AIM
To estimate the incidence of cilioretinal arteries among Han population of north China.
METHODS
A cross-sectional sample of subjects aged from 20 years old to 80 years old were selected using a cluster sampling technique from Shenyang of Liaoning Province for Diabetic Eye Disease Study. Eligible subjects were recruited in the Community Health Center which took the stereo fundus photography using 45°Non-Mydriatic Fundus Camera. Data were analyzed by SPSS 14.0.
RESULTS
The incidence of cilioretinal arteries in 5000 eyes of 2500 subjects was determined. One, two or more cilioretinal arteries were present in 876 of all subjects and in 923 of all the eyes. Difference of presence, number and distribution of cilioretinal arteries was observed. During the subjects, the arteries occurred bilaterally in 6.9% and contributed to some portion of the temporal circulation in 78.3%, nasal circulation 14.8%, respectively. Statistical analysis indicated that there was no significant difference in incidence between men and women, left and right eyes (P>0.05).
CONCLUSION
35.0% persons have the cilioretinal arteries in Han population of north China. Men and women have an equal distribution of cilioretinal arteries.
目的
评估中国北方汉族人群中睫状视网膜动脉的发生率。
方法
采用整群抽样技术，从辽宁省沈阳市选取年龄在20岁至80岁之间的受试者作为糖尿病眼病研究的横断面样本。符合条件的受试者在社区卫生中心招募，该中心使用45°免散瞳眼底照相机进行立体眼底摄影。数据采用SPSS 14.0进行分析。
结果
确定了2500名受试者5000只眼中睫状视网膜动脉的发生率。所有受试者中有876人、所有眼中有923只眼存在一条、两条或更多条睫状视网膜动脉。观察到睫状视网膜动脉在存在、数量和分布上的差异。在受试者中，动脉双侧出现的占6.9%，分别参与颞侧循环的比例为78.3%，鼻侧循环的比例为14.8%。统计分析表明，男女之间、左右眼之间的发生率无显著差异（P>0.05）。
结论
中国北方汉族人群中35.0%的人有睫状视网膜动脉。男女睫状视网膜动脉分布均等。
