PURPOSE
To report and discuss the association between pre- or juxtapapillary arterial loops and tilted disc syndrome (TDS).
OBSERVATIONS
Three patients, aged 43-59 years, with both conditions were examined in a tertiary referral center, and underwent fluorescein angiography, optical coherence tomography (OCT) and/or OCT-angiography. They all presented with a typical inferior staphyloma associated with TDS and anomalies of insertion of retinal vessels. The vascular malformation consisted in one acquired arterial loop or cilioretinal collateral circulation occurring after central artery occlusion, and two more complex pre- and juxtapapillary arterial loops. In all cases, the vascular loops extended inferiorly, in the area of the staphyloma.
CONCLUSION AND IMPORTANCE
We hypothesized that the local anatomical changes in the peripapillary area, observed in eyes with TDS and inferior staphyloma, could have promoted the occurrence and/or extent of the arterial loops.
目的
报告并讨论视乳头前或紧邻视乳头的动脉袢与倾斜盘综合征（TDS）之间的关联。
观察结果
在一家三级转诊中心对3例年龄在43至59岁之间同时患有这两种病症的患者进行了检查，并进行了荧光素血管造影、光学相干断层扫描（OCT）和/或OCT血管造影。他们均表现出与TDS相关的典型下方葡萄肿以及视网膜血管插入异常。血管畸形包括1例在中央动脉阻塞后出现的后天性动脉袢或睫状视网膜侧支循环，以及另外2例更复杂的视乳头前和紧邻视乳头的动脉袢。在所有病例中，血管袢均向下延伸至葡萄肿区域。
结论与意义
我们推测，在患有TDS和下方葡萄肿的眼中观察到的视乳头周围区域的局部解剖学变化，可能促进了动脉袢的发生和/或范围。
