Abstract： 目的观察老年性黄斑变性(age-related macular degeneration ,AMD)的脉络膜新生血管(choroidal neovascularization,CNV)与黄斑区脉络膜分水带(choroidal watershed zones,CWZ)的关系. 方法对比分析AMD 患者57例57只眼以及与之年龄相匹配的无AMD的患者35例35只眼的吲哚青绿血管造影(indocyanine green angiography, ICGA)资料,观察CNV与黄斑区CWZ的关系. 结果 57只AMD眼中,35只眼有黄斑区CWZ,占61.4%;对照组35只眼中,3只眼有黄斑区CWZ,占8.57%,两者比较差异有显著性的意义(P＜0.05).在有CNV的43只渗出型AMD眼中,32只眼有黄斑区CWZ,占74.4%,其中29只眼的CNV来自黄斑区CWZ,占90.6%. 结论黄斑区CWZ可能是渗出型AMD的CNV好发部位.
