What is blepharospasm?

Spasm of neck muscles
Spasm of facial muscles causing forced eyelid closure
Forced spasm of trunk and pelvic muscles
Spasm of the paravertebral muscles

The correct answer is: Spasm of facial muscles causing forced eyelid closure

Blepharospasm specifically refers to the involuntary and often uncontrollable contraction of the eyelid muscles, leading to forced eyelid closure. This condition is classified as a type of dystonia, which is a movement disorder characterized by sustained muscle contractions. The muscles affected in blepharospasm are primarily those surrounding the eyelids, resulting in symptoms that may vary from mild, occasional blinking to severe and persistent closure of the eyelids, which can impact vision and daily activities. Understanding blepharospasm is critical for emergency nurses, as they may encounter patients experiencing this condition in the ER setting, possibly needing immediate assessment or intervention.
