What causes congenital ptosis?
Ptosis occurs in children if excessive tension in the levator palpebrae superioris or occipito-third fibrous tissue causes a tractional ptosis. In contrast, infantile blepharospasm occurs in children because of a lack of neural connections in the ocular muscles leading to an abnormal reflex contraction of the eyelids. The primary cause of blepharospasm in older children and adults is usually unknown.
What does it mean when your left eye is jumping?
