The content of MMP-9 was found in 281 samples of the tear and 48 samples of BS. The dynamics of MMP-9 in the tear was studied in 55 patients (100 eyes), in BS — in 9 children. The content of TIMP-1 was studied in 173 tear samples and 25 BS samples. The dynamics of TIMP-1 was studied in the tear of 31 patients (56 eyes). The concentration of MMP-9 and TIMP-1 was determined by enzyme immunoassay (ELISA) using the kits ELISA for MMP-9/ELISA for tissue metalloproteinase inhibitor 1 (Cloud clone corporation, USA).Results. The content of MMP-9 in the tear dropped compared to the control group (p = 0.09). The highest content of MMP-9 in panuveitis was found in the tear as compared to the anterior and intermediate uveitis (p = 0.01). The highest MMP-9 concentration was found in cases of 3rd degree of proliferation, in contrast to the 1st and 2nd degrees (p = 0.16). An increased content of TIMP-1 was found in the tear in subactive/intermediate uveitis in contrast to inactive uveitis (p=0.08). An imbalance of MMP-9 was revealed in relation to TIMP-1 in the tears. In the early postoperative period, an increase in the content of MMP-9 and a decrease in TIMP-1 in the tear returning to the initial level was noted, which corresponds to normal wound healing.Conclusion. An increase in the content of TIMP-1 in the tear is associated with subactive/intermediate uveitis. The content of MMP-9 in the tear correlates with the proliferative process stage. A higher MMP-9 content in the tear in panuveitis, in contrast to the anterior and intermediate uveitis is associated with the involvement of all sections of the choroid of the eye into the inflammatory process. The decrease in the content of MMP-9 in the tears is probably explained by the inhibitory effect of glucocorticosteroid (GCS) therapy.","PeriodicalId":21436,"journal":{"name":"Russian Ophthalmological Journal","volume":" 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140384977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A clinical study of 60 patients (120 eyes) with the dry AMD form, aged 55.1 ± 4.2 years, involved 30 patients (60 eyes) aged 52.7 ± 3.9 years with AREDS 2 category (initial AMD stage, group1) and 30 patients (60 eyes) aged 57.9 ± 7.8 years with AREDS 3 category (intermediate AMD stage, group 2). The complex research involved visual acuity measurement, including the assessment of near vision in various illumination conditions according to the authors’ methodology, fluorescein angiography, refractometry, tonometry, optical coherence tomography (OCT), ultrasound duplex scanning of the eye; and an immunological study aimed at determining interleukins and interferons in blood serum.Results. Visual acuity was found to depend on test illumination in healthy subjects and to substantially drop at all illumination levels in AMD, especially in the 3rd stage. With the development of AMD, the activity of the immune response was recorded.The patients of groups 1 and 2 showed an increase in the inflammatory response and a depression of the anti-inflammatory response. In group 1, an increase was recorded in IL-I by 23.5% (p < 0.05), in IL5 by 25.4% (p < 0.05), and in IL8 by 19.9% (p < 0.05). In group 2, the value of these parameters exceeded the norm by 32.1, 39.5 and 25.4% (p < 0.05), respectively. The parameters of anti-inflammatory immunity (IL10 and TGF l) were lower than the reference level by 18.3 and 24.6% (p < 0.05) of patients of group 1 and by 24.3 and 30.75 (p < 0.05) of group 2. It was established that the degree of imbalance of the immune system is associated with the stage of AREDS. In group 2 patients with AREDS 3, the content of pro-inflammatory interleukins exceeded those of group 1: IL-I by 12.5% (p < 0.05), IL5 by 11.9% (p < 0.05), IL8 by 11, 2% (p < 0.05). IL10 and TGF l in group 2 were lower than in group 1 by 10.2 and 11.8% (p < 0.05).Conclusion. Near visual acuity measurement depending on test illumination may be used as a sensitive diagnostic test in AMD in patients. At an early stage of AMD development, a disorder in the immune defense is observed, taking the form of activation of the pro-inflammatory spectrum and depression of the anti-inflammatory component, as well as microcirculatory changes Homeostatic changes of the eye appear at an early stage of the disease and are progressing as the clinical picture is deteriorating. The changes are the greatest at patients with stage 3 of AREDS.","PeriodicalId":21436,"journal":{"name":"Russian Ophthalmological Journal","volume":" April","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140383411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined 132 patients aged 42 to 76 (average age 62.8 ± 2.4 years) who met the classification criteria of ASPDR: impossibility to estimate the area of neovascularization; the fundus of the eye in the posterior pole cannot be seen or can only partialy be seen using an ophthalmoscope; evidence of preretinal or vitreal hemorrhage in the posterior pole with an area of more than 4 optic discs and retinoschisis in the macular zone. All patients were divided into two groups, comparable in age, gender and visual status of the “healthy” eye: the main group (69 eyes), in which VE was performed according to the technique developed by the authors, and the control (63 eyes), in which the traditional VE technique was used. QL was assessed before surgery and 3 months after it using the VFQ-25 and QL-20 questionnaires.Results. QL was found to be higher when the new surgery technique was used: the data of VFA-25 showed a 12.9% increase (p < 0.05) and QL-20 showed a 29.2% increase (p < 0.01), which points to a higher clinical effectiveness of the newly developed surgical treatment technique than that of the traditional technique.Conclusion. The results obtained are related to the ophthalmological features of the developed surgical treatment of ASPDR: combined (phacoemulsification of cataracts + IOL + vitrectomy) one-stage intervention, lack of drainage of subretinal fluid, etc.), medication support (preliminary intravitreal administration of an angiogenesis inhibitor) and anesthesia (intervention under local anesthesia with intravenous sedation).

The study was performed on 20 Chinchilla rabbits, including 16 rabbits in whom the neurodegenerative process in the retina was produced by intravitreal installation of 6-hydroxydopamine (6-OHDA), 0.25 mg per eye, and 4 rabbits (8 eyes) served as control. Thioctic acid 0.5% and Indocollir 0.1% were instilled separately and in combination 5 times daily for 7 days after the injection of 6-OHDA. Pupillary light reaction was estimated and eye fundus condition analyzed. Alpha2-macroglobuline ( 2-MG) and SOD activity, dopamine and protein concentrations were measured in retinal homogenates.Results. Instillations of thioctic acid reduced the retinal damage area almost by half as compared to the untreated group (p d 0.005). Indomethacin was less effective, but the combination of the two drugs brought about a maximal reduction of the damage area (p d 0.05 against the untreated group). Both preparations normalized the disturbed pupillary light reaction. The injection of 6-OHDA caused a decrease of dopamine concentration in the retina (0.050 ± 0.009 pg/mg as against 0.095 ± 0.031 pg/mg in healthy controls, р d 0,05). After instillations of indomethacin and thioctic acid, the concentration tended to increase, and it increased significantly after treatment with their combination (0.141 ± 0.037 pg/mg, p d 0.01 as against untreated animals). The activity of 2-MG in retina decreased after a 6-OHDA injection (2.93 ± 0.42 pg/mg as against 5.5 ± 1.2 pg/mg in healthy controls, р < 0 005) just as they increased the decreased SOD (13.30 ± 5.68 U/mg in healthy controls, 5.41 ± 1.50 U/mg in untreated animals, р < 0.05). Both preparations applied separately or in combination caused a significant increase of 2-MG activity (thioctic acid — 4.19 ± 0.91 pg/mg, indomethacin — 6.95 ± 1.09 pg/mg, combination — 7.25 ± 0.63 pg/mg, р < 0.05 as against the untreated animals) and SOD activity (thioctic acid — 8.25 ± 1.27 U/mg, indomethacin — 29.84 ± 6.63 U/mg, combination — 23.99 ± 3.78 U/mg, р < 0.01 as against the untreated animals).Conclusion.

The study included 75 patients who underwent phacoemulsification with implantation of a posterior chamber intraocular lens. Patients were divided into groups depending on anti-inflammatory treatment: A1 — nepafenac (Nepafenac-Optic), A2 — bromfenac (Broxinac), A3 — dexamethasone (Dexamethasone), B1 — Nepafenac-Optic + dexamethasone, B2 — bromfenac + Dexamethasone. Postoperative inflammation was assessed by the severity of conjunctival hyperemia, pain, Tyndall effect and retinal thickness in the macular region.Results. The severity of the pain symptom was lower in the nepafenac group (A1) as compared to groups A2 and A3 by 49 and 74 %, respectively. A strong direct correlation with the Tyndall effect was revealed, which was more pronounced in group A3 and amounted to 0.73 points. An increase in the thickness of the retina in the macular region in the early stages after surgery was observed in groups A2 and A3, on average by 30 microns. In the groups of Nonpafenac Optic and combined therapy with GCS, the thickness of the retina remained stable. Cystic macular edema in the early postoperative period was observed in groups A2 and A3 and amounted to 2.6 and 1.3 %, respectively. There was a tendency to higher IOP rates in the GCS therapy groups.Conclusion. After surgical treatment of cataracts, the Nepafenac Optic significantly relieves the pain syndrome, as compared with monotherapy with bromfenac or dexamethasone. Nepafenac-Optic helps to reduce the severity of inflammation in the anterior and posterior segments of the eye, minimizes the changes in the retinal thickness of the macular region in the postoperative period. The severity of these effects is comparable to the combination therapy of NSAIDs + GCS. Nepafenac-Optic does not increase IOP, has a more favorable safety profile than in combinations with glucocorticosteroids, and reduces the risk of postoperative complications.","PeriodicalId":21436,"journal":{"name":"Russian Ophthalmological Journal","volume":" 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140387484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
