The authors report five cases of abnormal iris vessels observed in patients, without evident local or systemic pathology. These vessels, are dilated channels. On iris fluorescein angiography their filling appeared earlier than in normal stromal vasculature and was synchronous with that of conjunctival vessels. No dye leakage was present. Two functional angiographic pictures are observable: 1) vessels with abnormal diameter and path, approximately following normal iris vessel arrangement (case 1 and 2); 2) atypical vessels with wide communicating shunt between artery and vein without collaterals (cases 3, 4 and 5). These vessels are very tortuous and do not show any abnormality. The authors suggest to consider these anomalous vessels as anatomic abnormalities comparable with the arterio-venous communications of the retina.
作者报告了5例在患者中观察到的虹膜血管异常病例，这些患者无明显的局部或全身病变。这些血管为扩张的通道。在虹膜荧光血管造影中，它们的充盈比正常基质血管系统更早出现，且与结膜血管的充盈同步。无染料渗漏。可观察到两种功能性血管造影图像：1）直径和走行异常的血管，大致遵循正常虹膜血管排列（病例1和2）；2）动脉与静脉之间有广泛交通分流且无侧支的非典型血管（病例3、4和5）。这些血管非常迂曲，未显示任何异常。作者建议将这些异常血管视为与视网膜动静脉交通相当的解剖学异常。
