Ptosis, which is commonly referred to as drooping eyelid, is nearly always the result of weakened muscles in the eyelid. It can be caused by genetic factors, or a result of an injury, mass affect or can be a simple isolated problem in children.
The most common symptom is an eyelid that physically droops. Children who have drooping eyelids may have associated refractive error and need glasses. A droopy eyelid may also cause amblyopia also known as lazy eye.
The most common cause of drooping eyelids is muscle weakness. This weakness may be congenital, or may be the result of a disease of the eyes. Neurological disorders can also contribute to drooping eyelids. It’s important to see an eye doctor to rule out more serious causes.
Depending on the age of the child and the severity of the drooping eyelids, medical or surgical correction maybe recommended.
