Ptosis (say "TOH-sus") means the upper eyelid droops over the eye. Some people are born with ptosis. Others may get it later in life. It may be caused by problems with the muscles or nerves that move the eyelid.
When you have ptosis, the drooping eyelid may block your vision. This can make it very hard to do your daily activities. Some people also have headaches or fatigue.
Your doctor will ask questions about your symptoms and do an examination. They'll take measurements of the eyelid and test the strength of the muscles. If the doctor thinks there is a problem with the muscles or nerves, you may have more tests. These may include imaging tests, such as an MRI.
Treatment for ptosis depends on the cause. Your doctor will try to find the cause and see if treatment may help. Some causes of ptosis may go away on their own over time. If ptosis interferes with your vision, your doctor may talk to you about having surgery.
