中文摘要：

目的探讨50岁以上患者视网膜色素上皮脱离（PED）的眼底改变特征。方法回顾分析2001年10月至2004年8月经荧光素眼底血管造影（FFA）确诊为PED的31例（34只眼）50岁以上连续性病例，眼底改变的特征，患者均进行眼底彩色照相、FFA及吲哚青绿血管造影（ICGA）检查。结果31例34只PED患眼中，FFA显示浆液性PED18只眼，占52．9％，血液性PED8只眼，占23．5％，浆液血液性PED8只眼，占23．5％。ICGA结果显示，12只眼（35．3％）伴发脉络膜新生血管（CNV），17只眼（50．0％）伴发息肉状脉络膜血管病变（PCV），1只眼（2．9％）同时伴发CNV及PCV，4只眼（11．8％）不伴有脉络膜血管性病变。结论50岁以上患者PED可发生于CNV、PCV及无脉络膜血管性病变患眼，其中PCV患眼最常见。

英文摘要：

Objective To investigate the features of ocular fundus of retinal pigment epithelial detachment （PED） in Chinese patients more than 50. Methods The clinical data of 31 continuous patients （34 eyes） with PED diagnosed by ocular fundus photochromy, fundus fluorescein angiography （FFA） and indocyanine green angiography （ ICGA ） from Oct, 2001 to Aug, 2004 were analyzed retrospectively. Results In 34 eyes with PED, the results of FFA showed serous PED in 18 （52.9%）, hemorrhagic PED in 8 （23. 5%）, and serosanguineous PED in 8 （23.5%）; the results of ICGA revealed PED associated with choroidal neovascularization （CNV） in 12 （35.3%）, PED associated with ploypoidal choroidal vasculopathy （PCV） in 17 （50. 0%）, PED associated with both CNV and PCV in 1 （2. 9%）, and avascular PED in 4 （11.8%）. Conclusions PED in Chinese patients more than 50 can be associated with CNV, PCV or other avascular diseases, and PCV is the most common intercurrent choroidal vascular disease.
