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.
Difficulty reading and driving are common complaints. Raising the entire brow with the muscles of the forehead and scalp may cause headaches and eyestrain as well. Treatment is surgical and there are a number of possible approaches. The goal is to elevate the lid to match the other side with a minimum of scars and side effects. This creates a dry eye situation that may be difficult to manage.
