Blepharospasm

Overview

Blepharospasm is a condition where the muscles around your eyes squeeze or twitch without you wanting them to. This can cause your eyelids to blink a lot or even close tightly, making it hard to see.

Blepharospasm is not very common. It affects about 5 to 10 people in every 100,000. It is the most common type of a group of movement problems called focal dystonias.

It most often starts in middle age, usually between 40 and 60 years old. Women are more likely to get it than men.

Symptoms

Common symptoms

• Frequent blinking that you cannot control.
• Eyes feeling dry, gritty, or irritated.
• Sensitivity to light (photophobia).
• Eyelids that close on their own, sometimes for a few seconds or longer.
• Trouble keeping your eyes open, especially when reading or concentrating.

Symptoms in children

• Blepharospasm is very rare in children. If it happens, the main sign is fast blinking or squinting that doesn't stop.

Symptoms in older adults

• In older adults, the eyelid closing can be stronger and last longer.
• This may make it hard to see while walking, increasing the risk of falls.

Causes

Main causes

• The exact cause of blepharospasm is unknown. It is thought to be a problem with a part of the brain that controls muscle movements, called the basal ganglia.
• Sometimes it happens on its own (primary blepharospasm).
• Other times it can be triggered by another health problem, like very dry eyes, certain medicines, or a brain injury (secondary blepharospasm).

Risk factors

• Family history – if a close relative has blepharospasm or other dystonias.
• Being a woman in middle age.
• Having other conditions that affect the eyes or brain.

When to see a doctor

See a doctor urgently if:

• You have sudden, severe eye pain or vision changes.
• Your eyelid closes completely and you cannot open it at all.

Book a routine appointment if:

• Your blinking or eyelid closing bothers you and interferes with daily life.
• The twitching lasts for more than a few weeks without getting better.
• You want to know what is causing your symptoms.

Diagnosis

A doctor, often an eye specialist (ophthalmologist) or a nerve specialist (neurologist), will ask about your symptoms and examine your eyes and face. They may watch you blink and try to hold your eyes open to see how your eyelids respond.

Tests that may be done

• There is no specific test for blepharospasm. The diagnosis is based on your history and exam.
• Sometimes blood tests or brain scans are done to rule out other causes.

What to expect at your appointment

The doctor will likely ask you to blink, squint, and try to keep your eyes open while they gently try to open them. This helps them understand how severe the spasm is. They will also check your vision and eye health.

Treatment

Treatment for blepharospasm can help control symptoms and improve your quality of life. The goal is to make it easier to keep your eyes open and see clearly. Options range from simple self-care to medical treatments and, in rare cases, surgery.

Self-care at home

• Wear sunglasses or tinted glasses to reduce light sensitivity.
• Use lubricating eye drops (artificial tears) to keep eyes moist.
• Avoid caffeine, alcohol, and other triggers that may make spasms worse.
• Practice relaxation techniques like deep breathing to manage stress.
• Get enough sleep and rest your eyes during the day.

Medical treatments

The most effective treatment is periodic injections of botulinum toxin into the muscles around the eyes. This protein helps relax the muscles and reduce spasms for several months. Oral medications may also be tried, but they often have side effects and are less effective. Always discuss the best option with your healthcare provider.

When is surgery considered?

If injections do not work well, a surgery called myectomy may be considered. In this procedure, some of the eyelid muscles are removed to stop the spasms. Surgery is used only for severe cases that do not respond to other treatments.

Living with this condition

Living with blepharospasm can be challenging, but many people manage well with treatment. You may need to adapt some activities, like taking breaks when reading or using a cane for balance if your vision is affected temporarily.

Lifestyle tips

• Manage stress through yoga, meditation, or hobbies.
• Wear protective eyewear in bright or windy conditions.
• Tell family and friends about your condition so they can support you.
• If symptoms make driving hard, talk to your doctor about when it is safe to drive.

Diet and exercise

A balanced diet and regular exercise can help your overall health. Some people find that reducing caffeine or alcohol helps lessen symptoms. No specific diet is proven to treat blepharospasm.

Mental health and emotional wellbeing

Blepharospasm can cause anxiety, embarrassment, or frustration because you cannot control your eyelids. It may also affect your social life and work. If you feel overwhelmed, talk to a mental health professional. If you have thoughts of harming yourself, call your local crisis support line immediately.

Prevention

There is no known way to prevent blepharospasm since the cause is not fully understood. Avoiding known triggers like stress and eye strain may help reduce how often spasms happen.

Complications

If left untreated

• Difficulty seeing clearly because the eyelids close often, which can interfere with driving, reading, and walking.
• Increased risk of falls or accidents.
• Social withdrawal or depression due to embarrassment about the symptoms.

Long-term outlook

With proper treatment, most people with blepharospasm get significant relief from their symptoms. It is not a life-threatening condition, and many people continue to lead active, full lives. Treatment usually needs to be repeated, but symptoms often become easier to manage over time.
