The reproducibility of optic disc cup measurements was analyzed in 24 eyes of 24 patients [8 normals, 8 glaucoma patients, 8 glaucoma suspects] using the Laser Tomographic Scanner. The mean coefficient of variation in triple measurements was 5.0% for the cup area, 5.4% for the rim area, 7.0% for the cup volume, 4.0% for the mean cup depth, and 4.3% for the maximum cup depth. Mean reliability between two of the three measurements performed in each eye was better than 0.988 for the cup area, 0.995 for the cup volume and 0.996 for the mean cup depth readings. These results suggest that laser scanning tomography allows highly reproducible measurements in living eyes and adds an important tool to the ophthalmologist's armamentarium for the diagnosis and follow-up of glaucoma patients.
使用激光断层扫描仪对24例患者的24只眼睛[8例正常人、8例青光眼患者、8例青光眼疑似患者]的视盘杯测量的可重复性进行了分析。三次测量的平均变异系数杯面积为5.0%，边缘面积为5.4%，杯体积为7.0%，平均杯深度为4.0%，最大杯深度为4.3%。每只眼睛进行的三次测量中的两次之间的平均可靠性，杯面积优于0.988，杯体积优于0.995，平均杯深度读数优于0.996。这些结果表明，激光扫描断层扫描可在活体眼中进行高度可重复的测量，并为眼科医生诊断和随访青光眼患者的手段增添了一项重要工具。
