. The average age of patients at the time of treatment was 57.8±6.68 years. The average period of clinical follow-up for strabismus symptoms in patients after the appropriate treatment was 12.6±3.8 months. The patients were divided into two groups: the first group (main group) of 15 patients who underwent prismatic correction in combination with etiopathogenetic treatment and 15 patients (control group) who underwent etiopathogenetic treatment without prismatic correction. Results. The treatment results were evaluated according to three criteria: absence of abnormal head posture (AHP) and diplopia, as well as elimination of esotropia. Based on our data, the AHP angle did not reveal statistically significant difference at the stage before treatment (p=0.999), however, during treatment in the first group (using prismatic correction), it was 4.4 times less than in the second group (p<0.001).

To evaluate long term cornea characteristics after Nd:YAG laser destruction of epithelial ingrowth in patients after Femto-LASIK and ReLEx Smile and assess its safety according to the state of the corneal endothelium. Material and methods. Due to the rather rare development of this condition, clinical material is presented by 6 cases (6 eyes): 4 men and 2 women aged 22 to 43 years, average 34.6±2.7 years. The average degree of myopia is –4.75 diopters. The Femto-LASIK technique was performed in 3 eyes, and ReLEx Smile – in 3 eyes. All surgeries were carried out without complications, the patients were discharged at the place of residence with the usual recommendations. The timing of epithelial ingrowth after refractive surgery varied from one week to 3 months. The number of sessions of Nd:YAG laser destruction varied regardless of the type of epithelial ingrowth and the technique of previous refractive surgery. The safety of the treatment was confirmed by studying the state of the corneal endothelium of the operated patients. Results. In all 6 cases, it was possible to achieve complete destruction of the zones of epithelial ingrown. Epithelial ingrowth was eliminated at one patient in 5 sessions, at two – in 3 sessions, at two – in 2 sessions and at one – in one session. The number of sessions and the number of impulses in different patients varied greatly and it was not possible to draw a direct parallel between the volume of epithelial ingrown and the total number of impulses.

The reasons of decreased outflow of intraocular fluid of drainage and embedded (uveoscleral) pathways, lead to the increase of intraocular pressure in neoplastic glaucoma and depend on the type of eye tumor, its localization and size. This determines the necessity for a differentiated approach to the treatment of patients with secondary glaucoma and the development of pathogenetically oriented methods of treatment. Conclusion. Almost all of the intraocular tumors can potentially lead to increase of intraocular pressure. The pathomechanisms of neoplastic glaucoma are very diverse, but the leading ones are blocking of the anterior chamber angle drainage zone by tumor, neovascularization of the anterior chamber angle structures and anterior iris-lens diaphragm displacement. In all cases, the increase in intraocular pressure is associated with the violation of aqueous humor outflow through the main drainage paths of the eye.
