中文摘要：

目的利用频域光学相干断层扫描（SD—OCT）和眼底彩色照相方法测量青光眼视盘旁萎缩区，并比较二者结果的一致性。方法连续收集就诊于中国医科大学附属第一医院眼科的青光眼患者30例（54只眼），进行视盘SD—OCT检查和眼底彩色立体照相。分别测量以视盘为中心6条子午线上视盘旁萎缩区13区宽度并计算平均值，比较2种检查结果的相关性，并进行一致性评价。结果使用眼底彩色照相法和SD—OCT检查法测量青光眼患者眼底视盘旁萎缩区B区平均宽度分别为（229．89±99．82）μm和（224．14±97．10）μm，二者比较无统计学差异（P=0．280）。2种检查方法结果具有高度相关性（r=0．825，p〈0．001），二者间具有良好的一致性（ICE=0．923，95％CI0．870。0．954）。结论利用SD-OCT法与眼底彩色照相法测量青光眼视盘旁萎缩区G区结果具有良好的一致性，可以利用SD-OCT方法测量青光眼视盘旁萎缩区p区。

英文摘要：

Objective To measure peripapillary atrophy （PPA） in glaucoma with high- resolution spectral domain-optical coherence tomography （SD-OCT） and conventional color fundus photograph, and compare the consistency of the results between the two irnaging methods. Methods Ato- tal of 30 patients （54 eyes）with glancoma from Department of Opthalroology, the First Hospital, China Medical University were prospectively includ- ed for the study. SD-OCT images and color fundus photographs taken through the region of PPA were qualitatively analyzed. The average width of 13- PPA area in 6 reference lines centered optic nerve were measured using SD-OCT and color fundus photograph. Correlation and agreement between the two measuring methods were analyzed. Results The average width of β- PPA was 229.89± 99.82 μm using color fundus photographs and 224.14±97.10 μm using SD-OCT, respectively. There was no significant difference （P = 0.280）. The correlation coefficient was 0.825 between re- sults measured by SD-OCT and color fundus photographs for β-PPA area （P 〈 0.001 ）, and agreement between the two methods was good （ICC= 0.923,95% CI 0.870-0.954）. Conclusion The correlation and consistency is good between SD-OCT and conventional color fimdus photograph measuring β-PPA area. β-PPA area can be estimated with SD-OCT.
