Ptosis is a term used to describe excessive drooping of a person’s eyelid(s). This usually occurs due to weakness in the muscles elevating eyelid or due to an underlying injury to specific nerves or parts of the brain. Ptosis can lead to tearing and damaged vision. This condition can be diagnosed through a thorough physical examination. Treatment for the condition depends on the severity as well as the underlying condition. Eyelid lift surgery can fix the appearance of the lid, and in more severe cases surgery may also be needed to correct damaged vision. Some infants are born with ptosis, and in this case, or in the case of children that develop ptosis, surgery may need to be done to prevent them from having a lazy eye.
