AIMS
To evaluate angiographic features of myopic crescents using fluorescein angiography (FA) and indocyanine green angiography (IA).
METHODS
FA and IA angiograms of 88 highly myopic eyes (47 consecutive patients) were reviewed. The follow up period ranged from 5-28 years.
RESULTS
FA revealed two zones of the myopic crescent: a consistently hypofluorescent inner zone and an outer zone with delayed choroidal filling. IA revealed dislocation of the Zinn-Haller ring to the border between the two zones. Myopic crescent enlargement occurred in 68.1%. Only the outer zone increased significantly in most of the eyes with enlarged crescents.
CONCLUSIONS
The inner zone might develop as a result of mechanical stretching, and the outer zone might be the result a secondary circulatory disturbance and mechanical stretching.
目的
使用荧光素血管造影（FA）和吲哚菁绿血管造影（IA）评估近视弧形斑的血管造影特征。
方法
回顾了88只高度近视眼（47例连续患者）的FA和IA血管造影片。随访期为5至28年。
结果
FA显示近视弧形斑有两个区域：一个始终低荧光的内区和一个脉络膜充盈延迟的外区。IA显示Zinn-Haller环移位至两个区域之间的边界。68.1%的患者出现近视弧形斑扩大。在大多数弧形斑扩大的眼中，仅外区显著增大。
结论
内区可能是机械性拉伸的结果，外区可能是继发性循环障碍和机械性拉伸的结果。
