Can ptosis in childhood cause other problems with a child’s eyes if untreated?

Yes. Ptosis can lead to other vision problems, including astigmatism, or an irregularly shaped cornea, or amblyopia, also commonly called lazy eye. It is important when you take a child to the doctor for a routine well-child visit that the doctor screen or test his or her vision to detect vision abnormalities such as ptosis or vision abnormalities that develop as a result of ptosis.
