The study of vergence movements imperatively needs a recording method. Nowadays, in spite of its various drawbacks, electro-oculography is the most accurate method for clinical wants. The authors have studied the refixation vergence along a symmetrical inducing axis. With regard to both eyes in binocular and monocular fixations the analysis of a great lot of recordings in normal patients allows to reveal some phenomena unknown till now. In binocular fixation it is usual to notice a physiologic dyssynergy of vergence movements. The monocular fixations bear out evidence that Hering's Law doesn't apply to vergence movements. On the contrary they are submitted to a complete opto-motor dissociation, because the motor responses fully change according to the modalities of inducing visual inputs. In others respects, the analysis of all recordings proves that a vergence movement is made up with two synkinetic phases: a slow phase which was known for a long time thanks to physiological laboratory works; but also a fast phase having a saccadic feature. The fast vergence is related with a monocular visual attraction reflex and it is not bound only to the macular function.
对聚散运动的研究迫切需要一种记录方法。如今，尽管存在各种缺点，但眼电图对于临床需求而言仍是最准确的方法。作者研究了沿对称诱导轴的重新注视聚散。关于双眼和单眼注视时的双眼，对大量正常患者记录的分析揭示了一些迄今未知的现象。在双眼注视中，通常会注意到聚散运动的生理性协同失调。单眼注视证明了赫林定律不适用于聚散运动。相反，它们呈现出完全的视动分离，因为运动反应会根据诱导视觉输入的方式而完全改变。在其他方面，对所有记录的分析证明，聚散运动由两个共同运动阶段组成：一个缓慢阶段，由于生理学实验室工作，人们早就知道了这个阶段；还有一个具有扫视特征的快速阶段。快速聚散与单眼视觉吸引反射有关，并且不仅与黄斑功能有关。
