Blepharospasm is a muscle disorder that causes involuntary spasms of the muscles around your eye. These spasms can result in uncontrolled narrowing or closing of your eyelid. This could impair your vision, and make everyday tasks such as driving or using a computer difficult.
If you experience any of these symptoms, you could have blepharospasm:
Dry eyes or watering eyes
Your doctor will diagnose blepharospasm based on your symptoms. As blepharospasm progresses, blinking usually becomes more frequent, forceful, and uncontrollable. Bright lights, noise, stress, polluted air, or wind can make your symptoms worse. Without treatment, you will probably not experience an improvement in your condition.
To help treat blepharospasm, BOTOX® is injected directly into the affected muscles. The neurotoxin relieves the muscle spasm and its symptoms. Injection needles are fine, and the process does not take a long time. You may experience pain, tenderness, and bruising at the injection sites. A BOTOX® neurotoxin injection will reduce the muscle spasms around the eye. You may see results in just a few days. You should be able to fully open your eyes and resume normal daily activities.
