Ptosis is the medical term for a condition in which the upper eyelid droops down slightly or in severe cases, the lid droops low enough to cover the whole pupil and block normal vision. Ptosis can occur in both children and adults.
A number of factors may contribute to the development of ptosis. These include:
- Weakening of the levator muscles (muscles of the upper eye lid) from ageing or may be present at birth
- Brain and spinal cord injuries resulting in weakening of facial and eye muscles
- Auto-immune diseases such as Myasthenia gravis
- Cluster headaches
If you have ptosis, there would be a visible drooping of the upper eyelid, giving the eye a smaller than usual appearance. You may also unconsciously raise your eyebrows and tilt your head frequently to have a better view of objects.
Treatment methodology of ptosis in adults and children varies depending on the cause.
