Famous people with Ptosis

Ptosis has many names, it is usually known as "lazy eye", "droppy eye" and so on. It must not be mistaken with amblyopia, which is also called lazy eye, which is a disorder of the visual system in the brain.

It may be classified as acquired (Usually in Older people) and congenital (in children). It can also be classified by the cause of the Ptosis.

There are two muscles that are involved in the elevation of the upper eyelid the levator palpebrae superioris and the Mueller muscle.

Causes can be.

1. Myogenic; This is when there is a problem with the muscles of the upper eyelid. This may be congenital or due to other diseases such as Myasthernia gravis.
2. Aponeurotic; Which may be post-operative.
3. Neurogenic; Problems, with the nerves that supply the muscles that open the eye lid
   
4. Mechanical; This is when the dropping is caused by either swelling of the upper lid or by tumors
5. Pseudoptotic.; This is due to lack of support due to a small eye ball, or lack of the eye ball.

In children it is caused usually by myogenic dysgenesis (poor muscle development), but other cause such as birth trauma must also be ruled out

The treatment depends on the cause. For adults who do not want to undergo surgery, there are special glasses with a crutch attached that can be used to lift the lid.

The main treatment is surgery. There are many techniques and methods, all depending on the cause of the ptosis and the age of the patient and ultimately the surgeons preference.

If you need more information you should see you ophthalmologist. This is very important for children with ptosis because they may have other conditions which have to be addressed, such a neurological disorders, amblyopia and others.

Others include Thom Yorke of Radiohead, and Lenny Kravitz.
