Ptosis may be due to congenital hypoplasia of the nerves in the upper part of the eyelid, or it may be caused by eye diseases. Parents should take their babies to the hospital to find out the exact cause of ptosis and get targeted treatment. 1. Congenital hypoplasia of the upper eyelid nerves: Surgery is the main treatment for babies with ptosis due to congenital causes. Depending on the severity of the ptosis, surgery such as levator palpebral muscle folding, levator palpebral muscle shortening, frontalis muscle flap suspension, etc. can be performed. 2. Eye diseases: Ptosis can also be caused by eye diseases such as ophthalmospasm, ocular myasthenia gravis, and functional ptosis. For ptosis caused by diseases, the specific cause should be found out and the existing diseases of the eye should be treated. If your baby has a droopy upper eyelid, it is recommended that you seek prompt medical attention to identify the cause of the condition. During the treatment, you should pay attention to your baby’s eye care, observe the eye condition more often, maintain eye hygiene, and don’t let your baby rub his eyes with his hands to avoid symptoms of infection.
