目的评价聚类方法应用于趋势分析（逐点线性回归）与逐点线性回归（PLR）的有效性。方法本研究包括101例153只眼开角型青光眼患者。使用PLR，通过以逐点方式外推TD值随时间的变化，使用较短的VF序列（从前3到9）预测第10视野（VF）的总偏差（TD）值。然后，将68个测试点分层为29个扇区。在每个扇区中，计算TD值的平均值并分配给属于该扇区的所有测试点。随后，通过以逐点方式相对于时间外推分配的TD值来预测第10个VF的TD值。进行了类似的分析，以预测第11 - 16个VF使用前10个VFs.ResultsWhen预测第10个VF使用较短的序列，平均绝对误差（MAE）值显着小于在扇区回归比PLR。当预测从第11和第16个VF使用的前10个VF，MAE值显着大于在PLR预测第11 VF时，在扇区回归，但是，没有显着差异观察到与其他VF prediction.ConclusionAccurate预测实现使用扇区回归，特别是当一个小的VF数被用于预测。与PLR相比，在更长的随访期内，扇形回归的准确性没有受到影响。
AimTo evaluate the usefulness of the application of the clustering method to the trend analysis (sectorwise regression) in comparison with the pointwise linear regression (PLR).MethodsThis study included 153 eyes of 101 patients with open-angle glaucoma. With PLR, the total deviation (TD) values of the 10th visual field (VF) were predicted using the shorter VF sequences (from first 3 to 9) by extrapolating TD values against time in a pointwise manner. Then, 68 test points were stratified into 29 sectors. In each sector, the mean of TD values was calculated and allocated to all test points belonging to the sector. Subsequently, the TD values of the 10th VF were predicted by extrapolating the allocated TD value against time in a pointwise manner. Similar analyses were conducted to predict the 11th–16th VFs using the first 10 VFs.ResultsWhen predicting the 10th VF using the shorter sequences, the mean absolute error (MAE) values were significantly smaller in the sectorwise regression than in PLR. When predicting from the 11th and 16th VFs using the first 10 VFs, the MAE values were significantly larger in the sectorwise regression than in PLR when predicting the 11th VF; however, no significant difference was observed with other VF predictions.ConclusionAccurate prediction was achieved using the sectorwise regression, in particular when a small number of VFs were used in the prediction. The accuracy of the sectorwise regression was not hampered in longer follow-up compared with PLR.
