BACKGROUND Corneal neovascularization(CoNV)is the second major cause of blindness.Vascular endothelial growth factor(VEGF)inhibitors,e.g.,bevacizumab,have been used to prevent CoNV.AIM We conducted an updated systematic review and meta-analysis of clinical trials to examine the efficacy and safety of anti-VEGF in CoNV.METHODS A literature search was conducted using three electronic databases.Mean difference(MD),standard mean difference(SMD),and relative risk(RR)are used to estimate the effect size.RESULTS Nine randomized controlled and three non-randomized trials were obtained.The pooled results demonstrated a significant reduction of CoNV area/Length(SMD=-1.17,95%CI:-1.58 to-0.75),best corrected visual acuity(MD=-0.54,95%CI:-0.91 to-0.17),and graft rejection(RR=0.44,95%CI:0.24 to 0.8)and failure(RR=0.39,95%CI:0.19 to 0.78)rates in the anti-VEGF group than the placebo group.A non-significant reduction of the epithelial defect was also observed in the bevacizumab group compared with the placebo(RR=0.56,95%CI:0.30 to 1.06).Compared with a placebo,the unsynthesizable trials also support that bevacizumab improves visual acuity,CoNV,graft rejection,and failure rates.Trials reporting other comparisons revealed the superiority of combined remedy with bevacizumab compared to other treatments in reducing CoNV.CONCLUSION Anti-VEGF agents,mainly bevacizumab,are an effective and safe treatment for CoNV of all causes and prevent corneal graft rejection and failure in corneal transplantation. 展开更多

BACKGROUND Intravitreal anti-vascular endothelial growth factor(IVA)injection is known to cause contraction of fibrovascular proliferation(FVP),when present in severe retinopathy of prematurity(ROP).AIM To assess the structural outcomes of IVA injection in the treatment of severe posterior ROP with significant FVP.METHODS It was a retrospective study in which 36 eyes of 18 preterm babies who developed>4 clock hours of FVP in zone I or posterior zone II,were treated with either intravitreal 0.625 mg bevacizumab or intravitreal 0.2 mg of ranibizumab.Favorable structural outcome included resolution of plus disease and FVP without the development of tractional retinal detachment.Secondary outcome measure included either full retinal maturation at follow-up or development of recurrent disease requiring additional treatment.Adverse outcomes included progression to retinal detachment.RESULTS The mean gestational age of the 18 preterm babies was 30 wk(range 27-36),and mean birth weight was 1319 g(range 650-1980 g).Mean post-menstrual age(PMA)at the time of primary treatment was 35.5 wk(range 31-41 wk).All eyes showed regression of plus disease and FVP.5 eyes of 3 babies showed reactivation of disease and were treated with repeat IVA(n=2 eyes)or peripheral laser photocoagulation(n=3 eyes)respectively.16 out of 36(44%)reached retinal vascular maturation at final follow up at 5 years.CONCLUSION There was good resolution of severe posterior ROP with FVP with IVA,with retinal maturity of 44%at 5 year follow-up and a reactivation rate of 13.8%.When the IVA injection is given prior to 37 wk PMA,while disease is in phase 2,it is less likely to cause contracture of pre-existing FVP. 展开更多

AIM: To investigate the difference in activation of STAT3 signaling between two human stomach adenocarcinoma cell lines: 5-fluorouracil resistant cell line and its parental cell line, and to evaluate its relationship with the expression of vascular endothelial growth factor (VEGF). METHODS: Western blot and electrophoretic mobility shift assay (EMSA) were used to detect the expression of phospho-STAT3 protein and constitutive activation of STAT3 in two human stomach adenocarcinoma cell lines, 5-fluorouracil resistant cell line SGC7901/R and its parental cell line SGC7901, respectively. The mRNA expression of VEGF was analysed by semi-quantitative RT-PCR. The expressive intensity of VEGF protein was measured by immunocytochemistry. RESULTS: The expressions of phospho-STATS protein and constitutive activation of STAT3 between two human stomach adenocarcinoma cell lines were different. Compared with the parental cell line SGC7901, the STAT3DNA binding activity and the expressive intensity of phospho-STAT3 protein were lower in the drug-resistant cell line SGC7901/R. The expression levels of VEGF mRNA and its encoded protein were also decreased in drugresistant cell line. CONCLUSION: Over-expression of VEGF may be correlated with elevated STAT3 activation in parental cell line. Lower VEGF expression may be correlated with decreased STAT3 activation in resistant cell line, which may have resulted from negative feedback regulation of STAT signaling. 展开更多

AIM:To explore the efficacy of minimally invasive vitrectomy(MIV)with or without internal limiting membrane(ILM)peeling on the treatment of diabetic macular edema(DME)in proliferative diabetic retinopathy(PDR)combining with preoperative anti-vascular endothelial growth factor(anti-VEGF)injection.METHODS:Totally 132 eyes(132 patients)diagnosed PDR with DME were included between June 2015 and June 2018 in Tianjin Eye Hospital.The single MIV treatment group included 68 eyes and the MIV combined with ILM peeling group included 64 eyes.Anti-VEGF drugs were injected intravitreally 1wk before the operation and the period of follow-up was 1 to 3y.Best-corrected visual acuity(BCVA),central retinal thickness(CRT),total macular volume(TMV),macular edema(ME)severity,intraocular pressure(IOP),and complications were recorded.Prognostic factors of visual acuity following ILM peeling were analyzed.RESULTS:The BCVA was higher than preoperative values at 1,3,6,and 12mo after surgery in both groups(all P<0.05).At 6 and 12mo,the BCVA of the combined group was significantly higher than that of the MIV only group(0.52±0.23 v/s 0.64±0.29 IogMAR,P=0.011 in 6mo;0.41±0.25\/s 0.52±0.25 IogMAR,P=0.008 in 12mo).Mean CRT values postoperative were significantly lower than preoperative values in both groups from the 1^(st) month(lmo 397.65±106.18 vs 451.94±118.88 μm in MIV only group;388.88±108.68 v/s 464.36±111.53 μm in combined group;both P<0.05)and decreased gradually.The differences between the two groups were statistically significant at 3,6,and 12mo(P=0.004,0.003,0.00 respectively).The TMV was decreased from the 3^(rd) month in the single treatment group(3mo 11.14±1.66 vs 12.20±2.09 mm^(3),P<0.05).At 12mo,the proportion of eyes with edema that had CRT more than 350μm was significantly lower than before surgery(13.24%vs 77.94%in MIV only group;1.56%vs 81.25%in combined group;both P<0.05).There was no significant difference in the recurrence incidence of macular epiretinal membrane,ME,transient IOP increase,vitreous rebleeding,or traction retinal detachment between the two groups.BCVA after ILM excision was positively correlated with the CRT and ME degree before and after surgery(r=0.430,0.485,respectively;P<0.05).CONCLUSION:MIV combined with ILM peeling accelerates the absorption of ME,improves vision,reduces the postoperative CRT and TMV,and reduces the recurrence rate of postoperative ME. 展开更多

AIM: To evaluate the outcomes of intravitreal antivascular endothelial growth factor(anti-VEGF) agents for patients with retinal vein occlusion(RVO) related-macular edema(ME) in Tibetan.METHODS: A retrospective, observational, single-center study. The demographic and clinical data of 90 RVO Tibetan patients(93 eyes) treated with either ranibizumab or conbercept in Tibet Autonomous Region People’s Hospital from Jan 2018 to December 2019 were collected.RESULTS: The mean patient age was 56.8±10.6y, 45(50%) of them were female. The mean living altitude was 3867.8±567.9 m. At the last visit, the best-corrected visual acuity(BCVA) significantly increased(52.2±21.8 letters) in comparison with the baseline(38.2±24.1 letters, P<0.001);while the central retinal thickness(CRT) significantly reduced(245.5±147.6 μm) in comparison with the baseline(504.1±165.2 μm, P<0.001). The 43.0% of the eyes gained≥15 letters, 60.2% of the eyes gained ≥10 letters, and 78.5% of the eyes gained ≥5 letters. No vision loss was noted in 92.5% of the eyes, 4 eyes lost more than 10 letters during follow-up period. The mean number of injections was 2.4±1.8. No severe ocular or systemic adverse events related to either the drug or injection were noted.CONCLUSION: Anti-VEGF therapy is effective and safe in Tibetan patients for the treatment of RVO related ME. 展开更多

Diabetic retinopathy(DR)is the most common cause of visual loss among working age individuals.Diabetic macular edema(DME)is an important complication of DR that affects around one third of the patients with DR.Several treatments have been approved for DME ranging from blood pressure and glycemic control to photocoagulation and more recently the use of vascular endothelial growth factor(VEGF)antagonists.The index review discusses aflibercept(EYLEA-Regeneron Pharmaceuticals,Inc.,Tarrytown,New York,NY,and Bayer Healthcare Pharmaceuticals,Berlin,Germany)in the context of other VEGF antagonists currently available for the treatment of DME.A systematic search of literature was conducted on PubMed,Scopus,and Google Scholar with no limitation on language or year of publication.Pre-clinical studies of aflibercept have shown a higher affinity of this molecule for vascular endothelial growth factor A(VEGF-A)along with a longer duration of action as compared to other VEGF antagonists.Recent clinical trials have shown visual outcome results for aflibercept to be similarly favorable as compared to other available agents with the added benefit of fewer required injections and less frequent monitoring.Aflibercept presents a potential exciting new addition to the armamentarium of current VEGF antagonists available for the treatment of DME and other retinal vascular diseases.However,further studies are indicated to confirm the role,safety,and efficacy of aflibercept for DME. 展开更多

Diabetic retinopathy is one of the prominent causes of vision impairment in the working-age population in industrialized countries and is related to 1%-5% of cases of blindness in the world. Among patients with diabetic retinopathy, diabetic macular edema(DME) is the major reason of vision impairment and represents a significant public health problem. Previous studies demonstrated the role of vascular endothelial growth factor(VEGF) in diabetic retinopathy and DME pathogenesis, and also revealed the efficacy of anti-VEGF agents for the management of these disorders. This review summarizes the outcomes of clinical studies that evaluated the anti-VEGF therapy including pegaptanib, ranibizumab, bevacizumab, and aflibercept for the management of DME. A significant number of clinical trials indicated favorable functional and anatomical results of anti-VEGF therapy for DME. Therefore, these agents should be considered an option in the treatment of DME in routine clinical practice. 展开更多

AIM:To describe the multimodal imaging features,treatment,and outcomes of patients diagnosed with adultonset Coats disease.METHODS:This retrospective study included patients first diagnosed with Coats disease at≥18 years of age between September 2017 and September 2021.Some patients received anti-vascular endothelial growth factor(VEGF)therapy(conbercept,0.5 mg)as the initial treatment,which was combined with laser photocoagulation as needed.All the patients underwent best corrected visual acuity(BCVA)and intraocular pressure examinations,fundus color photography,spontaneous fluorescence tests,fundus fluorescein angiography,optical coherence tomography(OCT),OCT angiography,and other examinations.BCVA alterations and multimodal image findings in the affected eyes following treatment were compared and the prognostic factors were analyzed.RESULTS:The study included 15 patients who were aged 24-72(57.33±12.61)y at presentation.Systemic hypertension was the most common associated systemic condition,occurring in 13(86.7%)patients.Baseline BCVA ranged from 2.0 to 5.0(4.0±1.1),which showed improvement following treatment(4.2±1.0).Multimodal imaging revealed retinal telangiectasis in 13 patients(86.7%),patchy hemorrhage in 5 patients(33.3%),and stage 2B disease(Shield’s staging criteria)in 11 patients(73.3%).OCT revealed that the baseline central macular thickness(CMT)ranged from 129 to 964μm(473.0±230.1μm),with 13 patients(86.7%)exhibiting a baseline CMT exceeding 250μm.Furthermore,8 patients(53.3%)presented with an epiretinal membrane at baseline or during follow-up.Hyper-reflective scars were observed on OCT in five patients(33.3%)with poor visual prognosis.Vision deteriorated in one patient who did not receive treatment.Final vision was stable in three patients who received laser treatment,whereas improvement was observed in one of two patients who received anti-VEGF therapy alone.In addition,8 of 9 patients(88.9%)who received laser treatment and conbercept exhibited stable or improved BCVA.CONCLUSION:Multimodal imaging can help diagnose adult-onset Coats disease.Anti-VEGF treatment combined with laser therapy can be an option for improving or maintaining BCVA and resolving macular edema.The final visual outcome depends on macular involvement and the disease stage. 展开更多

Study selection Clinical trials and case studies presented at medical conferences and published in peer-reviewed literature in the past decade were reviewed. Results Anti-VEGF agents have manifested great potential and promising outcomes in treating ocular neovascularization, though some of them are still used as off-label drugs. Intravitrea~ injection of anti-VEGF agents could be accompanied by devastating ocular or systemic complications, and intimate monitoring in both adult and pediatric population are warranted. Future directions should be focused on carrying out more well-designed large-scale controlled trials, promoting sustained duration of action, developing safer and more efficient generation of anti-VEGF agents. Conclusions Anti-VEGF treatment has proved to be beneficial in treating both anterior and posterior neovascular ocular diseases. However, more safer and affordable antiangiogenic agencies and regimens are warranted to be explored. 展开更多

Objective: To evaluate the effect of anti-vascular endothelial growth factor (VEGF) on juxtafoveal choroidal neovascularization (CNV) secondary to multifocal choroiditis (MFC) and wet age-related macular degeneration (AMD). Methods: In this retrospective, comparative study, 20 unique eyes with CNV were divided into two groups: 10 patients affected by MFC and 10 patients diagnosed with wet AMD. They all received local intravitreal (Ivr) injections of ranibizumab, with 6 months of follow-up. Retreatment injections were performed based on findings suggestive of active neovascularization. Results: Significant improvements were observed in the juxtafoveal CNV lesions, and average central macular thickness decreased in both groups following the anti-VEGF therapy (P〈0.05). The average number of injections used in MFC patients was 1.6, while three injections on average were used in wet AMD patients (Z=-2.844, P=0.009). Best-corrected visual acuity was significantly improved in MFC patients after anti-VEGF therapy (P〈0.05), and there was no significant difference in wet AMD patients between before anti-VEGF therapy and 6 months later (P〉0.05). Conclusions: IVT ranibizumab resulted in good clinical outcomes for juxtafoveal CNV secondary to MFC and wet AMD, but the average number of injections used in MFC was fewer than that used in wet AMD over a 6-month observation period. Compared with the wet AMD group, visual acuity was obviously improved in the MFC group at 6 months. 展开更多
