Cilioretinal arteries arise from the short posterior ciliary artery circulation or directly from the choroidal circulation. The presence of a cilioretinal artery may in compromised discs steal flow from the peripapillary circulation and account for worsening glaucoma damage. We reviewed the records of 33 patients with unilateral cilioretinal arteries admitted for investigation of low-tension glaucoma. We looked for absolute difference between the affected and unaffected eyes as well as percent difference relative to the mean value for the two eyes and to the value for the unaffected eye in the following variables: mean defect, corrected loss variance or corrected pattern standard deviation, and adjusted neuroretinal rim area. No statistically significant differences were found. The mean disc area for the eyes with cilioretinal arteries was significantly larger than that previously reported for normal eyes. The results suggest that if vascular steal exists because of the presence of this artery, it is not of major clinical importance.
睫状视网膜动脉起源于睫状后短动脉循环，或直接起源于脉络膜循环。在受损视盘中，睫状视网膜动脉的存在可能会从视盘周围循环中窃取血流，从而导致青光眼损害加重。我们回顾了33例因低眼压性青光眼入院检查的单侧睫状视网膜动脉患者的病历。我们在以下变量中寻找患眼与未患眼之间的绝对差异，以及相对于两眼平均值和未患眼值的百分比差异：平均缺损、校正损失方差或校正模式标准差，以及调整后的神经视网膜边缘面积。未发现统计学上的显著差异。有睫状视网膜动脉的眼睛的平均视盘面积明显大于先前报道的正常眼睛的平均视盘面积。结果表明，即使由于该动脉的存在而存在血管窃取现象，其在临床上也不具有重要意义。
