The RT (reaction time) to a 0.25 degree spot of light was measured monocularly on 25 normal subjects and 36 strabismic patients. The overall mean RT and the delta RT (difference in RT between the right and left eyes) for the 19 strabismic patients without amblyopia did not differ significantly from that of the normal subjects. The overall mean RT of the dominant eyes of the 17 amblyopic patients did not differ significantly from that of either the faster of slower eyes of the normal subjects. The overall mean RT of the amblyopic eyes was significantly longer than that of the normal subjects. The delta RT was significantly larger in the amblyopic patients. A regression analysis of the visual acuity of the amblyopic eye and the delta RT showed that the data was best fit by a linear equation. The coefficient of correlation was +0.82. Additional experiments showed that the longer Rt of the amblyopic eyes was not caused by eccentric fixation or by the reduced visual acuity.
对25名正常受试者和36名斜视患者单眼测量了对0.25度光斑的反应时间（RT）。19名无弱视的斜视患者的总体平均RT以及双眼RT差值（delta RT）与正常受试者相比无显著差异。17名弱视患者优势眼的总体平均RT与正常受试者较快或较慢眼睛的总体平均RT相比无显著差异。弱视眼的总体平均RT显著长于正常受试者。弱视患者的双眼RT差值显著更大。对弱视眼视力和双眼RT差值进行回归分析表明，数据最适合线性方程。相关系数为+0.82。额外实验表明，弱视眼较长的RT不是由偏心注视或视力下降引起的。
