Question: Which muscles open and close the eyelid?

Answer: The orbicularis muscle closes the eye and is innervated by CN7. The levator palpebrae opens the eye and is innervated by CN3.

Didi, the possibilities here are:

1. Eyelid Fasciculations – harmless twitching
2. Blepharospasm – usually both eyes, may need botox, harmless
3. Hemifacial Spasm – involves half of face, potentially dangerous.

I don’t know why sugar levels are being checked, unless there is some kind of nerve palsy going on as well. These are all questions best asked of the eye doctor who has seen your husband.

Ps.. I got a second opinion and was told my muscle may need to be tightened. As I mentioned, both eyes opened fine before surgery; even with the hooding, it’s obvious in pics.
