The purpose: to develop a technology for the surgical treatment of macular retinal tears using an “effective” fragment of the ILM with an optimal shape, size, and localization, and evaluate its anatomical and functional efficiency.Methods. There were 10 patients (8 women, 2 men) with primary through macular holes of large diameter (more than 400 microns) under observation. The age were from 55 to 64 years old. The duration of macular tear existence ranged from 4 to 11 months. Patients underwent standard research methods, SOCT and microperimetry. To retain the point of visual fixation and eliminate the risk of retinal trauma, all patients underwent surgical treatment of macular tear using the developed method for the surgical treatment of macular retinal tears using an “effective” ILM fragment of the required shape, size and localization. Before the operation, individual parameters for each patient and zones of localization of the “effective” ILM fragment were calculated, which consisted of two parts: the upper inverted fragment and the intact foveolar fragment of the inner limiting membrane. The follow-up period was 1, 3, 6 months and 1 year after the operation.Results. Surgical treatment of MR in all patients was carried out completely without complications. In all cases, it was possible to preserve the zone of the foveolar intact fragment of the ILM and form the upper inverted fragment of the ILM, which directly covers the macular hole. Improvement of the anatomical state of the retina in the foveal area was achieved according to SOCT data. After 1 month, all patients had a “defect” (hyporeflective area) in the ellipsoid zone of photoreceptors with a width of 112 to 357 μm. The outer boundary membrane was clearly visible and had a linear profile. A complete resorption of edema along the edges of the tear happened. An intact foveolar fragment of the ILM was visualized on the surface of the retina, blocking the macular hole. After 3 months, in 3 patients, the defect of the outer layers of the retina completely disappeared. After 3, 6 and 12 months, the state of the retina of these patients was unchanged. All patients showed improvement in functional outcomes after surgical treatment. There was an increase in BCVA at all terms.Conclusion. The developed technology of surgical treatment using an “effective” ILM fragment is modern and safe in the treatment of penetrating primary macular retinal tears, and reduces the risk of intra- and postoperative complications.

Relevance. Diabetic retinopathy occupies one of the leading places in the frame of blindness and low vision. The very first changes in the retina in diabetic retinopathy are disorders of microcirculation and blood supply in the small vessels of the macula. There are few effective drugs that can restore perfusion in the small retina’s vessels. In this connection, it is relevant to search for anticoagulants that allow restoring blood supply in the macular area in diabetic retinopathy in the early stages.The purpose. To analyze the research of a domestic direct-action anticoagulant from animals, a drug of the heparin group Pyavit, both in ophthalmology for diabetic retinopathy and in other fields of medicine. The analysis of publications on eLibrary and PubMed resources for the last 30 years was done, by the keywords: direct-acting anticoagulants, diabetic retinopathy, hirudins, hemodynamics, optical coherence tomography (OCT), hemostasis. The data on the study and application of the drug from its development to its use in diabetic retinopathy, retinal vascular pathology, and pregnancy was analyzed. Researchers have studied the importance of the salivary gland secretion of a medical leech, which is a regulator of the hemostasis system. In 1992 I.P. Baskova patented a new drug Pyavit, which is officially approved for use in medical practice (registration number No. 000363/02). Dosage regimen: 300 mg three times a day for 20 days, and repeat the course through 1–2 months. In ophthalmology, researchers have proven the positive effect of the drug on the retina in diabetic retinopathy with an improvement in visual acuity, retinal thickness according to objective indicators of optical coherence tomography, fluorescence angiography, and hemostasis system.Conclusion. The analysis of scientists’ research allows us to expand knowledge about the positive effect of the drug Piavit on the path of diabetic retinopathy. Based on this review, the authors plan to further study the drug, which will assess the importance and significance of improving microcirculation in the macular area of the retina using the anticoagulant Pyavit to preserve visual functions.

Purpose: to study the severity of dry eye symptoms in patients who wear contact lenses and in those who underwent laser keratomileusis a long period ago according to OSDI questionnaire.Methods. 88 patients with various refractive disorders were included in the study, there were 33 men and 55 women. Mean age was 30,11 y.o. All patients were divided into 3 groups according to method of refractive disorder correction. Groups were equal in age and gender. The first included 27 patients wearing soft contact lenses for more than 5 years. The second group contained 33 patients who didn’t use contact lenses. The third one included 32 patients who underwent refractive surgery (LASIK, Femto-LASIK) more than a year ago. Assessment of severity of dry eye symptoms was performed according to questionnaire data (patients’ subjective feelings), objective data was not taken into account. Survey was performed with the use of OSDI questionnaire.Results. According to the symptoms presented the incidence of dry eye syndrome was 73.91 % in patients of the first group and it was 56.25 % and 66.66 % in the second and third one, moreover, the prevalence of DES in each of the groups was higher among women and amounted to 94.11% in the first group; 63.63% — in the second and 61.11% — in the third group. Mean OSDI in the first group was 31.48 ± 22.17; and it was 18,83 ± 14,00 and 22,25 ± 15,53 in the second and third group respectively. The obtained data corresponded to moderate severity of dry eye syndrome in all groups. DES was more prevalent among women in each group.Conclusion. The prevalence of DES according to the severity of symptoms was 65.6 %, the severity of DES was predominantly moderate. There was definite connection of symptoms and such risk factors as female sex and contact lens wear. Despite the connection with underlying pathogenetic mechanisms, the spread and severity of dry eye symptoms in patients a year after refractive surgery were significantly lower compared to those who didn’t undergo any refractive surgical procedures.

Published: July 2023

Ophthalmological manifestations in COVID-19 infection are diverse, manifesting themselves in all anatomical structures of organ of vision, they occur both in the acute period of the disease and in the post-COVID period. Currently, the literature describes changes in the anterior segment of the eye more often, and also there are publications describing pathological changes in the posterior segment, and acute vascular pathology of the retina after COVID-19 infection in particular. It has been established that the comorbid background of the patient is of great importance in the development and the course of the disease. These findings are also confirmed by our two clinical observations of acute ocular vascular pathology after COVID-19. In the first case, retinovasculitis of the right eye complicated by thrombosis of the inferior temporal branch of the central retinal vein was described. The development of vascular pathology of the eye in this case was observed 1.5 months after the onset of the first symptoms of COVID-19 infection. The patient promptly turned to an ophthalmologist and was hospitalized to an eye hospital, where she received anti-inflammatory, hemostatic, anticoagulant, antibacterial, angioprotective, antioxidant therapy. As a result of treatment — the improvement of condition, restoration of visual functions. In the second presented case, we observed the development of an acute ischemic circulatory disorder of the retina of the left eye (thrombosis of the central retinal vein) 2.5 months after the onset of the disease with a new coronavirus infection. The treatment in an ophthalmological hospital included: steroid and non-steroidal anti-inflammatory drugs, antibiotics, mydriatics, haemostatics, angioprotectors, antioxidants, anticoagulants, vitamins. On discharge from the hospital, there was a slight improvement, but after 2 months, the condition of the left eye worsened again. The pathology of the organ of vision proceeded with the development of complication — secondary neovascular glaucoma of a refractory nature with an outcome to subatrophy of the eyeball. It was facilitated by the comorbid background of the patient: hypertension, type 2 diabetes mellitus, dyslipidemia.Based on the results of the analysis of clinical observations, the specific features of ophthalmological changes, their severity and dynamics on the background of comorbidity and the received therapy were established. The relationship between COVID-19 infection and complications of the organ of vision has been shown.

Nitrogen (N) is an essential nutrient widely used in maize crop production. The application of a high N rate is commonly practiced by growers as a "guarantee" of optimal growth and yield. However, excessive nitrogen consumption can cause wastage, negatively impact plants, and adversely affects the environment. This paper reports on the impact of N supply on leaf characteristics in maize. Maize was grown in an experimental plot of the Department of Agronomy, The Hungarian University of Agriculture and Life Sciences, Hungary, during the spring and summer of 2021 (May - October). Four observation plots consisting of ​​102 m area size were evaluated for various N levels (0, 50, 100, and 150 kg ha-1 N a.i) with marked plants sampling in four replications. Data collection on leaf traits viz. leaf number plant-1 (B), leaf number plant-1 (S), temperature 0C (leaf surface), SPAD, leaf length (cm), leaf width (cm), and leaf area (cm2) were measured one week after application in weekly sequences of N until the eighth week. The results showed that nitrogen fertilizer application increased the leaf number plant-1 (B), temperature, SPAD, and leaf width while contrasting with leaf number plant-1 (S). However, there was no difference in leaf length for all treatments studied. Although an increase occurred up to the use of 100 N. Whereas, the 150 N treatment showed low performance and exhibited a negative correlation for all traits except temperature and number of leaves (S). The results suggest that treatment of 100 N produced the best results in most traits studied. Furthermore, a detailed research study is needed to confirm the findings, as many other environmental factors influence maize plant growth.

Al-Quran is the holy book of Muslims that must be introduced from an early age. Introducing the holy Qur’an in the Early Childhood institution is over reciting, writing, and memorizing versicle. The approaches used by teachers however do not convenient to students’ characteristics. In addition, the teachers rarely integrate the themes of material to the verses of the holy Qur’an, such as: the environment, the universe, natural phenomena, water, air, and fire. The learning process will be better if the students understand the meaning in it. This can be completed by a scientific approach for their thinking skill. This study aims to identify the effectiveness of the scientific approach to interest of children aged 5-6 years in learning the Qur’an. This research is quantitative research with one group pretest-posttest design. The data were gained through observation, and were analyzed by using the T-test, namely paired sample test. The results proved that t count 5,436 ≥ t table 1,76 with significance value of 0,00 ≤ 0,05. It thus believes that Ha is accepted and Ho is rejected, which means the scientific approach is effective to students’ interest in learning the Qur'an.

Women are half of society and the male half, as the Prophet Muhammad has said. A society will be good if both men and women are good. In the current era, women really need inspiration from female role models. This study describes the inspirational female figures in the Qur'an who serve as role models for women. Using the interpretation perspective, this research takes 7 inspirational women whose stories have been immortalized in the Al-Qur'an. Seven female figures who are only mentioned in the Qur'an must be set as role models, including Imron's wife, Maryam bint Imran, Ibrahim's wife, Queen Balqis, Musa's mother, two Madyan women and Asiyah bint Muzahim. Based on the stories of these inspiring women, an inspiration or example is obtained, including: from Hanna's story we can learn that humans must be able to accept God's destiny sincerely, even though this destiny does not match expectations. Likewise with Maryam's story, from her, we can learn that women must be good at maintaining honor.
