Evaluation of ocular blood flow by Doppler ultrasound in patients with essential blepharospasm.

In conclusion, our study suggested that ocular spasm in patients with EB had no effect on blood flow other than SOVBFV. When SOVBFV was compared between the EB and control groups, it was found to be increased in the EB group. We consider that this statistical difference may be clinically and pathophysiologically significant.
