The Role of the Upper Colliculus in the Idiopathic Blepharospasm — COLL-BSP  

Blepharospasm, Benign Essential Clinical Trial

Official title: The Role of the Upper Colliculus in the Idiopathic Blepharospasm : a Pilot Study in Functional MRI

Status Completed

Clinical Trial Summary

This pilot study aims at investigating the role of superior colliculus in patients with idiopathic blepharospasm (BSP) de novo, compared to healthy subjects.

Clinical Trial 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). ;
