Saccade vergence eye movements: Development, aging, and dysfunction

Eye movements are essential for vision and perception but also forinvestigating brain function, cognition and cerebral plasticity. After a brief presentation of the entire repertoire of eye movements and the techniques for measuring eye movements, I will focus on two types ofeye movements: saccades and vergence, their latency-accuracy-speed and binocular coordination. I will report our research on these aspects in children, adults and aged persons. I will also present our findings on deficits of vergence eye movements and of binocular control in dyslexia, strabismus, vertigo and tinnitus. Finally I will report the interest of eye movements in exploring cognitive impairment in Alzheimer’s disease.


About the speaker

Dr. Kapoula is a research director for the IRIS group at the Hôpital Européen Georges Pompidou, Paris, France. Dr. Kapoulas research focuses on the interaction between vision and postural control, with a special emphasis on development and aging, learning and plasticity effects on oculomotor control. She has published several papers on the topic of binocular control and vergence eye movements. It concerns all eye movements (saccades, pursuit, vergence, fixation, optokinetic nystagmus).
