| 摘 要： | 目的:采用光学相干断层扫描仪(OCT)测量并分析正常人视盘-黄斑中心凹夹角(DFA)测量值及各年龄组、性别、眼别之间的差异。方法:采用光学相干断层扫描仪对正常人198例396眼进行检查,年龄12～60岁,以18岁、40岁为界分为3个不同年龄组,摄取头正位时眼底黄斑中心凹-视盘像,采用ImageJ软件测量DFA数值,应用SPSS统计软件分析数据。结果:正常人DFA变化范围为0.56～14.29度,平均值为7.35±2.15度。正常人各年龄组DFA无显著性差异。右眼及左眼DFA分别为7.43±2.46度和7.27±2.45度,左右眼对比DFA无显著性差异。男性及女性DFA分别为7.41±2.21度和7.28±2.10度,两者间无显著性差异。结论:采用OCT测量正常人DFA为观察眼球旋转角提供了一种新的手段。 |

| Abstract: | ·AIM:To measure disc-fovea angle(DFA)of normal Chinese people with optical coherence tomography(OCT,Carl Zeiss Meditec,Dublin,CA)and investigate the difference.·METHODS:A total of 396 eyes of 198 normal Chinese people were tested by OCT,images of fundus including fovea and disc were photoed,DFA was measured by using ImageJ software,and statistic analysis was done with SPSS software.·RESULTS:DFA of normal Chinese people was 0.56-14.29°,the average value was(7.35±2.15)°.There was no significant difference for DFA among three age groups.DFA of right eye and left eye was(7.43±2.46)° and(7.27±2.45)°respectively,there was no significant difference for DFA between right eye and left eye.DFA of male and female was(7.41±2.21)°and(7.28±2.10)°respectively.There was no significant difference for DFA between male and female.·CONCLUSION:Measurement of DFA by using OCT is a new method of observing the ocular torsion.· |
