Tyramine pupillometry was performed in 27 cluster headache patients and in 45 healthy controls. Asymmetry variables, i.e. symptomatic(S)-nonsymptomatic(NS) side diameter difference and the ratios (S/NS, log NS/S or S/S+NS) displayed higher sensitivities than variables which express the function of the symptomatic and the nonsymptomatic side pupil separately. Thirty percent of patients had abnormal S-NS values at maximal pupillary dilatation. The statistical properties of different ratio variables are discussed and it is concluded that the transformed ratio (log(NS/S], anisocoria (S-NS) and the anisocoria index (S/S+NS) may be superior to the conventional S/NS ratio.
对27名丛集性头痛患者和45名健康对照者进行了酪胺瞳孔测量。不对称变量，即症状侧（S）-无症状侧（NS）直径差异以及比率（S/NS、log NS/S或S/S+NS）比分别表示症状侧和无症状侧瞳孔功能的变量具有更高的敏感性。30%的患者在瞳孔最大扩张时S-NS值异常。讨论了不同比率变量的统计学特性，并得出结论，转换后的比率（log(NS/S)）、瞳孔不等大（S-NS）和瞳孔不等大指数（S/S+NS）可能优于传统的S/NS比率。
