Texas Ptosis Ptosis is the medical term for a noticeable droopiness of the upper lid. AGE - This is the most common cause of ptosis. The muscles that elevate the eye stretch and became thinned as we age, resulting in a loss of muscle tone and an inability to raise the upper lid well.
Ptosis affects both eyes, but often one eye appears worse than the other.
Eye surgery, such as cataract removal, may aggravate this condition. Three-quarters of the time it affects only one eye. Lacerations, burns and chemical injuries may also cause this droopiness. These are rare but must be diagnosed properly to avoid unnecessary surgery until the timing is right. Symptoms are functional as well as cosmetic.
