The cilioretinal arteries form a physiologic bypass between the ciliary and retinal circulation. The evaluation of photographs of 163 normal optic nerve heads revealed a significant (p less than 0.001) correlation between the number of cilioretinal arteries and the optic disk and cup size: the larger the disk and cup the more vessels. The vessels' prevalence in all optic disks was 27.0%. It increased from 0% in disks smaller than 2.00 mm2 to 50.0% in optic nerve heads larger than 4.1 mm2. No correlations existed between cilioretinal arteries and refraction, axial length, side, sex and age, according to the missing correlations between these parameters and optic disk and cup area. The presence of two or three cilioretinal arteries indicates a congenitally large optic disk and cup in normal eyes, and can be helpful in the differentiation of physiologic macrocups in macrodisks from glaucomatous cupping.
睫状视网膜动脉在睫状循环和视网膜循环之间形成生理性旁路。对163个正常视神经乳头的照片评估显示，睫状视网膜动脉数量与视盘及杯盘大小之间存在显著相关性（p<0.001）：视盘和杯盘越大，血管越多。所有视盘中血管的发生率为27.0%。其发生率从小于2.00 mm²的视盘中的0%增加到大于4.1 mm²的视神经乳头中的50.0%。根据这些参数与视盘及杯盘面积之间不存在相关性，睫状视网膜动脉与屈光、眼轴长度、眼别、性别和年龄之间也不存在相关性。两条或三条睫状视网膜动脉的存在表明正常眼中视盘和杯盘先天性较大，有助于鉴别大视盘中的生理性大杯盘与青光眼性杯盘。
