Blepharoptosis or ptosis (pronounced TOE-sis) is defined as drooping of the upper eyelid. Ptosis can be bilateral or unilateral and can be difficult to identify unless a proper exam is performed.
An eyelid twitch, or blepharospasm, is a repetitive, involuntary spasm of the eyelid muscles. A twitch usually occurs in the upper lid, but it can occur in both the upper and lower lids. For most people, these spasms are very mild and feel like a gentle tug on the eyelid. Others may experience a spasm strong enough that it forces you to close your eyelid completely. Some people never have any noticeable signs.
