摘要
目的探讨脉络膜炎在吲哚青绿血管造影（ｉｎｄｏｃｙａｎｉｎｅｇｒｅｅｎａｎｇｉｏｇｒａｐｈｙ，ＩＣＧＡ）下的表现特征。方法对１３例（１６眼）脉络膜炎患者均作了ＩＣＧＡ和眼底荧光血管造影（ｆｕｎｄｕｓｆｌｕｏｒｅｓｃｅｉｎａｎｇｉｏｇ－ｒａｐｈｙ，ＦＦＡ）检查。结果ＩＣＧＡ可显示临床和ＦＦＡ所发现不了的脉络膜炎性损害灶，其表现为：①脉络膜血管扩张，扩张的血管呈节段样外观、边缘粗糙；②脉络膜血管通透性增高所致的斑片状强荧光；③脉络膜充盈缺损；④脉络膜炎性水肿所致的异常暗背景荧光；⑤涡静脉扩张。结论ＩＣＧＡ不仅能较好的评价脉络膜炎的血液循环受损程度。
Purpose To study choroidal vascular abnormal characteristics in choroiditis using indocyanine green angiography(ICGA). Methods Thirteen cases(16 eyes)of choroiditis were examined with fundus fluorescein angiography(FFA) and ICGA. Results ICGA findings in choroiditis were as follows:(1)dilatation of choroidal vessels with segmentary appearance and irregular margins;(2)hyperpermeability of choroidal vessels;(3)choroidal filling defects;(4)choroidal hypofluorescence with edema;(5)dilatation of vortex veins. Conclusion ICGA is useful in evaluating the lesions and circulation disturbance of choroiditis which cannot usually be demonstrable in FFA.
