Symptoms of blepharospasm
Symptoms of blepharospasm include uncontrollable eye twitching or blinking.
When you’re exhausted, agitated, or anxious, you’re more likely to twitch. It can also occur when you’re exposed to strong light and sunlight. However, it can improve when you’re asleep or concentrating on a task.
The uncontrollable twitching can become worse over time. You may eventually find it difficult to open your eyelids. Your eyelids may close for several hours at a time as the problem worsens. The muscles of your face may also spasm.

While there is no cure for blepharospasm, there are treatments to ease your symptoms.
- Injectable medications, such as botulinum toxin, better known as Botox, can treat muscle conditions. The medicine is injected with a needle under the skin of the eyelid to temporarily weaken the muscles in the eyelids.
- Oral medicines may work, but only for a short period of time as symptoms usually return.
- Surgical procedure called a myectomy. It removes some of the muscles and nerves within the eyelid.
