Ptosis is when the upper eyelid sits lower than normal. It may affect one or both eyes and can range from barely noticeable to covering the pupil.
Causes
- Age. The muscle tendon that lifts the eyelid stretches over time. This is the most common cause.
- Congenital. Some children are born with a weak lifting muscle.
- Long-term contact lens wear or previous eye surgery
- Nerve or muscle conditions, which are less common
Go to an emergency department if an eyelid droops suddenly, especially with double vision, a severe headache, a large pupil or weakness elsewhere in the body.
Why it matters
- It can block the upper field of vision, making reading and driving harder
- People often raise their eyebrows to compensate, causing headaches
- In children, it can cause lazy eye if it covers the pupil
Treatment
Ptosis surgery tightens or shortens the lifting muscle, usually as a day procedure under local anaesthesia. Your doctor will first look for any underlying cause. See our eyelid and oculoplasty care.
