我们使用了一个人类眼睛的塑料模型来研究视神经头分析仪估计视神经头的表面轮廓和二维尺寸的准确性。计算机生成的轮廓线与扫描电子显微镜拍摄的塑料杯的实际横截面轮廓相似。计算机测量的髋臼杯直径的放大误差与模型的轴向长度呈负相关。通过使用折射或轴长作为放大误差的校正因子,该关系的斜率减小。在两个校正因子中,前者提供了有晶状体模型中已知直径的最接近估计,而后者在无晶状体模型中表现更好。
We used a plastic model of the human eye to study the accuracy with which the Optic Nerve Head Analyzer estimates the surface contour and two-dimensional size of the optic nerve head. Computer-generated contour lines were similar to the actual cross-sectional contour of plastic cups as photographed by scanning electron microscopy. The magnification error of computer-measured cup diameters was inversely related to the axial length of the model. The slope of this relationship was reduced with the use of either refraction or axial length as a correction factor for magnification error. Of the two correction factors, the former provided the closest estimation of the known diameters in the phakic model, while the latter performed better in the aphakic model.
