摘要
目的总结2002年7月至2005年3月光动力疗法（PDT）治疗渗出型老年黄斑变性（AMD），重复治疗病例的疗效和临床特点。方法回顾分析渗出型AMD患者78例94只眼采用PDT治疗，患者平均年龄68．4岁，治疗次数为132次，平均1．4次，其中22例30只眼接受重复PDT治疗，占治疗总数31．9％。30只眼共进行PDT治疗68次，其中2次22只眼，占73．3％；3次7只眼，占23．3N；6次1只眼，占3．3％。随诊时间3～32个月，平均随诊时间16．7个月。结果PDT治疗后末次随诊检查时，荧光素眼底血管造影（FFA）或FFA联合吲哚青绿血管造影（ICGA）检查显示CNV渗漏停止14只眼，占46．7％；渗漏减少12只眼，占40％；持续渗漏4只眼，占13．3％。与首次PDT治疗前相比，末次检查矫正视力提高≥2行7只眼，占23．3％；视力波动在上下1行以内14只眼，占43．3％；视力下降≥2行9只眼，占30％。首次PDT后最佳矫正视力13只眼视力提高≥2行，占43．3％；12只眼视力波动在上下1行之内，占40％；5只眼视力下降≥2行，占16．7％。在随诊期中，最佳矫正视力出现在首次PDT后24只眼，占80％；有5只眼出现在2次PDT后，占16．7％；1只眼出现在3次PDT后，占3．3％。结论在重复PDT治疗患者中，末次随诊检查大部分眼CNV能完全或部分闭合，视力提高和维持者占67．8％，最佳矫正视力多出现在首次PDT后，随着PDT治疗次数的增加，最佳矫正视力出现的概率减小。
Objective To summarize the therapeutic effect and clinical characteristics of repetitive photodynamic therapy （PDT） for patients with exudative age-related macular degeneration （AMD）. Methods The clinical data from 78 patients （94 eyes） with exudative AMD who had undergone PDT from July, 2002 to March, 2005 were retrospectively analyzed. The average age of the patients was 68.4, and the treated times was 132 （mean 1.4）. Thirty eyes underwent PDT 68 times, including twice in 22 eyes （73.3%）, 3 times in 7 eyes （23.3%）, and 6 times in 1 eye （3.3%）. The follow-up period lasted 3-32 months with the average of 16. 7 months. Results In the final follow-up examination, the results of fundus fluorescein angiography or combined with indocyanine green angiography showed that the leakage of choroidal neovascularization （CNV） stopped in 14 eyes （46.7%）, reduced in 12 （40%）, and remained in 4 （13.3%）. Compared with the condition before first PDT, the correct visual acuity increased ≥2 lines in 7 eyes （23.3%）, changed ±1 line in 14 eyes （43.3%）, and decreased ≥2 lines in 9 eyes （30%） in the final examination. After first PDT, the best corrected visual acuity increased ≥2 lines in 13 eyes （43.3%）, changed ±1 line in 12 eyes （40%）, and decreased ≥2 lines in 5 eyes （16. 7%）. During the follow-up period, the best corrected visual acuity occurred after first PDT in 24 eyes （80%）, after second PDT in 5 eyes （16.7%）, and after third PDT in 1 eye （3.3%）. Conclusions In patients undergone repetitive PDT, CNV in most of the affected eyes completely or partly closed and the visual acuity improved or remained still in 67.8% of the patients in the final follow-up examination. The best correct visual acuity mainly happened after the first PDT, and as the times of PDT increased, the probability of the best correct visual acuity decreased.
