介绍。 - 主眼被定义为当我们必须执行单眼任务时我们无意识地选择的一只眼睛。在临床神经眼科领域，众所周知，优势眼在多种眼部疾病中起着关键作用。此外，对于某些手术技术而言，准确量化眼优势至关重要。然而，经典的术前测试无法确定优势眼的程度。材料和方法。 - 为了进一步了解眼优势现象，我们研究了它在行为和神经生理学层面的影响（实验1和2）。基于这些新数据，我们提出了一种改进眼部优势量化的方法（实验 3）。结果。 - 我们证明眼优势对手部运动和半球间转移时间有影响。此外，我们表明，对眼跳动态的分析使我们能够筛选出具有强或弱眼优势的参与者。结论。 -总而言之，对眼优势现象的更好理解，再加上扫视动力学的分析，可能在短期或中期内导致建立一组快速、直接的测试，从而确定每位患者的眼优势程度。 (C) 2015 Elsevier Masson SAS。版权所有。
Introduction. - The dominant eye is defined as the one we unconsciously choose when we have to perform monocular tasks. In the field of clinical neuro-ophthalmology, it is well-established that ocular dominance plays a key role in several eye diseases. Furthermore, the accurate quantification of ocular dominance is crucial with regard to certain surgical techniques. However, classical preoperative tests cannot determine the amount of ocular dominance.Materials and methods. - In order to obtain further insight into the phenomenon of ocular dominance, we study its influence at behavioral and neurophysiological levels (experiments 1 and 2). Based on these new data, we suggest a method to improve quantification of ocular dominance (experiment 3).Results. - We demonstrate that ocular dominance has an influence on hand movements and on interhemispheric transfer time. Moreover, we show that an analysis of the dynamics of saccades allows us to sort out participants with strong or weak ocular dominance.Conclusion. - In conclusion, this better understanding of the phenomenon of ocular dominance, coupled with the analysis of saccadic dynamics, might, in the short or medium term, lead to the establishment of a quick and straightforward battery of tests allowing determination of the amount of ocular dominance for each patient.
