PTOSIS is a drooping of the upper eyelid. It can block normal vision. Ptosis can be present in children or adults.
The most obvious sign of ptosis is the drooping lid itself. Ptosis can affect one or both eyelids. It may be present at birth (congenital) or occur later in life.
Surgery can treat ptosis by tightening the levator, or eyelid-lifting muscle. In severe ptosis, when the levator muscle is extremely weak, the lid can be attached to or suspended from under the eyebrow so that the forehead muscles can do the lifting.
Immediately after surgery, it may be difficult to completely close the eye, but this is only temporary. Lubricant eyedrops and ointment are helpful during this period.
Although surgery usually improves the height of the lid, both eyelids may still not appear perfectly symmetrical. In some cases, more than one operation may be required. In rare cases, full eyelid movement does not return. If amblyopia, or lazy eye, is present, treatment with patching, eyeglasses, or eyedrops may also be necessary.
