What Is Blepharospasm?

Blepharospasm is a condition known as eyelid spasm. It is characterized by involuntary, repetitive and abnormal contractions of the muscles that control the eyelids.

It is usually seen in both eyes and may cause a person to blink frequently or close their eyes involuntarily. This condition may range from mild discomfort to severe eye spasms.

Important Information: Eyelid spasms may be temporary, but they can also be a sign of blepharospasm that affects daily life. If symptoms recur frequently, affect vision or become prominent in both eyes, an ophthalmologist should be consulted.

What Causes Blepharospasm?

Stress and fatigue, dry eye or infections, abnormalities in brain nerve pathways and neurological diseases such as Parkinson’s disease may be among the causes of blepharospasm.

In some people, blepharospasm may develop without a clear cause. In some cases, it may be associated with eye surface irritation, sensitivity to light, medications being used or neurological diseases.

What Is the Treatment for Blepharospasm?

The treatment of blepharospasm is highly easy and effective. Botulinum toxin injection into the affected muscle takes effect quickly. In many cases, one injection is sufficient.

Eye spasms may negatively affect a person’s daily life and may lead to important problems for eye health. If you have symptoms, you can consult an eye doctor and evaluate appropriate treatment options.

The treatment plan is determined according to the severity of symptoms, the frequency of spasms and accompanying eye or neurological problems. In some patients, treating underlying conditions such as dry eye, infection or irritation may also help reduce symptoms.
