Dropping of the lid is known as ptosis. It can be corrected surgically with different procedures after detailed ophthalmic and systemic evaluation. It is the name given to the abnormally low position of the upper eyelid, which can prevent the eye from seeing as well as it should; often resulting in a lazy eye or amblyopia. The reason that it has occurred is due to a weakness in the muscle that lifts the upper lid eye called the levator palpebrae.
