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。
