What is blepharospasm?
Blepharospasm is involuntary blinking or twitching of your eyelid. The twitching is caused by a muscle spasm (involuntary muscle movement) around your eye. Blepharospasm is just one of several reasons your eyes might twitch. Other reasons include minor things, such as being tired. Serious reasons might include neurological diseases. Blepharospasm is a rare condition. It affects women more than men. It may run in families.
Symptoms of blepharospasm
Symptoms of blepharospasm include repeated, uncontrolled eye twitching or blinking. The twitching often happens during times you are overly tired, stressed, anxious, or when you are exposed to bright light and sunlight. The uncontrollable twitching can become worse over time. Eventually, you may feel as if it’s difficult to open your eyelids. As the condition progresses, your eyelids may be closed for several hours at a time. Spasms in your face can develop, as well.
What causes blepharospasm?
Blepharospasm is caused by abnormal brain function in the part of your brain that controls muscles. Symptoms can be triggered by something as minor as stress and being overly tired. Or it could be triggered by a neurological condition. Such conditions would include Tourette’s syndrome or Parkinson’s disease. Some medicines can make blepharospasm worse. Be sure to tell your doctor about any medicines you are taking.
How is blepharospasm diagnosed?
Your doctor will examine you and ask you about your symptoms. He or she will ask you about your medical history. If he or she suspects your eyelid twitching is caused by anything more than stress or being tired, your doctor may refer you to a specialist for a neurological exam. Such an exam might include imaging tests of your brain and eyes, such as X-ray, magnetic resonance imaging (MRI), or computed tomography (CT) scans. These scans allow doctors to look inside your body.
Can blepharospasm be prevented or avoided?
Blepharospasm cannot be prevented or avoided.
There are several treatments to ease your symptoms. Some injection-type medicines will treat muscle conditions by temporarily paralyzing them. The medicine is injected with a needle under the skin of the eyelid. There are some oral medicines available to treat blepharospasm symptoms. However, they don’t last long, and the symptoms return. A surgical procedure called a myectomy can treat symptoms. This surgery removes some of the muscles and nerves within the eyelid. Treatments also may depend on the underlying cause of your blepharospasm. For example, the medicine used to treat Parkinson’s disease may ease the eye twitch.
Living with blepharospasm
Blepharospasm is a lifelong disorder. Talk to your doctor about how to ease your symptoms. Also, consider keeping a journal to track when the twitching occurs. You may notice it happens during exposure to bright lights, times of stress, or when you are overly tired. Knowing your triggers can help you avoid or reduce your symptoms.
