Characterization of Normal and Blepharospasm Blinks by the Eyelid Motion Monitor

We developed the Eyelid Motion Monitor (EMM), a prototype system for monitoring eyelid motion using magnetic fields. We used the EMM to collect clinical data about eyelid motion of Blepharospasm patients - before and after treatment - and to extract characterizing parameters. The effect of the treatmnet, as well as comparison to healthy subjects is discussed.
