AIMS
To characterise the vasculature of pterygium using indocyanine green (ICG) anterior segment angiography and to demonstrate the pattern of revascularisation following conjunctival autografting.
METHODS
ICG anterior segment angiography was performed on nine patients with pterygium. Angiography was repeated at 1-2 weeks and 2 months following conjunctival autografting in these patients.
RESULTS
Angiography showed a single feeder vessel originating from the anterior conjunctival circulation in six cases (66.7%). This vessel branched to form the radial vessels of the pterygium. Following conjunctival autografting, reperfusion of the vessels in the conjunctival autograft was demonstrable as early as 1 week postoperatively from the episcleral bed. At 2 months postoperatively, the graft appeared well perfused with mild leakage demonstrable at the edges of the graft.
CONCLUSIONS
A single feeder vessel from the anterior conjunctival circulation branches to form the radial vessels in pterygium. Reperfusion of conjunctival autografts occurs as early as 1 week postoperatively from the episcleral bed.
目的
使用吲哚菁绿（ICG）眼前节血管造影术对翼状胬肉的血管系统进行特征描述，并展示结膜自体移植术后的血管再生模式。
方法
对9例翼状胬肉患者进行ICG眼前节血管造影术。在这些患者进行结膜自体移植术后1 - 2周和2个月重复进行血管造影。
结果
血管造影显示6例（66.7%）患者有一条源自结膜前循环的单一供血血管。该血管分支形成翼状胬肉的放射状血管。结膜自体移植术后，最早在术后1周可从巩膜床观察到结膜自体移植片内血管的再灌注。术后2个月，移植片灌注良好，在移植片边缘有轻度渗漏。
结论
来自结膜前循环的单一供血血管分支形成翼状胬肉的放射状血管。结膜自体移植片最早在术后1周从巩膜床开始再灌注。
