Vers une quantification de la dominance oculaire pour une meilleure prise en charge des pathologies de l'œil Quantification of ocular dominance for better management of eye disease

Summary Introduction. — The dominant eye is defined as the one we unconsciously choose when we have perform monocular tasks. In the field of clinical neuro-ophthalmology, it is well-establishedthat ocular dominance plays a key role in several eye diseases. Furthermore, the accurate quan-tification of ocular dominance is crucial with regard to certain surgical techniques. However,classical preoperative tests cannot determine the amount of ocular dominance. Materials andmethods.— Inordertoobtainfurtherinsightintothephenomenonofoculardomi-nance, we study its influence at behavioral and neurophysiological levels (experiments1and 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 oninterhemispheric transfer time. Moreover, we show that an analysis of the dynamics of saccadesallows us to sort out participants with strong or weak ocular dominance. Conclusion. —
