Hypermetropia as a Risk Factor for Age-Related Macular Degeneration. Review
Authors: Likhvantseva V. G. , Kapkova S. G. , Gevorgyan A. S. , Nekrasova E. Yu.
Published: July 2022

The authors presented a complete comprehensive analysis of the combined data of 11 cross-sectional (static) and 11 longitudinal cohort studies with follow-up durations of 5 to 14 years, 16 case-control studies, as well as 3 systemic meta-analyses and 1 “umbrella” study evaluating the scientific hypothesis that hypermetropia is a risk factor for the development of age-related macular degeneration (AMD). In these studies, AMD was verified against the diagnostic criteria of three different classification systems: those of the National Eye Institute (USA), the International System for the Study of Age-Related Maculopathy, and the Wisconsin Classification WARMGS. A total of 82308 patients with AMD were enrolled. 3 baseline indicators in the population were analyzed: the initial hypermetropia, the spherical coefficient (SE) and the axial length of the eye (AL), on the one hand, and the prevalence of AMD, on the other hand. Traditional statistical indicators were calculated: the risk ratio (RR) of AMD among hypermetropes compared to emetropes and a 95 % confidence interval (CI). Pooled data from meta-analyses showed significant associations between farsightedness, SE, AL, and the prevalence of early AMD. The combined RR and 95 % CI were: 1.13 (1.06–1.20), 1.10 (1.07–1.14), and 0.79 (0.73–0.85), respectively. An increase in SE by diopter was correlated with early AMD (RR 1.06; 95 % CI 1.02–1.10). The late AMD did not confirm its association with the refractive error. The umbrella meta-analysis lowered the statistical significance of this association for early AMD (RR 1.08, 95 % CI 1.01–1.18); with late AMD (RR 0.84, 95 % CI 0.77–0.91). In general, experts came to the conclusion that the likelihood of developing AMD depends on the refractive status of the patient.

Relevance. Today, keratorefractive surgery is a high-tech branch of ophthalmology and provides a predictable, high-precision, stable and safe refractive result in patients with a wide range of refractive disorders.

Purpose. To evaluate the clinical and functional results of myopia correction using the technology of fractional lenticular extraction performed using femtosecond VisuMax and LDV Z8 lasers.

Materials and methods. Within the framework of this work, 160 patients (160 eyes) with inpatient myopia of medium and high degree were examined and operated, with average keratometry parameters (43.0–45.0 dptr), aged from 18 to 36 years. The follow-up period was 1 month after the operation. The SMILE group was formed: a group of patients who underwent surgery using refractive lenticular extraction technology using a femtosecond VisuMax 500 laser (80 eyes); and the CLEAR group: a group of patients who underwent surgery using refractive lenticular extraction technology using femtosecond laser Femto LDV Z8 (80 eyes).

Results and discussion. Operations with SMILE and CLEAR technology were performed in the Department of refractive laser surgery of the FSAU NMIC MNTC “Eye Microsurgery” named after S.N. Fedorov of the Ministry of Health of Russia (Moscow) according to standard protocols. No intraoperative complications were recorded. The analysis of comparable clinical and functional results of myopia correction using the technology of fractional lenticular extraction performed using femtosecond VisuMax and LDV Z8 lasers was carried out.

Conclusion. Thus, the analysis of the clinical and functional results of correction of myopia of medium and high degree by the technology of refractive extraction of the lenticle performed using femtosecond lasers VisuMax and LDV Z8 showed their high comparability in terms of efficiency, safety, predictability and stability. A new technology of fractional lenticular extraction using a comprehensive assessment of the condition of the ocular surface at the preoperative stage, which allows to identify and eliminate the changes that have occurred, can be recommended for widespread clinical implementation.

Objective: to analyze the results of treatment in patients with refractory glaucoma of various stages of the disease by microimpulse cyclophotocoagulation.

Patients and methods. We examined 43 patients aged 68.5 ± 13.2 years with primary open-angle repeatedly operated subcompensated glaucoma (POAG) of advanced (13) and advanced (30) stages before and after performing MCPC (SUPRA 810 device, QuantelMedical, France) using standard laser parameters: energy W = 2000 MJ, 31.3 % — duty cycle, exposure time — 80 seconds per hemisphere.

Results. The operation and postoperative period were uneventful. The hypotensive effect was achieved in all cases up to 6 months of follow-up. In the advanced stage of the disease, IOP decreased from 26.8 ± 7.8 mm Hg to an average of 17.1 ± 8.1 mm Hg (p < 0.05), and the amount of antihypertensive agents decreased from 2.89 ± 0.74 to 2.4 ± 0.6. in patients with advanced stage, IOP decreased from 29.9 ± 7.8 mm Hg to 21.0 ± 8.3 mm Hg (p < 0.05), and the amount of antihypertensive agents decreased from 3.1 ± 0.4 to 2.8 ± 0.5. The maximum corrected visual acuity (MCI) in all patients remained at the preoperative level during the entire follow-up period.

Conclusion. Analysis of the results has shown that the use of microcyclophotocoagulation in patients with refractory glaucoma has not led to the development of postoperative complications, reduced intraocular pressure by 36.2 % from baseline, when developed and 29.8 % in advanced stages of the disease, reduced the number of antihypertensive drugs was 17 % in the second and 10 % at third stage and have not led to a decrease in visual function at 6 months follow-up. Thus, it is proved that the use of a diode laser in micro-pulse mode during microcyclophotocoagulation is a safe and effective method of treating refractory forms of glaucoma at various stages of the disease.

Published: July 2022

Relevance. Modern keratorefractive surgery is a high-tech field of ophthalmology aimed at solving various problems of correcting a wide range of ametropias.

Objective: to formulate recommendations for refractive surgeons when planning the correction of hypermetropic refraction using modern keratorefractive surgery.

Materials and methods. An analysis of 20 literature sources and a retrospective analysis of outpatient records of 188 patients with hypermetropia who underwent surgery were carried out.

Results. The analysis of the literature and our own clinical study allows us to recommend focusing on the final keratometry after keratorefractive surgery, which should not exceed 48 diopters. Among the analyzed charts of patients in compliance with these criteria, the accuracy of hitting the target refraction in the range of ± 1 D was 98.9 %, the regression did not exceed 0.5 D from that obtained 1 month after surgery in 96.8 %, and the loss of 1 line of BCVA was 3.7 % of cases. Among patients with achieved keratometry above 48 diopters, the loss of line 1 BCVA was 13.8 %, line 2 — 2.7 %.

Conclusion. Thus, the tactics of correction of hypermetropia by CRC methods require an integrated approach to the assessment of visual functions, drug preparation for surgery, careful implementation of the surgical stages of the intervention, and rational postoperative pharmacological support.

Purpose: to develop a comprehensive method of meibomian gland dysfunction (MGD) treatment, including the periorbital zone massage, aimed to improving the microcirculation of the eyelids and the functional activity of the meibomian glands, evaluating its effectiveness and safety.

Patients and methods. The study included 92 patients (184 eyes) with all forms of permanent residence in accordance with the international classification of the DEWS working group, 32 of them were men and 60 women. All patients included in the study at the first stage of work were randomly divided into 3 groups, depending on the type of therapy. The first group included 34 patients (68 eye), in which complex therapy was carried out in the form of eyelid hygiene + massage in the periorbital zone according to the methodology developed during the study, the second group included 30 patients (60 eyes) who underwent IPL therapy (the use of intense pulsed light in the periorbital zone), the third group included 28 patients (56 eyes) who were treated in the form of eyelid hygiene (warm compresses + eyelid self-massage).

Results and discussion. A technique of massage in the periorbital zone was developed, its effect on hemodynamic parameters of the eyelids was studied, and to assess its effectiveness, a comparison of hemodynamic parameters of the eyelids was carried out with two other methods of thermal exposure — eyelid hygiene (warm compresses + eyelid self-massage) and IPL therapy. It was found that all three types of exposure — IPL therapy, eyelid hygiene and eyelid hygiene + massage in the periorbital zone, carried out according to the original technique, lead to an increase in hemodynamic parameters of the eyelids and in the lacrimal artery (according to laser Doppler flowmetry and color Doppler mapping) to varying degrees of severity, which should contribute to an increase in the metabolism of Meibomian glands, therefore, and the improvement of their functional activity. At the same time, 3 months after the treatment starting, the improvement of the the meibomian glands’ functional activity of was higher in the group of patients in which IPL therapy and complex effects — eyelid hygiene + massage in the periorbital zone were performed, compared with the group with only eyelid hygiene. However, after 6 months, high indicators of the functional activity of the meibomian glands remained only in the group with complex effects — eyelid hygiene + massage in the periorbital zone. Such a therapeutic effect, according to the results of the study, improves the patients’ quality of life according to data of the SPEED questionnaire and directly depends on adherence to treatment on the Morisky scale (MMAS).

Conclusions. The presented complex of therapy can be recommended for wide application in ophthalmological practice for the treatment of dysfunction of the meibomian glands.

Published: July 2022

Purpose: to study the hemodynamic parameters in the eye’s vessels in children with endogenous uveitis, depending on the localization and degree and activity of the inflammatory process.

Patients and methods: 67 children aged 6 to 18 years were examined. Of these, 19 people (35 eyes) were diagnosed with anterior uveitis, 20 (38) — peripheral, 8 (14) — posterior, 10 (20) — panuveitis. There were subgroups according to the degree of inflammation activity in each group. There were 10 healthy children (20 eyes) in the control group. The maximum systolic (Vsyst), final diastolic (Vdiast) blood flow rate and resistance index (RI) in the ocular artery (GA), central retinal artery (CAC), posterior short ciliary arteries (ZCCA), central retinal vein (CVS) and superior ocular vein (VGV) were detected with the method of the Color Duplex Scanning (CDR).

Results. The maximum systolic and final diastolic blood flow rates in GA decrease, and in panuveitis, on the contrary, increase in anterior uveitis on the location of active inflamation. In panuveitis, the blood flow rate in the HBV also increases. In peripheral uveitis, there is a decrease in systolic and diastolic blood flow rates and an increase in the resistance index in CAC and WCC. With posterior uveitis, the blood flow in the HBV slows down and the RI in the CAC and WCC increases.

Conclusion. In children with active uveitis, according to the CDR, hemodynamic changes in the vessels of the eye are observed, it depends on the localization of the inflammatory process. They have multidirectional nature. In most cases, a decrease in blood flow rate and an increase in RI are detected. The study of the eye’s hemodynamics can be an additional criterion for assessing the activity of inflammation and the effectiveness of therapy, as well as differential diagnosis of various localization of the uveitis.

Published: July 2022

This article is a continuation of a series of publications on the results of an experimental study on the possibilities of using quantum dots, as well as bioconjugates based on them as a promising treatment for inflammatory diseases of the eye. Of the whole variety of microorganisms, Pseudomonas aeruginosa (Pa) is the most formidable pathogen, leading to pronounced, sometimes fatal, changes throughout the body in general, and in the eye in particular, in connection with which it receives close attention from bacteriologists and specialists dealing with the treatment of pathologies caused by this microorganism. Now, the search for effective methods to combat this pathogen is one of the priorities of world health care.

This article presents an analysis of the anti-infectious activity of bioconjugates based on quantum dots KTCdTe / CdMPA710 and KTInP / ZnSe / ZnS650 in synergy with III generation cephalosporin (Cefotaxin) against nosocomial Pa strains. Cultures of microorganisms, in the amount of 30 Petri dishes, were incubated in a thermostat at 350C for 18 hours (in the dark and under a source of photoexcitation). As a source of photoexcitation (the emission spectrum of the source corresponded to the absorption spectrum of QDs), we used an LED strip connected to an uninterruptible power supply battery placed in a thermostat. Evaluation of the effectiveness of the impact was carried out using the disk-diffusion method with the measurement of effective growth retardation zones (GRZ). According to the results of the study, it was revealed that the use of the obtained bioconjugate (QD + AB) significantly increases the ZZR.
Modified Immediate Sequential Bilateral Cataract Surgery (Clinical Cases)
Authors: Medvedev I. B. , Pokrovsky D. F.
Published: July 2022

Purpose. Analysis of two clinical cases of immediate sequential bilateral cataract surgery according to the developed modified algorithm (mаISBCS).

Materials and methods. The results of two clinical cases of mаISBCS are presented. In both cases, ultrasonic cataract phacoemulsification (FEC) was performed with implantation of an intraocular lens (IOL) under local anesthesia according to the standard technique through a corneal incision of 2.2–2.4 mm. IOL calculation was performed for emmetropic refraction. The modification (compared to the traditional one) of the technology of surgical intervention was based on the inclusion in the algorithm of a long (at least 60 minutes) break between operations for the purpose of a comprehensive ophthalmological examination with a further decision to perform an operation on the second eye.

Results. In the first clinical case, the patient failed to measure the anterior-posterior axis by optical biometry before surgery. In such situations, the A-scan is used, which is considered less accurate due to human error and often leads to errors in the calculation of the IOL. In addition, a certain alertness was introduced by the fact of a significant (4 diopters) difference in the preoperative refraction of both eyes. Considering these provisions, after the first operation, after 60 minutes, the correctness of the IOL calculation was monitored by two methods — by measuring (optical biometrics) the anterior-posterior axis of the eye (APA, while the differences were less than 0.3 mm, which confirmed the A-scan data), as well as autorefractometry, which showed almost no deviation from the “target”. The presented results allowed us to formulate a decision to carry out the second operation. In the second clinical case, despite the absence of risk factors (optical biometrics was taken in two eyes, similar APA values), a postoperative refraction of +1.5 diopters was determined in the operated eye, which, apparently, is associated with the identified decrease (by 0.93 diopters) corneal curvature due to hydration of the corneal stroma in the area of surgical accesses and (or) changes in the tear film. The presented results allowed us to formulate a decision to postpone the second operation. At the same time, after a week, the restoration of the corneal tissue was noted, which was proved by the required (0.37 diopters) deviation of refraction from the target values.

Conclusion. The use of mаISBCS technology provides the required clinical efficacy and can be recommended taking into account the epidemiological situation, especially for people with visually strenuous work.

The World Health Organization announced a new coronavirus pandemic on 11 March 2020. It is known that the most frequent clinical manifestation of a new coronavirus infection is lung damage with the evolution of pneumonia, as well as respiratory distress syndrome. The highest risk of severe traction and death is known to occur in the immunosuppressive group of patients. These patients include rheumatologically patients. Currently, there is no complete understanding of the pathogenesis of the development of covid-19, as well as the pathogenesis of the development of autoimmune diseases. In a pandemic, the question of how the coronavirus infection proceeds in patients on immunosuppressive therapy, in particular on anti-B cell, is relevant. In our case report presents a 69-year-old female with ANCA-associated vasculitis remission having received a B-cell-depleting therapy with rituximab (RTX), who had an ocular lesion as a clinical manifestation of Coronavirus disease 2019 (COVID-19). Two months after RTX treatment, COVID-19 was diagnosed. The patient had extrapulmonary manifestations including central nervous system involvement and ocular symptoms such as conjunctivitis, without respiratory pathology. In this clinical observation, the patient’s disease manifested itself with right-sided conjunctivitis, which is a rare manifestation as the first symptom. This article describes the features of the course and outcome of the disease, as well as, the protective effect of RTX in course of COVID-19 is discussed. A comparative analysis of cases of COVID-19 with eye damage is being carried out. This clinical observation is of great value for doctors of all specialties, especially ophthalmologists. A multidisciplinary approach is crucial to manage COVID-19.

Cacopsylla pyri L. (Hemiptera: Psyllidae) is one of the most serious economic pear pests in Eastern Croatia. Previous methods of pear control in the Republic of Croatia have led to the development of an insect population resistan to certain active ingredients. The objectives of this two-year study were to determine the optimal number of treatments for psylla control based on the monitoring of pest life cycle and to determine the effectiveness of processed kaolin in controlling the pear psylla in comparison with other chemical insecticides in four different treatments (T1. IPM-integrated protection program – diflubenzuron, spirotetramat, abamectin, acetamprid; T2. acrinatrin + abamectin, T3. kaolin clay, T4. control treatment). The research was conducted in 2017 and 2018 in a six-year-old experimental pear orchard on three varieties (Williams, Conference, and Abate Fetel). Monitoring of the pest population and its development was performed by visual inspection on two one-year shoots per tree of each variety in all replicates. The T1 treatment demonstrated the highest efficiency, between 84-95%, depending on the year, while the kaolin treatment had the lowest one, but it varied greatly from one year to the other (37-71%).

Authors: Hoang Thi Hien Le
Published: July 2022

Climate change and its impacts on culture, society, and history in the Southern region is a topic with many topical and humanistic meanings in Southern literature, especially in the early years of the 21st century. One of the prominent Southern writers who soon showed their consciousness in the green revolution was Nguyen Ngoc Tu. Through collections of short stories such as Cánh đồng bất tận, Khói trời lộng lẫy, Nguyen Ngoc Tu has provided indicators of nature with concerns, confrontations, and challenges. We study those indicators to sketch a multi-dimensional picture in the art world of Nguyen Ngoc Tu, and at the same time pose urgent problems that exist in the Southern river region. From an ecological point of view, we want to point out the "forecast" and "warning" role of modern literature on the dangers and current state of the environment, and at the same time require the active participation of the modern literature. scholars and writers to solve problems of contemporary life.

The study aimed to analyze the equality in the marriage relationship of Buddhism through the Nikaya Canon. Analytical and comparative methods were mainly used in the study. Research results showed that, even though it has been more than 2600 years, the Buddha’s teaching on marriage has never been out of date. To have a happy marriage, the husband and wife have to achieve four similarities or homogeneity, including, Samasaddhā, Samasīla, Samacāgā và Samapaññā. The application of Buddha’s teachings to life in general and marriage, in particular, has a profound meaning and brings many values to human development. From the analysis results of the typical ideal family model when the Buddha was alive as “Nakula’s parents” – the marriage is built on the spirit of Buddha’s thought along with Buddhist views on equality. The research proposed a method of practice to maintain a stable marriage foundation in the spirit of the Buddha’s teachings, contributing to building a healthy spiritual life for modern Vietnamese people.

As the global economy grows, the labor market's demand for qualified employees increases. However, the present situation is not able to meet labor market requirements; laborers are inexperienced, and their professional skills are inadequate. Collaboration between vocational schools and businesses is essential for educational activities. This study aimed to investigate the degree of perception, the contents, the forms, and the variables that influenced collaboration activities in practical training between vocational schools and businesses. A quantitative study method was conducted on 570 respondents (195 teachers, 125 managers, and 250 graduated students) randomly recruited from four provinces/cities in Vietnam. The results show that participants perceived the importance of practical teaching coordination activities in vocational schools and businesses. In addition, some contents and forms were applied to collaboration teaching activities between vocational schools and businesses Future studies should consider similar experimental studies to develop appropriate practical training collaboration activities models based on perception levels and factors impacting activities.

The purpose of the research was to experimentally study the influence of a porous polyurethane partition on the flow parameters and on the flame front propagation in front of the partition upon initiation at the open end of the channel. The flame front velocities were determined in a hydrogen-air mixture at atmospheric pressure in a channel open on both sides with an inner diameter of 20 mm. The ratio between hydrogen and air was varied, so that the molar excess of hydrogen varied from 0.3 (ultra-poor mixture) to 1.0 (stoichiometric composition). The pore size varied within 0.3--2.5 mm, which corresponded to the number of pores per inch in the range of 10--80. The coefficients of hydraulic resistance of a polyurethane partition with an open pore type, depending on the size of the pores and the thickness of the partition, were calculated from the pressure loss when the air flow passes through the porous element. The flame front velocity was determined using the shadow method and high-speed survey. Findings of the research show that the optimal value of the thickness of the porous partition, after which the polyurethane partition begins to show filtration properties, in most cases is approximately equal to twice the pore size and the drag coefficient depends linearly on the total thickness of the partition. In this case, the deficit of the flow velocity with increasing thickness increases according to a power law. A qualitative correspondence between the flame front velocity in front of the porous partition and the flow velocity deficit is shown

Authors: Kanagasabai L.
Published: July 2022

In this paper Enhanced Synthetic Biome Optimization (ESBO) and Green Algae algorithm (GAA) is designed to abridge the power loss. Synthetic Biome Optimization (SBO) algorithm is a nature-inspired optimization algorithm, stimulated by the stream of energy in a biome on the world. The biome can be enunciated as a cluster of existing entities living in a certain province and the biome outlines the associations among them. The deprived entity (creator) is rationalized by the upper and low borders of exploration space and the pre-eminent entity (putrefaction). Levy flight applied to augment the exploration and imitate the food probing process of many faunae. In order to augment the convergence characteristics of the SBO algorithm, sine-cosine functions has been incorporated in the technique. This augmentation will stimulate divergent solutions and modifies in the direction of the distinguished prospective solution in ESBO. Proposed GAA approach imitates growing, reproduction deeds of green algae in sunlight. Green algae live in the shape of algal colonies which consist of algal cells. When green algae in least amount of sunlight it will be small size, energy and particularly starvation level will be high, but it will attempt to acclimatize by using adaptation probability in the ambiance where it positioned. Enhanced Synthetic Biome Optimization and GAA appraised in IEEE 57 and 300 bus systems. Assessment with other techniques has been done. Projected ESBO and GAA approaches abridged the power loss meritoriously

Published: July 2022

The antioxidant properties of ethyl acetate extracts of fruits, leaves and bark of the Osage orange (Maclura pomifera) tree were studied by a kinetic method using the example of a model reaction of cymene oxidation. The extracts exhibit antioxidant properties. Findings of the research show that fresh orange maclura fruits contain the greatest amount of antioxidants. At a temperature of 348 K, the effective content of antioxidant substances is 1.05 · 10--3 mol/(l · mg). The analysis of the effective content of antioxidants in each extract revealed that it decreases when the extract is stored at room (289 K) temperature. Antioxidant activities of antioxidants were determined --- rate constants of InH + RO•2→ ROOH + In•. According to the content of antioxidants, the ethyl acetate extracts are distributed in the following order: fruits > bark > leaves, and according to antioxidant activity --- bark > fruits > leaves. The dependence of the effective content of antioxidants on the measurement temperature was examines. The study shows that the effective content of antioxidants increases, especially in the extracts of dried fruits, leaves and bark of Osage orange, with decreasing temperature. This is due to a decrease in the additional initiation of primary radicals as a result of the autoxidation of easily oxidizing substances contained in the extracts
