Material and Methods: The ILM was peeled around the IMH in the conventional ILM peeling group. In the fovea-sparing ILM peeling group, an ILM flap was created temporally to the IMH (with an ILM remnant left attached to the margins of the IMH), folded over the hole and stabilized with viscoelastic. Gas tamponade with 20% SF6 or 15% С3F8 was used. In the postoperative period, IMH closure pattern was assessed. Thicknesses of the outer retinal layers, inner retinal layers and retinal nerve fiber layer in the macular region were measured at 1 and 3 months. Results: Totally, 70 patients (15 males and 55 females) had an IMH surgery in 71 eyes. The mean age (SD) was 65.7 (6.8) years. The median IMH duration (interquartile range (IQR)) was 3.0 (1.0-6.0) months, and the mean preoperative BCVA (standard deviation (SD)), 0.19 (0.16). Thirty-four eyes had an IMH surgery with conventional ILM peeling, and 37 eyes, an IMH surgery with fovea-sparing ILM peeling. The two groups were matched in terms of preoperative visual acuity and macular hole duration. IMH closure was achieved in 30/34 eyes (88.2%) in the conventional ILM peeling group and 33/37 eyes (89.2%) in the fovea-sparing ILM peeling group. Particularly, IMH closure was achieved in 13/17 eyes that received gas tamponade with 20% SF6 and 20/20 eyes that received that with 15% С3F8 in the latter group. The rate of correct IMH closure pattern was substantially higher (64% versus 47%) and median postoperative BCVA (IQR), significantly better (0.55 (0.35-0.7) versus 0.43 (0.35-0.6), р = 0.039) in the fovea-sparing ILM peeling group than in the conventional ILM peeling group. An analysis of variance found a significant effect of the type of IMH surgery and IMH closure pattern on the postoperative BCVA (F1 = 5.06, p = 0.027; F2 = 7.9, p = 0.0001). In both groups, we found a significant thinning of the total retinal thickness in the central 1-mm foveal zone at 3 months compared to 1 month after surgery. There was a significant thinning of the outer and inner retinal layers in the conventional ILM peeling group, and no significant thickness changes in the retinal layers in the fovea-sparing group. Conclusion: Our fovea-sparing ILM peeling technique is an effective treatment option for IMHs, and when used with gas tamponade with 15% С3F8, enabled a primary surgery IMH closure rate of 100%.","PeriodicalId":16674,"journal":{"name":"Journal of Ophthalmology","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135320522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of melphalan on the structures of the ocular anterior segment (including the cornea, iris and anterior lens capsule) is however, still unknown, since no relevant experimental studies have been carried out so far. Purpose: To experimentally assess the changes in the rabbit anterior segment induced by intracameral injection of various concentrations of the alkylating cytostatic melphalan. Material and Methods: Twelve adult Chinchilla rabbits (22 eyes; age, 5–6 months; weight, 2.5–3 kg) were involved in this experimental study and maintained in the vivarium of the Filatov institute in separate cages under standard conditions. Results: After a 5-µg melphalan injection, corneal and iris changes were reversible and the lens was still clear. With an increase in melphalan concentration in injection solution (to 10, 15 and 20 µg) and time point (to 1 month and 3 weeks) after injection, degenerative changes in some epithelial cells of the iris became irreversible, anterior capsular cataract developed, but the cornea and anterior chamber aqueous remained clear. After a single 20-µg intracameral injection of melphalan, there was depigmentation of the iris, posterior synechia and anterior capsular cataract. Conclusion: Clinical and ultrastructural responses of ocular anterior segment tissue to intracameral melphalan injection depended on the injected dose and time point after injection. Most cells of examined tissues showed the capability to restore their ultrastructure following ceasing of the toxic effect of the drug.","PeriodicalId":16674,"journal":{"name":"Journal of Ophthalmology","volume":"71 11-12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135272441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Valerii Semenovych was born on June 2, 1948, in Mykolaiv region, Ukraine. After completing his secondary school education, he went on to Odesa Medical School in 1964 which he graduated with Honors to become a medical assistant. After graduating with Honors in General Medicine at the Pirogov Odesa Medical Institute, he began his career as a junior researcher at the Functional Diagnostics Laboratory, the Filatov Institute of Eye Diseases and Tissue Therapy, in 1974. Valerii Semenovych was promoted to senior researcher and head of the Functional Diagnostics Department in 1987, and remained at the head of the department until his death. His first significant academic achievement was defending his Cand Sc (Med) thesis, Loss of Intraocular Pressure Control Secondary to Effects Exerted on Limbic System Structures, in 1981. He defended his doctoral (Dr Sc (Med)) dissertation, Early Functional Changes in the Visual System and the Pathological Mechanisms of These Changes in Autonomic Nervous System Dysfunction, in 1995, and was awarded the title of professor in 1998. Professor Ponomarchuk was academic secretary for the Dissertation Defense Council specializing in ophthalmology, from 1996 to 2006; expert of the State Dissertation Defense Board in clinical medicine, from 2006 to 2012; and expert of the State Commission for Academic Degrees and Titles at the Ministry of Education, Science, Youth and Sport of Ukraine in clinical medicine (surgical disorders), from 2012 to 2014. In 2002, he was elected a Vice-President of the Ukrainian Ophthalmological Society. His research and practical activities were focused on the physiology of vision, early functional diagnosis of disorders of the eye and visual system, and efficacy of treating various eye diseases with low-intensity physical stimuli (e.g., electric stimulation, photic stimulation and muscle stimulation). Professor Ponomarchuk also conducted studies on the effects of autonomic nervous system dysfunction on the eye, and the results of these studies laid down the foundation for a new area of ophthalmology, vegetoophthalmology. He developed various sets of techniques (electrophysiology techniques; studies of the central and peripheral fields of vision, cerebral and ocular circulation, and light sensitivity) for pre-clinical diagnosis of visual system disorders and comprehensive color vision evaluation. These techniques are successfully used at the Filatov institute and many eye centers of Ukraine. Professor Ponomarchuk was an active inventor. In 1988, he began his collaboration with engineers of “Shtorm” Research Institute to develop a number of diagnostic and treatment devices (ophthalmological electric and photic stimulators ","PeriodicalId":16674,"journal":{"name":"Journal of Ophthalmology","volume":"79 17-18","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135272889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In mature intumescent cataract phaco, the most difficult phase is performing a continuous capsulorhexis which should be as round as possible. The incidence of an anterior capsular tear during capsulorhexis has been reported to range from 0.8 to 5.0% and increases with an increase in cataract density. This is because in dense intumescent cataracts, capsulorhexis tends to extend to the periphery due to high intracapsular pressure. Femtosecond laser–assisted phaco of mature intumescent cataract enables a safe laser-assisted capsulotomy with a substantially reduced risk of intraoperative complications. Because this approach is as yet not widely used in ophthalmology, we aimed to share our experience in the use of femtosecond laser in phacoemulsification of mature and intumescent cataracts. Purpose: To assess the efficacy of femtosecond laser–assisted treatment of mature intumescent cataract. Methods: Sixty-five patients (68 eyes) with mature intumescent senile cataract underwent femtosecond laser-assisted cataract surgery (FLACS) with intraocular lens (IOL) implantation and were involved in this study. Results: In 55 eyes (80.8%), laser capsulotomy of the desired diameter (5.0 mm) was performed completely. In 8 eyes (11.7%), capsular bridges (capsular tissue remnants at the site of laser-assisted cut of the anterior capsule) were seen. In addition, after the laser phase of surgery, 3 eyes (4.4%) showed an irregularly shaped anterior capsular disc due to the failure of the laser to cut through the capsule in several regions. In all study eyes, the IOL was well centered in the bag. Conclusion: In eyes with mature intumescent cataract, it is reasonable to use the femtosecond laser for a safe and accurate anterior capsulorhexis to avoid the severe intraoperative complications (those associated with posterior capsular rapture and vitreous prolapse) that can be seen during manual capsulorhexis.","PeriodicalId":16674,"journal":{"name":"Journal of Ophthalmology","volume":"278 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135320876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Allergic rhinoconjunctivitis (ARC) is one of the most common clinical forms of AR. An imbalance between pro-inflammatory and anti-inflammatory cytokines is known to have a key role in allergic inflammation. Purpose: To compare cytokine and immunoglobulin levels among patients with AR and ARC treated with different therapeutic options. Material and Methods: Forty patients with AR and ARC (age range, 20 to 46 years) were included in the study. Disease duration ranged from 6 months to 2 years. Patients were divided into two subgroups of 20 patients each. Patients of subgroup 1 received the basic therapy (a 10-mg loratadin tablet daily and mometasone furoate nasal spray at a dosage of 200 μg once daily), whereas patients of subgroup 2, the basic therapy plus polypore macromycetes (Astmagan), one capsule twice daily. Treatment course duration was 90 days. The control group was composed of 25 healthy individuals. A comprehensive clinical immunological examination was conducted at baseline and on the completion of the treatment course. Enzyme-linked immunosorbent assay kits were used to determine serum levels of immunoglobulins A (IgA), IgM, IgG, and IgE, and cytokines (gamma interferon (IFN-γ) and IL4). Results: At baseline, serum levels of IgA, IgM and IgE were almost twice as high (р = 0.0008; 0.0005; and 0.0001, respectively); IgG, 1.2 times higher (р = 0.001); pro-inflammatory cytokine IL4, 3.5 times higher (р = 0.0001); and anti-inflammatory cytokine IFN-γ, 2.4 times lower (р = 0.0001) in patients with AR and ARC compared to controls, and these differences were significant. Astmagan, when used as an adjunct to the basic treatment of AR and ARC, contributed to 8%, 17%, 16.2%, 7.3% and 6.0% greater decreases in the serum levels of IgA, IgM, IgE, IgG and IL4, respectively, and a 16.6% greater increase in the serum level of IFN-γ compared to the basic treatment only, and these differences were significant, with an improvement in immune response to therapy.","PeriodicalId":16674,"journal":{"name":"Journal of Ophthalmology","volume":"323 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135320490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Мойсеєнко","doi":"10.31288/oftalmolzh202354652","DOIUrl":"https://doi.org/10.31288/oftalmolzh202354652","url":null,"abstract":"The study based on the literature search revealed that the peculiarities of fluid circulation in the posterior part of the eye have been studied insufficiently compared to the anterior part. It is suggested that the retina and optic nerve have their own cleansing system, which functions independently or in interaction with the brain's cleansing system. Of interest is the theory of the glymphatic system of the eye, which probably functions similarly to the glymphatic system of the brain, has four segments and ensures the exchange between intraocular, intracranial and interstitial fluids and the removal of metabolic waste products in the posterior part of the eye. Purpose. To determine the disorders of fluid circulation in the posterior part of the eye in the mechanisms of optic nerve damage development according to the literature. Methods: literature search of 48 sources. It is important to understand that the optic nerve under normal conditions passes a large amount of fluid from the eye to the brain and vice versa. The balance of perfusion (and, presumably, reperfusion in case of pathology) is ensured by the lamina cribrosa, the location of subarachnoid spaces in different parts of the nerve, and the AQP4 channels that support them. The question is whether the optic nerve has its own separate glymphatic system, or whether it interacts with the glymphatic system of the brain. It also remains unclear how the circulation of intraocular fluid, interstitial fluid of the retina and brain, and cerebrospinal fluid in the optic nerve is coordinated with blood, as well as with fluctuations in atmospheric pressure. Although this theory has not yet been recognized, it nevertheless has many supporters who explain optic nerve damage as a result of fluid circulation disturbances. The slowing of fluid flow, as well as the slowing of axonal transport, can be considered as the moment when neuropathy transforms into optic atrophy. That is why the study of the peculiarities of fluid flow and exchange in the posterior part of the eye is important when studying diseases of the optic nerve, whereas the correction of such circulation disorders could be used for therapeutic purposes. Conclusion. Impaired fluid circulation in the posterior part of the eye can occur in mechanisms of optic nerve damage. Improved diagnostics with the ability to assess hydrodynamics will help to understand the role of individual components, while their correction will likely contribute to the optic nerve recovery.","PeriodicalId":16674,"journal":{"name":"Journal of Ophthalmology","volume":"299 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135321534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
