【Causes・Disease】

Posis is abnormally low positioned one or both upper eyelid, which can cause the defect in vision or bad appearance.
The causes of ptosis are congenital and acquired.
For congenital ptosis cases, ptosis can be recognized soon after the birth. It is said that one side ptosis is accounted for a big portion. Since patient can only see below, in order to get normal vision, patients will raise their chins to see.
The most cause of acquired ptosis is aging. With the increase of age, eyelid muscles and tissues gradually weaken, which may cause ptosis. Besides aging, trauma and nerve paralysis can also cause ptosis. Recently, ptosis caused by contact lenses (especially hard contact lenses) is also not rare.

【Symptoms】

The main symptom of ptosis is the drooping of the upper eyelid, which may cause the narrowing of vision.
In addition, because the muscles around eyes need extra strength to lift eyelid, patients may feel fatigue.
The degree of symptoms varies from person to person, the symptoms also develop differently if the cause is different.

【Treatment】

The treatment of congenital ptosis is basically surgery. Because surgery is available as long as the child is more than 6 months old, it is not necessary to undergo surgery with panic. However, when the power of eyesight is very strong, and it affects the development of vision, it is recommended to go to the ophthalmology clinic to check the necessity and time of surgery according to the visual function evaluation and complications.
The treatment of acquired ptosis is also surgery. Ptosis (aging and contact lens) with relatively good eyelid muscle function is expected to recover. For other acquired ptosis, according to the conditions of the eyelid muscle function caused by different diseases, surgical methods are different, the treatment effect is limited.
Besides surgery, there are botulinum toxin injections. For mild ptosis, botulinum toxin injection may be a common treatment. Botox can temporarily paralyze eyelid muscles, and the muscles to lift eyelid are easier to work. This treatment usually lasts for several months and requires repeated operation.

【Summary】

If ptosis develops, it interferes with visual field, which will cause inconvenience in daily life. The choice of treatment is determined by factors such as the power, causes and age. Consulting a professional ophthalmologist to evaluate symptoms and decide proper treatment is very important.
