Eyelid ptosis is a lowering of the upper-eyelid margin. It may affect one or both eyes and vary in severity.

It is not simply excess skin. In ptosis, the eyelid margin itself sits lower than normal.

When the eyelid may interfere with vision

When marked, the eyelid may cover part of the pupil and restrict the upper visual field. Some people compensate by raising their eyebrows, contracting the forehead or tilting their head.

Possible signs

one eyelid sitting lower than the other;
difficulty keeping the eyes open;
a feeling of heaviness or fatigue;
frequent use of the forehead muscles;
reduction of the upper visual field.

Ptosis or dermatochalasis?

In ptosis, the eyelid margin is lower. In dermatochalasis, excess skin folds over the eyelid. The two conditions may occur together and require separate assessment.

Causes and assessment

Ptosis may be congenital or acquired and can have different causes, including changes in the levator muscle, its aponeurosis, the nerves or other structures. The consultation considers onset, variability, muscle function, symmetry and any possible impact on vision.

Treatment depends on the cause and individual characteristics. A procedure cannot be selected appropriately without measurements and specialist examination.

Sudden ptosis must not be ignored

A suddenly drooping eyelid—particularly with double vision, unequal pupils, eye or neck pain, severe headache, weakness, or difficulty speaking or swallowing—requires immediate medical attention.

Frequently asked questions

Is ptosis always age-related?

No. It may be present from birth or develop later for different reasons.

Can it affect vision?

If the eyelid margin covers part of the pupil, it may restrict the upper visual field.

Can it affect just one eye?

Yes. Ptosis may be unilateral or bilateral.

Can it be diagnosed from a selfie?

No. Eyelid measurements, movement assessment and an eye examination are required.
