Blepharospasm
Blepharospasm
Blepharospasm (pronounced: /ˈblɛfəroʊˌspæzəm/) is a medical condition characterized by involuntary tight closure of the eyelids. The term is derived from the Greek words "blepharon," meaning "eyelid," and "spasm," meaning "an involuntary muscle contraction."
Causes
Blepharospasm is often caused by a malfunction in the basal ganglia, a group of subcortical nuclei in the brain responsible for muscle contractions. Other potential causes include stress, fatigue, or an underlying health condition such as Parkinson's disease or Bell's palsy.
Symptoms
The primary symptom of Blepharospasm is involuntary blinking or eye closure. This can be accompanied by other symptoms such as eye irritation, light sensitivity, or facial spasms.
Treatment
Treatment for Blepharospasm typically involves the use of Botulinum toxin injections to relax the muscles around the eyes. Other treatment options may include medications, surgery, or physical therapy.
