Patients often come in about a drooping eyelid because of how it looks in photos. But ptosis is not only cosmetic. A lid that hangs low enough can block part of your vision, and in a young child it can affect how the eye develops.
What ptosis is
The American Academy of Ophthalmology (AAO) defines ptosis as a drooping of the upper eyelid. It can be slight, or severe enough to cover the pupil and block vision. Both children and adults can have it.
Ptosis in children
Children born with ptosis (congenital ptosis) usually have a problem with the levator, the muscle that lifts the eyelid. Signs include a droopy lid, uneven eyelid creases, and a child tipping the head back, lifting the chin or raising the eyebrows to see. The AAO warns that a lid that blocks vision can lead to amblyopia (“lazy eye”), and children with ptosis can also develop astigmatism or misaligned eyes.
Treatment depends on the child’s age, eyelid height, muscle strength and eye movements. Surgery may be recommended to improve vision, and any amblyopia must be treated too, with patching, glasses or drops. All children with ptosis need regular eye exams.
Ptosis in adults
In adults, ptosis (called acquired or involutional) usually happens when the levator muscle stretches or separates from the eyelid with age or after an injury. It can also follow some eye surgeries. Rarely, nerve or muscle diseases or tumors are the cause, which is why a complete exam comes first, sometimes with blood tests or imaging.
Treatment options for adults
- Surgery is the usual treatment. It is typically outpatient, with local anesthesia. Mild cases may need only a small adjustment of the lifting muscle; more severe ones may need the muscle shortened and reattached.
- Prescription drops. The AAO notes a daily drop, oxymetazoline, can lift the lid somewhat in some adults with acquired ptosis. It must be used every day to keep working and does not help ptosis from injury or nerve problems.
Before eyelid surgery
Tell your surgeon about every medicine and supplement you take, especially aspirin, blood thinners or any bleeding problem.
When a droopy lid is urgent
A lid that droops suddenly, especially with double vision, a headache, a large pupil or weakness elsewhere, needs emergency evaluation.
Some patients notice a droopy lid around the time of cataract surgery; this cataract surgery education site explains what to expect from that operation.
If a droopy eyelid is getting in the way of your vision or your child’s, an oculoplastic surgeon can tell you what is causing it and what can be done.
