Background:At present, laser is regarded as an effective treatment for macular edema secondary to branch retinal vein occlusion. With the breakthrough of anti-vascular endothelial growth factor drugs in ophthalmology clinical research, the intravitreal injection of ranibizumab is widely applied, but both methods have their limitations, so some clinical studies have combined and applied them together. However, the clinical results are inconsistent and controversial, and there is no relevant system evaluation for the laser combined with intravitreal injection of ranibizumab for treatment of macular edema secondary to branch retinal vein occlusion now.Objective:Meta analysis is used to analyze and evaluate the effectiveness and safety of the laser combined with intravitreal injection of ranibizumab for treatment of macular edema secondary to branch retinal vein occlusion.Method:CNKI, VIP, WANFANG, China Biology Medicine disc, Web of Science, PubMed, Embase, Cochrane Library have used random controlled clinical trial of laser combined with intravitreal injection of ranibizumab for treatment of macular edema secondary to branch retinal vein occlusion from the establishment of the database to October 2020. Two researchers conducted independent screening, quality assessment and data extraction for the literatures, and used RevMan5.3 to conduct Meta analysis for the included literatures.Result:The research has evaluated the effectiveness and safety of the laser combined with intravitreal injection of ranibizumab for treatment of macular edema secondary to branch retinal vein occlusion through the aspects of the best corrected visual acuity 6 months after operation, macular center thickness and the incidence of adverse reactions such as elevated intraocular pressure, endophthalmitis, vitreous hemorrhage and cataract.Conclusion:Laser combined with intravitreal injection of ranibizumab for treatment of macular edema secondary to branch retinal vein occlusion has good effect, and the research has provided reliable evidence for the use of clinical treatment of the laser combined with intravitreal injection of ranibizumab for treatment of macular edema secondary to branch retinal vein occlusion. 相似文献

Rationale:In this paper, we report on 2 patients who developed branch retinal vein occlusion (BRVO) exacerbation 1 day after administration of the BNT162b2 (Pfizer-BioNTech) SARS-CoV-2 vaccine.Patient concerns:Case 1: A 71 year-old female developed vision loss in her left eye 1 day after receiving a second dose of the SARS-CoV-2 mRNA vaccine. This patient was diagnosed with temporal inferior BRVO and secondary macular edema (ME) in her left eye. ME resolved after 3 doses of intravitreal aflibercept (IVA). After treatment, no recurrence of ME was observed.Case 2: A 72 year-old man developed vision loss in his right eye 1 day after receiving the first dose of the SARS-CoV-2 mRNA vaccine. This patient was diagnosed with temporal superior BRVO in the right eye without ME. The patient was followed up and did not undergo any additional treatment.Diagnoses:Case1: Temporal superior BRVO and secondary ME were observed in the left eye. Her best-corrected visual acuity (BCVA) was 20/30.Case2: Temporal superior BRVO recurrence and secondary ME were observed in the right eye. BCVA was 20/25.Interventions:Case1: Additional dose of IVA was administered. Case2: Two times of Intravitreal ranibizumab was administered twice.Outcomes:Case1: Subsequently, ME resolved BCVA was 20/20. Case2: Subsequently, ME resolved BCVA was 20/25.Lessons:Both cases showed a possible association between SARS-CoV-2 vaccination and the exacerbation of BRVO. 相似文献

Background:Central retinal vein occlusion (CRVO) is one of the most common retinal vascular diseases, which is closely related to systemic diseases like hypertension, diabetes and arteriosclerosis. Due of its blinding, it will seriously reduce the quality of life. Macular edema (ME) caused by CRVO is one of the serious complications of visual impairment. We found that the severity of ME in CRVO was positively associated with vascular endothelial growth factor (VEGF) in the anterior chamber. With the accelerated pace of modern life and the changed dietary structure, the incidence of this disease will continue to rise. Therefore, it is of great practical significance to seek effective treatment methods. Intraocular injection of anti-VEGF can effectively alleviate ME and improve visual acuity, showing excellent clinical application prospects. In recent years, there have been some new understandings and advances on the etiology and treatment methods of the present disease, such as the deepening into the molecular biology and gene level. Clinical studies on the efficacy of the disease have emerging. Therefore, a network meta-analysis (NMA) of anti-VEGF treatment for CRVO is particularly necessary to systematically compare its efficacy.Methods:The two reviewers will comprehensively retrieved electronic databases such as PubMed, The Cochrane Library, Wanfang database, Web of Science, Chinese Scientifific Journals Database, EMBASE, China National Knowledge Infrastructure, and China BioMedical Literature. A randomized controlled trial for CRVO against VEGF between January 2010 and June 2021 was included according to the relevant content of the study. In addition, 2 researchers will screen the literature to assess the risk bias for the included articles. We will evaluate the collected evidence and data using a Bayesian NMA method, and analyzed it with STATA and WinBUGS software.Results:Anti-VEGF is one of the effective methods for ME in CRVO patients, accordingly, this study will evaluate its efficacy and safety using a Bayesian NMA system.Conclusion:This study can provide an effective rationale for the clinical application of anti-VEGF for CRVO, contribute to the treatment of CRVO and patient condition rehabilitation in clinical work.Ethics and dissemination:Do not require.INPLASY registration number:INPLASY2021110073. 相似文献

Aim: This study provides a retrospective evaluation of cases with gastric varices secondary to splenic vein occlusion. Methods: Our study group consisted of 14 patients. The clinical manifestations, diagnostic methods and therapeutic modalities were analyzed retrospectively. Results: Eleven patients had co‐existing pancreatic diseases: seven with chronic pancreatitis, three with cancer of the pancreatic body or tail and one with severe acute pancreatitis. Among the three remaining patients, one had advanced left renal cancer, one had myeloproliferative disease and the third had splenic vein occlusion due to an obscure cause. A diagnosis of gastric varices was made following endoscope gastroduodenoscopy or endoscopic color Doppler ultrasonography (ECDUS), and splenic vein occlusions were diagnosed from enhanced computed tomography in all cases. Specific findings of gastric varices secondary to splenic vein occlusion were based on ECDUS color flow images of gastric variceal flow that clearly depicted round cardiac and fundal regions at the center, with varices expanding to the curvatura ventriculi major of the gastric body. For three cases with gastric variceal bleeding, endoscopic injection sclerotherapy using a mixture of histoacryl and lipiodol (70% histoacryl solution) was performed, after which no further bleeding from gastric varices was detected. Due to a high risk of gastric variceal rupture, splenectomy was performed in two cases and splenic arterial embolization in another two cases. Conclusion: ECDUS color flow images of gastric variceal flow depicted specific findings of gastric varices secondary to splenic vein occlusion. Treatment should take into account the diseases underlying these conditions. 相似文献

Retinal vein occlusion (RVO) represents a common cause of visual impairment and blindness. RVO may be associated with both local (e.g., hyperopia, glaucoma) and systemic (e.g., hypertension, diabetes, smoking, obesity, and dyslipidaemia) risk factors. The association with thrombophilia remains controversial. Data on the use of antithrombotic therapy for RVO are poor and inconsistent with most of the information being derived from observational studies. Here we provide a position statement from the Italian Society on Thrombosis and Haemostasis (SISET) to guide the clinical and therapeutic management of patients with RVO based on the available evidence and expert opinion. 相似文献

Retinal vein occlusion is a frequent cause of visual loss for which few effective therapies are available. Anticoagulation with low molecular weight heparin might be of value in its treatment. We conducted a systematic review and meta analysis of randomized trials evaluating the effect of low molecular weight heparin in patients with retinal vein occlusion. Data sources included MEDLINE, EMBASE, HealthSTAR, the Cochrane Library, Lilacs, the Investigative Ophthalmology and Visual Science database and gray literature. Main outcome was the mean difference between the visual acuity measured at baseline and at six months expressed in the logMAR scale. Secondary outcome was a composite of any adverse ocular outcome including: worsening of visual acuity, visual fields or fluorescein angiography, or development of iris neovascularization, any neovascularization or neovascular glaucoma. Subgroup analyses for branch versus central retinal vein occlusion were conducted. We identified 1,084 references of which 3 studies comparing low molecular weight heparin with aspirin (229 evaluable patients) were included. Overall, the pooled mean visual acuity difference was −0.23 logMAR (95% CI −0.38, −0.09; P=0.002) in favor of low molecular weight heparin. Low molecular weight heparin was associated with a 78% risk reduction for developing any adverse ocular outcome (pooled RR 0.22; 95% CI 0.10, 0.46; P<0.001). In subgroup analyses benefits seemed lower in branch retinal vein occlusion. No increased vitreous hemorrhages were observed. In patients with retinal vein occlusion treatment with low molecular weight heparin seems to be associated with improvement in the visual acuity and less adverse ocular outcomes. These benefits might differ in patients with central as opposed to branch retinal vein occlusion. Further studies are required to confirm these findings and clarify its benefits in specific subgroups of patients before definitive recommendations can be made. 相似文献

Background:Recent observations raised concern that the intravenous recombinant tissue plasminogen activator (rt-PA) may result in damage to stroke patients caused by small artery occlusion (SAO). Thus, we perform a protocol for meta-analysis to investigate the efficacy and safety of intravenous thrombolysis with rt-PA in SAO-patients.Methods:The search-style electronic libraries, including Pubmed, Embase, the Cochrane Library, Web of Science, Wanfang Data, VIP Chinese Journals, and China Biomedical Literature Service System are used for document retrieval in June 2021 with no restrictions on language. The risk of bias in include articles will be assessed using the Cochrane Risk of Bias Tool. We perform the meta-analysis by Stata version 10.0 software and calculated the statistics using the inverse variance statistical method. Binary outcomes are presented as Mantel-Haenszel-style risk ratios with 95% confidence interval. Continuous outcomes are reported as mean differences.Results:The results of the article will be shown in a peer-reviewed journal.Conclusion:Intravenous rt-PA may be effective and safe in SAO-patients. 相似文献
