What is a drooping eyelid (ptosis)?
Ptosis is when the upper lid margin drops toward the pupil because the muscle or tendon that lifts the lid has weakened. It is different from excess skin, and is treated by surgery on the lifting muscle.
Difference from excess skin
With excess skin the lid margin is in place and the skin above it hangs. With ptosis the margin itself is low. Removing skin alone does not correct ptosis.
Causes
- Age-related tendon loosening (most common)
- Many years of hard contact lens wear
- Congenital muscle differences
- Nerve and muscle conditions
When is it urgent?
A lid that droops suddenly, especially with double vision, headache or an enlarged pupil, needs urgent assessment.

Frequently asked questions
Is ptosis surgery the same as blepharoplasty?
No. Blepharoplasty removes excess skin; ptosis surgery tightens the muscle that lifts the lid. Both can be done together if needed.
