Brief Summary

This study aims to study, in patient with Parkinson's disease, mild to moderate stage (according to Movement Disorder Society Clinical Diagnostic Criteria for Parkinson's Disease, Postuma et al., 2015): * the evolution of oculomotricity markers over time. * the correlation between neurological evaluations (motor and non-motor scores), neuropsychological evaluations (cognitive disorders) and oculomotricity evaluation, over a follow-up period of 7 years. * the impact of antiparkinsonian drugs on the evolution of oculomotricity assessment by video-oculography. * the value of oculomotricity assessment by video-oculography as an evolutionary marker of the disease.
