Ptosis is an abnormally low position (drooping) of the upper
eyelid. The drooping may be worse after being awake longer, when the individual's muscles are tired. This condition is sometimes incorrectly referred to as a "lazy eye", a separate condition known as
Amblyopia. If severe enough and left untreated, the drooping eyelid can
cause other conditions, like
Amblyopia or
Astigmatism. This is why it is especially important for this disorder to be treated in children at a young age, before it can interfere with vision development.
Ptosis occurs when the
muscles that raise the eyelid (
levator and
Müller's muscles) are not strong enough to do so properly. It can affect one eye or both eyes and is more common in the elderly, as muscles in the eyelids may begin to deteriorate. One can, however, be born with ptosis, congenital ptosis. Congenital ptosis is not hereditary. Causes of congenital ptosis remain unknown. Ptosis may be caused by damage/trauma to the muscle which raises the eyelid, or damage to the
nerve (3rd cranial nerve (oculomotor nerve)) which controls this muscle. Such damage could be a sign or symptom of an underlying
disease such as
diabetes mellitus, a
brain tumor, and diseases which may cause weakness in muscles or nerve damage, such as
myasthenia gravis.
