Under normal circumstances, the eyelid opens and shuts by the contraction of an eyelid muscle (the levator muscle). This muscle is inserted in a cartilaginous position just above the eye lashes.
When this muscle detaches from its attachment point (with age for example, or after previous eye operations), the eyelid droops.
It is also possible that the muscle itself does not work properly (for example after paralysis or muscle pathology) which causes the eyelid to weaken.
The eyelid droops or weakens.
Ptosis of the upper eyelid generally affects old people.
The main cause is age.
When the muscle not longer works properly after paralysis or a muscle pathology) spontaneous healing is possible.
Ptosis of the upper eyelid is diagnosed by a clinical examination by an ophthalmologist.
There is no treatment for preventing ptosis of the upper eyelid.
