The Heidelberg Retina Tomograph (HRT) was intended to evaluate the optic nerve head. It is, however, also possible to measure retinal elevations. There are no systemic data on the reproducibility of HRT measurements of retinal elevations. We now provide such data.
117 measurements in patients with diseases which are characterized by retinal elevations were analyzed with the HRT. We measured the "volume above surface" of the retinal elevations. Each patient was analyzed three times, and the coefficient of variation was calculated.
The coefficient of variation was between 0.55% and 40.5%. Some 42% of the coefficients of variation were between 0% and 10%, 31% between 5% and 10%, 21% between 10% and 20%, and 6% larger than 20%.
The reproducibility of the HRT measurements in retinal elevations is clinically sufficient. The relation between sufficient reproducibility and accuracy is discussed.
海德堡视网膜断层扫描仪（HRT）旨在评估视神经乳头。然而，它也能够测量视网膜隆起。目前尚无关于HRT测量视网膜隆起重复性的系统性数据。我们现提供此类数据。
使用HRT对117例以视网膜隆起为特征的疾病患者的测量结果进行分析。我们测量了视网膜隆起的“表面上方体积”。每位患者均接受三次分析，并计算变异系数。
变异系数在0.55%至40.5%之间。约42%的变异系数在0%至10%之间，31%在5%至10%之间，21%在10%至20%之间，6%大于20%。
HRT测量视网膜隆起的重复性在临床上是足够的。文中讨论了足够的重复性与准确性之间的关系。
