Summary
This pilot study aims at investigating the role of superior colliculus in patients with idiopathic blepharospasm (BSP) de novo, compared to healthy subjects.
Detailed description
The objective of the study is to investigate the function of the superior colliculus (SC) related to visual stimulation by means of fMRI (functional magnetic resonance imaging) in patients with idiopathic BSP compared to healthy subjects. The hypothesis is that SC function is impaired in BSP (role of biomarker of SC).
