玻璃体腔注射康柏西普对不同OCT分型糖尿病黄斑水肿的疗效观察

目的：观察玻璃体腔注射康柏西普对不同OCT分型糖尿病黄斑水肿(DME)的疗效差异。

方法：DME患者96例96眼根据OCT形态特征将DME分为弥漫性黄斑水肿(DRT,35眼)、囊性黄斑水肿(CME,33眼)、浆液性视网膜脱离(SRD,28眼),所有患者行玻璃体腔注射0.5mg(0.05mL)康柏西普治疗。治疗后1、3、6mo,比较三组BCVA(LogMAR)、黄斑中心凹视网膜厚度(CFT)、注射次数及视力提高眼数的差异。

结果：随访6mo,三组患眼BCVA呈明显下降趋势(F_时间=205.880,P_时间<0.01),三组间比较有差异(F_组间=3.472,P_组间=0.042),其中DRT组治疗后BCVA改善最佳; 三组患眼CFT呈明显降低趋势(F_时间=392.994,P_时间<0.01),三组间比较有差异(F_组间=5.046,P_组间=0.012),DRT组和CME组的CFT降低程度优于SRD组。随访6mo DRT组的注射次数最少,视力提高眼数比例最高。

结论：玻璃体腔注射康柏西普可显著改善不同OCT分型DME患眼的视力,降低CFT,其中DRT疗效最佳,注射次数最少。     

玻璃体腔注射康柏西普治疗BRVO-ME的疗效及治疗后BCVA的影响因素分析

目的：分析玻璃体腔注射康柏西普治疗视网膜分支静脉阻塞(BRVO)伴黄斑水肿(ME)的疗效及治疗后BCVA的影响因素。

方法：评价2016-01/2018-01在本院接受玻璃体腔注射康柏西普治疗的194例194眼BRVO-ME患者的临床疗效,多因素Logistic回归分析探究治疗后BCVA的影响因素。

结果：患者BCVA(LogMAR)、CMT较治疗前显著下降,其中CMT虽在部分时间节点有回升趋势,但任意时间点的BCVA、CMT均显著低于治疗前(P<0.05); 多因素Logistic回归分析显示,BRVO-ME分型-缺血型、ME类型-混合型、ELM完整性-缺失、IS/OS缺失均是影响BRVO-ME患者经玻璃体腔内注射康柏西普疗效的独立危险因素,且病程及眼轴长度越长、治疗前 BCVA值越高,经玻璃体腔内注射康柏西普治疗无效的风险越高。

结论：玻璃体腔注射康柏西普治疗BRVO-ME疗效显著且安全性良好,部分患者术后BCVA恢复不佳或受病程、术前BCVA、BRVO-ME分型、ELM及IS/OS完整性等因素影响,治疗前或应充分评估上述影响因素并积极应对,优化疗效。     

非缺血型视网膜分支静脉阻塞黄斑水肿抗VEGF治疗的疗效研究

目的：探究雷珠单抗与康柏西普治疗非缺血型视网膜分支静脉阻塞黄斑水肿的疗效及安全性。

结果：治疗后2wk,1、2、3mo,B组患者CMT、CMV、BCVA均明显优于A组(P<0.05)。随访3mo,B组患者视力提高比例显著高于A组(65% vs 38%,P<0.05),玻璃体腔注射次数显著低于A组(P<0.05),但两组患者并发症发生情况(5% vs 0%)无明显差异(P=0.999)。

结论：与雷珠单抗比较,康柏西普治疗非缺血型视网膜分支静脉阻塞黄斑水肿在改善视力,降低CMT和CMV,减少玻璃体腔注射次数方面具有一定优势。

结论：玻璃体内注射康柏西普眼用注射液联合激光治疗糖尿病性黄斑水肿患者有效且安全。     

Intravitreal conbercept injection for neovascular age-related macular degeneration

AIM: To evaluate the efficacy and safety of intravitreal injection of conbercept in patients with neovascular age-related macular degeneration (AMD). METHODS: Retrospective review of 66 eyes of 63 patients with neovascular AMD. All patients received 0.5 mg intravitreal injections of conbercept monthly for 3 consecutive months, and then pro re nata treatment was performed. The changes of best-corrected visual acuity (BCVA) and central macular thickness (CMT) were observed before and after treatments. Minimum follow-up time was 12mo. SPSS 22.0 statistical software was used for statistical analysis. RESULTS: The mean BCVA and CMT of 66 eyes (63 patients) were 1.11±0.60, 533.20±219.95 μm at baseline, and were 0.68±0.38, 310.28±125.60 μm at 3mo. No subjects were lost during the first three months, the improvements were all significantly (P<0.05). During the whole follow-up time of 12mo, 15 subjects (18 eyes) were lost. The mean BCVA and CMT of the rest 48 eyes with the follow-up time at least 1y were 0.83±0.46 and 547.59±196.77 μm at baseline, after 3mo and 12mo of conbercept injections became 0.55±0.41, 318.24±141.29 μm and 0.55±0.51, 333.87±173.25 μm. The differences were significant (P<0.05). No serious complications were observed. CONCLUSION: Intravitreal injection of conbercept appears to significantly improve visual acuity and anatomical outcomes in patients with neovascular AMD, no serious adverse reactions and complications are observed.     

康柏西普治疗老年性黄斑变性的研究现状

老年性黄斑变性( AMD)已经成为发达国家老年人致盲的主要原因之一。随着AMD患者的逐年增加,这也成为眼科防盲研究中重要的课题之一。其病因并不完全清楚,但许多研究表明血管内皮生长因子( VEGF)在其发病中起了重要作用。随着抗VEGF药物的研发与应用,目前已有多种药物应用于该病,本文主要介绍康柏西普在老年性黄斑变性中的应用。     

羟苯磺酸钙联合康柏西普治疗糖尿病性黄斑水肿的疗效和安全性

目的　探讨羟苯磺酸钙联合康柏西普治疗糖尿病性黄斑水肿（diabetic macular edema,DME）的临床疗效和安全性。方法　选取DME患者86例104眼,随机分为康柏西普眼用注射液(conbercept ophthalmic injection,COI)组（43例50眼）和联合组（43例54眼）。COI组给予患者玻璃体内注射COI治疗,联合组在COI组基础上给予患者羟苯磺酸钙胶囊治疗。治疗3个月后,比较两组患者房水血管内皮生长因子（VEGF）、基质细胞衍生因子1（stromal cell derived factor-1,SDF-1）含量以及黄斑中央视网膜厚度（CMT）、最佳矫正视力（BCVA）、并发症发生情况。结果　治疗3个月后,联合组和COI组患者房水VEGF、SDF-1含量均明显低于治疗前,联合组均低于COI组,差异均有统计学意义（均为P<0.05）。治疗1个月、3个月后,联合组和COI组CMT均低于治疗前,且联合组CMT均低于COI组,差异均有统计学意义（均为P<0.05）。治疗1个月、3个月后,联合组和COI组BCVA均明显高于治疗前,联合组BCVA均高于COI组,差异均有统计学意义（均为P<0.05）。治疗中和治疗后,COI组和联合组分别出现眼压升高3眼和2眼,结膜充血各2眼,玻璃体积血各1眼;两组并发症发生率比较,差异无统计学意义（P>0.05）。结论　羟苯磺酸钙联合康柏西普可有效降低DME患者房水VEGF、SDF-1水平,降低CMT,提高BCVA,且安全性好。     

Comprehensive evaluation of intravitreal conbercept versus half-dose photodynamic therapy for chronic central serous chorioretinopathy

AIM: To compare the safety and efficacy of conbercept intravitreal injection and half-dose photodynamic therapy (PDT) in treating chronic central serous chorioretinopathy (CSC). METHODS: This study was retrospective. Thirty-seven patients (37 eyes) with chronic CSC received conbercept injections while 57 patients (57 eyes) were treated with half-dose PDT. All subjects were followed in 6mo. Outcome measures included change in best-corrected visual acuity (BCVA), central macular thickness (CMT), subfoveal choroidal thickness (SFCT), and resolution of subretinal fluid (SRF). RESULTS: There was no adverse event observed in either treatment group. At the 6-month follow-up, 26 eyes (70.3%) in the conbercept group and 54 eyes (94.7%) in the half-dose PDT group (P<0.05) reached full resolution of SRF. The mean logarithm of the minimum angle of resolution (logMAR) BCVA significantly improved (P<0.001) in both treatment groups with better outcome at early phase in the half-dose PDT group (2wk, 1, and 2mo, P<0.05). All subjects experienced significant CMT improvement (P<0.001) with no statistical difference between the two groups (P>0.05). The SFCT also improved in all subjects (P<0.001) with better outcome in the half-dose PDT group (P<0.05). CONCLUSION: Both intravitreal conbercept and half-dose PDT are safe to use in treating chronic CSC. By 6mo, both treatment groups are efficacious in improving BCVA, reducing CMT and SFCT, and resolving SRF in eyes with chronic CSC. Half-dose PDT may show better outcome at initial phase of treatment in chronic CSC. Longer follow-up period is necessary to study for long-term effect and safety.
