Purpose: to determine the concentration of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinases-1 (TIMP-1) in the tear of patients with cornea melting and to assess whether these factors can be used as prognostically significant biomarkers of keratolysis. Material and methods. 20 patients who underwent urgent penetrating keratoplasty were tested for cornea perforation (melting) before and after the procedure. For control, 12 healthy adults (24 eyes) were tested. The tear fluid was collected before the surgery and on the 7th day after it with the help of filtering paper. MMP-9 and TIMP-1 concentrations were determined by ELISA. The course of the early postoperative period was assessed according to the area of keratotransplant epithelization on the 7th day after surgery. Results. MMP-9 and TIMP-1 concentrations in the tears of all patients before the surgery were significantly higher than the ones of healthy controls. The patients who were supposed to have re-keratoplasty had a significantly higher MMP-9 concentration than the ones who expected the first keratoplasty. An uncomplicated early postoperative period showed a statistically significant decrease of MMP-9 and TIMP-1 concentrations, whilst the complicated one demonstrated a significant increase of both markers. The highest increase of both markers was shown by the patients who underwent re-keratoplasty. Conclusion. MMP-9 concentration in the tears is a valid marker of the clinical course of the early post-keratoplasty period. To ensure a successful donor cornea engraftment, the levels of MMP-9 and TIMP-1 in the tear must be high enough before the surgery and the concentration of the ferment should decrease timely after its main functions have been completed. A 2-fold (or greater) decrease of MMP-9 concentration in the tear on the 7th day after keratoplasty can be considered a marker of the favorable prognosis for engraftment.

The review is focused on the adherence of glaucoma patients to the immediate start of treatment after the condition has been diagnosed. A personalized strategy, which includes the assessment of the patient's clinical and socio-economic status and the use of medications with proven efficacy, contributes to the formation of long-term adherence to therapy. In particular, the strategy combines preventive and diagnostic measures depending on the patient’s individual characteristics and involves their direct participation. Over 250 risk factors are known to reduce a patient’s adherence to treatment, whereas insufficient adherence can itself be considered as a risk factor for glaucoma progression. The asymptomatic course of the disease or the lack of a noticeable effect of drops instilled often cause the regimen to be violated, whilst the long-term therapy requires determination and self-control of the patient. Combined measures to improve the adherence are based on the specific needs of the patients and are consistent with their lifestyle. As a rule, the patients need special instruction, good means of communication with the doctor, simplified treatment regimens, and an adequate interaction with the public health facilities. Importantly, the therapy start depends not only on the level of intraocular pressure, but also on the stage of the glaucomatous process at which it was first diagnosed.

Purpose. Studying clinical and cytological signs of malignant epithelial genesis tumors of eye adnexa. Material and methods. In 2015–2020, 308 patients aged from 23 to 87 (58.0 ± 6.7) years with suspected malignant neoplasms of eyelid skin and conjunctiva were cytologically examined. The material for cytological examination was obtained by scraping (n = 271; 88 %), imprinting (n = 27; 8.8 %), and fine needle aspiration biopsy (n = 10; 3.2 %) if the neoplasm was more than 10 mm thick. Preparations were processed and fixed according to the standard technique using panchromic Pappenheim staining. Results. The cytological analysis confirmed the clinical diagnosis and the epithelial genesis of the malignant neoplasm in 273 (88.7 %) patients. The benign nature of the tumor was confirmed in 17 patients (5.5 %) and the non-tumor nature of the process was confirmed in 11 patients (3.6 %). In the group of malignant tumors, basal cell cancer prevailed, affecting 240 patients (87.9 % of all malignant tumors). 27 patients (9.9% ) had squamous cell cancer, 4 patients had meibomian gland cancer in 4 patients, and 2 patients had undifferentiated cancer. Benign tumors included papillomas (n = 11), while tumor-like lesions included atheromas (n = 3) and granulation polyps (n = 3). Non-tumor lesions involved productive inflammation of the chalazion type (n = 7), or chronic inflammation of a reactive nature (n = 4). 22 patients had histological examination to check the diagnosis, in all cases the histological outcome coincided with the cytological diagnosis. Conclusion. The comprehensive clinical and cytological study allowed us to specify cytomorphological characteristics of epithelial tumors of the eye adnexa: the basal cell cancer and its varieties according to the clinical forms of the tumor, squamous cell cancer and meibomian gland cancer, and papilloma. The complex clinical and cytological method of diagnostics is easily applicable in out-patient conditions, allowing us to specify the diagnosis during the initial visit, which considerably reduces the time required for full patient’s examination.

It is believed that in degenerative diseases of the retina, photostimulation by fractal dynamics signals activates neuroplasticity, thereby increasing the efficiency of visual rehabilitation. Previously, we showed a positive effect of fractal phototherapy (FF) on the electroretinogram (ERG) of healthy rabbits and demonstrated the safety of long-term photostimulation courses for the retina. The purpose of this work is to study the effect of FF on the functional activity and morphology of the retina in rabbits with a model of retinal pathology. Material and methods. We modelled an atrophy of retinal pigment epithelium (RPE) on both eyes of 50 rabbits. 30 days after the administration of bevacizumab, the animals were divided into two groups of 25 animals each. In the main group, photostimulation was performed using a device for FF, while in the control group incandescent lamps were used that create radiation of constant intensity. In both groups, 20-minute binocular light stimulation sessions were performed daily, five times a week. ERG and optical coherence tomography of the retina were performed before and after courses of treatment which lasted 1 week, 1 and 3 months. Results. Long-term courses of FF were shown to be safe for the morphology of the retina of animals with the RPE atrophy model. In all periods of observation, biochemical studies revealed no statistically significant changes in the content of norepinephrine and dopamine in the tear as compared with baseline values. In the main group, a slight positive effect of FF on rod and cone ERG was found after 5 FF sessions, while a significant increase in the amplitude of the transient and steady-state pattern-ERG (PERG), most pronounced after a 1-month FF course, was observed. Conclusions. A positive effect of FF on the functional activity of retinal ganglion cells (RGC) may suggest that prescribing a course of FF lasting up to 1 month (20 sessions) in diseases accompanied by a pathology of RGC is advisable, whereas for patients with a pathology of the macular region, such as AMD, an effective improvement in the activity of photoreceptors and bipolar cells could probably be achieved through a 1-week course of FF, conducted under the control of electroretinography.

Purpose: to assess the reaction of multipolar retinal neurons to light irradiation depending on the intensity and duration of exposure. Material and methods. Outbred sexually mature white rats (n = 50, 100 eyes) weighing 180–200 g were exposed to continuous round-the-clock light (200, 3,500 lux; 1, 2, 7, 14, 30 days). The control group consisted of 25 non-irradiated animals (50 eyes). Using semifine sections, colored with toluidine blue, we counted the number of neurons in the ganglionic layer with karyopyknosis, focal and total chromatolysis. In the optic nerve, the percentage of degeneratively altered axons and the number of nerve fibers with deformation of the myelin sheath were calculated. Ultrastructural changes in neurons were studied using a JEM-100 CX-II electron microscope. Results. In the first days of the experiment (1, 2 days), reactive and destructive changes in organelles are observed in the perikaryons of multipolar retinal neurons. The granular endoplasmic reticulum becomes fragmented, loses part of its ribosomes, and vacuoles of varied sizes are formed from its cisterns. With an increase in the duration of exposure (7–30 days), degradation processes are increasing, all the more so after high-intensity (3,500 lux) light irradiation. The photodamage causes changes in all components of the optic nerve and is characterized by a destruction of organelles, a decrease in the number of elements of the cytoskeleton in the axon, and myelin sheath splitting. Conclusion. Changes in multipolar neurons of the retina after photodamage are primarily related to the content and distribution of the chromatophilic substance and depend on the intensity and duration of illumination.

The article presents a clinical example of intraocular presbyopia correction in a patient who previously underwent laser vision correction by LASIK for mild myopia. Before the surgery, the distance VA mono- and binocular was 1.0, ADD for reading distance 40 cm +2.0 D, objective refraction sph +0.5 D cyl -0.25 D ax 980, left eye sph +0.75 D cyl -0.25 D ax 660. The patient was given a simultaneous bilateral refractive lens exchange with an implantation of a trifocal aspheric intraocular lens in the right eye and a trifocal toric aspheric intraocular lens in the left eye. We used the following IOL calculation formulas: ASCRS mean IOL power, Shammas formula, Barrett true K formula, Masket formula, Modified Masket formula, Haigis-L formula. 1 week postop: UDVA OU = 1.0, UNVA 40 cm = 1.0, UVA 70 cm = 0.7. The objective refraction OD was sph +0.0, D cyl -0.75 D ax 163, OS sph +0.25 D, cyl -0.0 D. The compliance with the modified algorithms of pre-and intraoperative behavior of the operating team, thorough preparation of the patient, careful calculation of the IOL allowed us to obtain the predictive refractive result with a high level of visual satisfaction and absence of undesirable postoperative phenomena. The patient underwent the examination with Salzburg reading desk before and after the surgery, to confirm the excellent functional results of the treatment. Despite the fact that simultaneous same day IOL implantation in both eyes, especially in eyes with previously operated corneas, is still disputable, the above case confirms that with modern equipment, precise multi formula calculation, and ample experience help achieve excellent functional and refractive results.
文章介绍了一个眼内老花矫正的临床案例，患者曾因轻度近视接受过 LASIK 激光视力矫正手术。手术前，单眼和双眼 VA 距离为 1.0，阅读距离 ADD 为 40 cm +2.0 D，客观屈光度 sph +0.5 D cyl -0.25 D ax 980，左眼 sph +0.75 D cyl -0.25 D ax 660。 患者同时接受了双侧屈光晶体置换术，右眼植入一枚三焦点非球面眼内晶体，左眼植入一枚三焦点散光非球面眼内晶体。我们使用了以下人工晶体计算公式：ASCRS 平均 IOL 功率、Shammas 公式、Barrett 真 K 公式、Masket 公式、修正 Masket 公式、Haigis-L 公式。术后 1 周：UDVA OU = 1.0，UNVA 40 cm = 1.0，UVA 70 cm = 0.7。客观屈光度 OD 为 sph +0.0，D cyl -0.75 D ax 163，OS 为 sph +0.25D，cyl -0.0 D。手术团队术前和术中行为遵守修改后的算法，患者准备充分，人工晶体计算仔细，使我们获得了预测的屈光结果，视觉满意度高，术后无不良现象。患者在手术前后接受了萨尔茨堡阅读台检查，以确认治疗的良好功能效果。尽管双眼当天同时植入人工晶体，尤其是在角膜曾接受过手术的双眼中植入人工晶体仍存在争议，但上述病例证实，现代化的设备、精确的多公式计算以及丰富的经验有助于获得极佳的功能和屈光效果。

The article presents a variety of ways to increase the efficiency of glaucoma filtering surgery. Special attention is given to maintaining the ocular surface healthy through optimal glaucoma therapy. The duration of the disease should be taken into account when choosing the type of hypotensive surgery and designing an algorithm for its pharmacological support: preoperative preparation, prolonged postoperative anti-inflammatory treatment and cornea protection.

Diabetes mellitus (DM) is a major public health problem, with approximately one third having signs of diabetic retinopathy (DR). In such patients, cataracts develop at an earlier age and 2–5 times more frequently. The incidence of macular edema (ME) after phacoemulsification of cataracts (FEC) in patients with diabetes has been shown to increase by 1.80 times and, in the presence of DR by 6.23. The critical period for retinal deterioration is 2 months after FEC, which requires an active therapy and monitoring. For patients with pre-existing diabetic macular edema (DME), If the cataract does not affect daily activities of patients with a pre-existing DME and the optical clarity is adequate, it is preferable to postpone surgical treatment in order to maximize retinal stabilization on OCT at two consecutive visits with a month’s interval between. In the case of severe impairment of lens transparency, FEC with an intravitreal injection of anti-VEGF 28 days or steroids 1 month before surgery under strict monitoring of the retinal condition using OCT is recommended. If macular changes are absent and there is a risk of developing DME, the use of nonsteroid anti-inflammatory drugs is necessary. Prophylactic intravitreal therapy is unacceptable in the absence of MO.
糖尿病（DM）是一个重大的公共卫生问题，约三分之一的糖尿病患者有糖尿病视网膜病变（DR）的迹象。在这类患者中，白内障的发病年龄较早，发病率是正常人的 2-5 倍。研究表明，糖尿病患者在白内障超声乳化术（FEC）后黄斑水肿（ME）的发生率增加了 1.80 倍，而在出现 DR 的情况下则增加了 6.23 倍。白内障超声乳化术后 2 个月是视网膜恶化的关键时期，需要积极治疗和监测。对于已有糖尿病性黄斑水肿（DME）的患者，如果白内障不影响已有 DME 患者的日常活动，且光学清晰度足够，最好推迟手术治疗，以便在连续两次就诊时（两次就诊之间间隔一个月）通过 OCT 最大限度地稳定视网膜。如果晶状体透明度严重受损，建议在手术前 28 天进行抗血管内皮生长因子（anti-VEGF）玻璃体内注射，或在手术前 1 个月注射类固醇，同时使用 OCT 严格监测视网膜状况。如果没有黄斑病变，但有发展成 DME 的风险，则有必要使用非类固醇抗炎药物。如果没有黄斑病变，则不能接受预防性玻璃体内治疗。

The microflora of the ocular surface serves an important role in the protective mechanisms, since it significantly affects the regulation of immunological activity and the barrier effect against pathogen invasion. The presence of a healthy ocular microbiome causes no eye diseases, and ophthalmic pathologies develop only when anatomical barrier functions and immune status are violated. A healthy eye surface is characterized by a relatively stable and small microbiome diversity. The environment, diet, gender, age and some other factors, such as potential contamination, affect the composition of the microbial flora, complicate its analysis and may affect the results of the latter. Moreover, potentially pathogenic organisms various disorders, including inflammation and methods of treating ocular surface can also affect the composition of eye microbioma. Traditional microbiological studies based on cultivation often reveal a rather low diversity of microorganisms in a particular region. New research methods, e.g. genetic analysis based on rRNA sequencing, indicate a much greater diversity than previously assumed. It has been shown that changes in the microbiota composition occur in blepharitis, conjunctivitis, keratitis, uveitis, dry eye syndrome, age-related macular degeneration, diabetic retinopathy, glaucoma, myopia, etc.Currently, there are no clear criteria for describing norms of the ocular microbiome (including fluctuations which should be considered normal during life). The features and impact of the microflora composition on immunity and human body as a whole, in particular, those associated with the intestinal microbiome and their dependence on gender, age, place of residence, etc have not been studied in full.Further studies of eye microbiome can give answers to all these questions.
