Abstract： 目的探讨影响光动力疗法(PDT) 治疗脉络膜新生血管(CNV)治疗后患者远视力的相关因素. 方法观察135例(135只眼)行PDT治疗的CNV患者,记录性别、治疗前远视力、治疗前近视力、病程、病因、CNV面积、CNV荧光素眼底血管造影(FFA)分型、CNV治疗后FFA变化等8项因素,运用SPSS统计软件,分别在治疗后1个月和3个月进行视力的多因素相关回归分析. 结果在治疗后1个月内远视力与治疗前远视力、CNV的面积、CNV治疗后FFA变化相关(P=0.000,0.030,0.062);在治疗后3个月与治疗前远、近视力与CNV治疗后FFA变化相关(P=0.000,0.054,0.034);在治疗后1个月内远视力是否提高与 CNV的FFA分型、病程有关(P=0.018,0.080). 结论 CNV面积较小的患者会获得较好的治疗后视力;典型性CNV患者治疗后视力提高的比例较大;对有适应证的患者尽早治疗可能获得较好的视力改善.
