Being a highly prevalent neurodegenerative disorder worldwide, Parkinson's disease (PD) shows its complexity not only in the variability of its pathology, but also in the complex constellation of its clinical picture. PD does not affect only the nervous system; instead, it is today recognized as having both motor and non-motor features. The purpose of this article is to report up-to-date information of an ongoing study, which correlates the motor features of Parkinson's disease (PD) with the visual disturbances (non-motor features) related to this disease. Abbreviations: PD = Parkinson's disease, HY = Hoehn-Yahr scale, MMSE = Mini-Mental state exam, UPDRS = Unified Parkinson's disease rating scale, RE = right eye, LE = left eye.
