高度近视眼的吲哚青绿血管造影

目的探讨高度近视眼的吲哚青绿血管造影(indocyanine green angiography,ICGA)图像特征。方法对27例(54只眼)高度近视眼患者分别进行检眼镜、眼底彩色照相、共焦激光荧光素及吲哚青绿(indocyanine green ,ICG)同步血管造影。结果ICGA显示19只眼有漆裂纹，其中10只眼见漆裂纹中间有点、片状脉络膜新生血管(choroidal neovascularization,CNV)， 占52．6%。而荧光素眼底血管造影(fundus fluorescein angiography,FFA)仅7只眼有明 显的漆裂纹。ICGA与FFA均显示14只眼有多灶性萎缩，ICGA显示3只眼伴有粗大的脉络膜血管 。结论ICGA可更清楚地显示高度近视眼的脉络膜视网膜的变性萎缩、漆裂纹及并发的CNV，有助于预后的评价。(中华眼底病杂志,2001,17:201-203)

Indocyanine green angiography in high myopia

Objective To discuss the image of indocyanine green angiography (ICGA) about high myopia. Methods Tweenty seven patients (54 eyes) with high myopia underwent ocular examination, fundus color photography, simultaneous ICGA and fluorescein angiography (FFA) with the confocal scanning laser ophthalmoscope.The findings for the two modes of amgiographies were compared. Results Lacquer crack was evident on ICGA in 19 eyes among which the focal, plaque choroidal neovascularization (CNV) were apparent in the middle part of lacquer cracks in 10 eyes (52.6%) .In comparison the lacquer cracks were seen in only 7 eyes on FFA. Choroidal capillary atrophy was seen on ICGA and FFA in 14 eyes and ICGA shew thick choroidal vessels in 3 eyes. Conclusion ICGA is superior to FFA for showing choroidoretinal degeneration and atrophy,lacquer crack and CNV in high myopic eyes, and conduce to evaluating prognosis.
