简介:目的:比较雷珠单抗和光动力疗法(photodynamictherapy,PDT)治疗湿性年龄相关性黄斑变性(age-relatedmaculardegeneration,AMD)的临床疗效。方法:回顾性分析23例PDT治疗的湿性AMD患者和23例予雷珠单抗玻璃体腔内注射治疗的湿性AMD患者的资料,比较两组在治疗后1,3,6mo的视力、OCT及FFA变化情况。结果:两组患者术后1,3mo视力均得到明显提高,两组在统计学意义上无显著差异,雷珠单抗组有2例(9%)患者在治疗后6mo出现视力回降现象,PDT组患者在术后3mo及术后6mo视力变化稳定。结论:雷珠单抗和PDT治疗湿性AMD,均能有效控制湿性AMD患者病情发展并能改善患者视力,两种疗法疗效的比较在短期内无统计学意义,但是术后6mo,PDT的稳定性优于雷珠单抗。
简介:研究显示,趋化因子受体3(chemokinereceptor3,CCR3)在眼部主要分布于视网膜色素上皮细胞中,亦表达于脉络膜血管内皮细胞(CECs)中。CCR3的特异性高表达在湿性年龄相关性黄斑变性(age-relatedmaculardegeneration,AMD)中被发现,并被证明在湿性AMD患者脉络膜新生血管(choroidalneovascularization,CNV)的产生中具有重要作用。本文拟对CCR3的结构、功能、目前研究存在的问题及未来的研究方向做一综述。相信随着对CCR3研究的进一步深入,必将帮助我们寻找到一种湿性AMD诊断和治疗的新方法,同时也可能对其它CNV性疾病研究以及新的抗CNV药物提供重要参考。

简介:目的探讨自拟补肾通络明目汤对青光眼术后视神经功能的影响。方法将2015年8月至2018年1月我院接诊的122例患者纳入本研究。利用随机号码表抽取样本,均分为观察组和对照组各61例。对照组:1%卡替洛尔滴眼液控制眼压。观察组:1%卡替洛尔滴眼液控制眼压配合自拟补肾通络明目汤治疗。观察视力、眼压、视野、RNFL变化情况。结果观察组和对照组治疗前后视力和眼压对比,P〉0.05;观察组治疗后MD、PSD、MS均低于治疗前和对照组(P〈0.05);观察组治疗后RNFL颞侧、上方、下方均高于对照组治疗后(P〈0.05)。结论自拟补肾通络明目汤对青光眼术后视神经功能有积极影响,对患者视力和眼压无明显影响,能够降低MD、PSD、MS水平,提高RNFL颞侧、上方、下方水平。
