Ptosis

Ptosis occurs when the muscles that raise the eyelid aren't strong enough to do so properly anymore. 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 is hereditary in three main forms.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 (oculomotor nerve) which controls this muscle. Such damage could be a sign or symptom of an underlying disease such as a brain tumour and diseases which may cause weakness in muscles or nerve damage, such as Myasthenia Gravis.

Ptosis may require surgical correction if severe enough to interfere with vision or if cosmesis is a concern. Treatment depends on the type of ptosis and is usually performed by an ophthamolic plastic and reconstructive surgeon, specialising in diseases and problems of the eyelid.

Non-surgical modalities like the use of "crutch" glasses or special Scleral contact lenses to support the eyelid may also be used.

Ptosis that is caused by a disease will improve if the disease is treated successfully.
