The associated spasm is an involuntary closure of both eyelids, and attacks last from seconds to minutes with variable periods of relaxation between episodes. It may also be associated with other spasms of the face. Benign Essential Blepharospasm may start with seemingly innocuous winking, blinking or pinching of the face and may cause little or no concern initially. Over time the spasms progress until they cause forceful closure of the eyes, interfering with vision. These spasms can become so severe that they could limit a patient from carrying out his daily activities.
Treatment is available, however.
Injections of a muscle relaxant called Botox can decrease the intensity and frequency of attacks and one series of injections can have lasting effects for months, allowing patients to resume a normal lifestyle.
