Usually ptosis can be cured. The causes of ptosis are divided into two main types: congenital and acquired factors, and depending on the cause of ptosis, different treatments should be adopted. Currently, ptosis is mostly due to congenital factors and requires prompt surgical treatment. Congenital ptosis is mainly improved with epicanthoplasty, which exposes the visual axis and also promotes normal development of vision. However, this surgery carries certain risks and may result in complete loss of eye muscle function or, in severe cases, incomplete eyelid closure if the surgery is not ideal. In addition, some patients have regression after surgery, and if symptoms worsen, a second surgery is required if necessary; most patients can be cured after surgery. In contrast, upper eyelid ptosis due to acquired factors is most often the result of complications from other diseases and should first be treated for the primary cause, which can be restored to normal in most patients after the primary cause is controlled. Most ptosis is treated surgically, such as epiglottis shortening, which is suitable for unilateral or bilateral mild to moderate congenital ptosis and the levator muscle is still partially functional. It is important to take care of the postoperative period and change the medication on time so as not to cause infection.
