Drooping Eyelid Symptoms

Drooping of one or both eyelids can be an irritating symptom, regardless of how long the patient has been experiencing it. Eyelid drooping can present upsetting changes to the appearance of the face and even interfere with vision if severe. In some cases, it is present from birth [1]. In other cases, it develops later in life, with a gradual or rapid onset depending on the cause.

Symptoms that can be associated with a drooping eyelid, depending on the cause, include:

  • Small pupil and lack of sweating
  • Enlarged pupil
  • Decreased ability to move the eye
  • Headache
  • Muscle weakness
  • Blurry vision
  • Eye pain, itching, or discharge

Drooping Eyelid Causes

Congenital Drooping Eyelid Causes:

Drooping of one or both eyelids can be present from birth and is called congenital ptosis [1]. Usually this is a benign condition with no identifiable cause, but occasionally it can be a sign of an underlying medical condition [2].

Neurological conditions:

  • Peripheral nerve damage: Injury to peripheral nerves that contribute to eyelid function can lead to drooping eyelid symptoms. This can occur via trauma to a major artery in the neck or compression by a tumor in the lung. There may be additional symptoms such as a constricted pupil and lack of sweating.
  • Decreased blood flow: Obstruction of blood supply in certain areas of the brain, such as during a stroke, can lead to drooping of one or both eyelids.
  • Structural abnormality in the brain: An aneurysm, meaning an enlarged portion of a blood vessel, can compress a major nerve that supplies the eye and eyelid (the oculomotor nerve). This causes eyelid drooping, decreased ability to move the eye, and an enlarged pupil. A similar process can occur due to a brain tumor.

Muscular conditions:

  • Neuromuscular condition: Communication between nerves and muscles can be disrupted by an inappropriate immune response. This results in muscle weakness, including in the muscles that hold up the eyelid.
  • Aging: The muscular structures that hold up the eyelid can gradually degenerate over time, leading to drooping eyelid symptoms.

Eye or eyelid conditions:

  • Infection: An infection of the eye socket can lead to eye pain, difficulty moving the eye, and a drooping eyelid.
  • Eyelid abnormality: A structural abnormality, such as a tumor or thickening caused by an allergic eye disease, can cause droopiness by weighing down the eyelid.

Underlying medical conditions:

  • Diabetes: As diabetes progresses, small blood vessels can be damaged, including ones that supply the oculomotor nerve. Disruption of the blood supply can cause a drooping eyelid along with decreased ability to move the eye [3].
  • Headache syndromes: Some headache syndromes can present with eyelid drooping as an additional symptom.
  • Thyroid disease: Abnormally high levels of thyroid hormone (hyperthyroidism or Grave's Disease) are more likely to cause pulled back eyelids than droopiness. However, in some cases, high thyroid hormone can cause the same neuromuscular disorder mentioned above, causing droopy eyelids [4].

5 Possible Conditions

The list below shows results from the use of our quiz by Buoy users who experienced drooping eyelid. This list does not constitute medical advice and may not accurately represent what you have.

  1. 1.Stroke or Tia (Transient Ischemic Attack)

    A stroke is a medical emergency. Strokes happen when blood flow to the brain is stopped.


    Top Symptoms:
    dizziness, leg numbness, arm numbness, new headache, stiff neck
    Symptoms that never occur with stroke or tia (transient ischemic attack):
    bilateral weakness
    Emergency medical service
  2. 2.Myasthenia Gravis (Over 50)

    Myasthenia Gravis is an autoimmune disease, where the immune system attacks the connection between nerves and muscles.


    Top Symptoms:
    weakness, general weakness, trouble swallowing, voice change, double vision

  3. 3.Carotid Artery Dissection

    A carotid artery dissection is the tearing of the walls of the carotid arteries, which deliver blood to the brain from the aorta. This is a medical emergency.

    About 10% have recurrence

    Top Symptoms:
    new headache, history of headaches, steady headache, neck pain on one side, headache near one temple
    Emergency medical service
  4. 4.Mitochondrial Myopathy

    Mitochondrial myopathy includes a group of inherited genetic disorders that affect the muscles of the body.


    Ultra rare
    Top Symptoms:
    fatigue, core symptoms of mitochondrial myopathy, muscle aches, unintentional weight loss, eye pain
    Symptoms that always occur with mitochondrial myopathy:
    core symptoms of mitochondrial myopathy
    Primary care doctor
  5. 5.Cluster Headache

    A cluster headache is a type of recurring headache that is moderate to severe in intensity. It is often one-sided head pain that may involve tearing of the eyes and a stuffy nose. Attacks can occur regularly for 1 week and up to 1 year. Each period of attacks (i.e. each cluster) is separated by pain-free periods that last at least 1 month or longer. Other common headaches may also occur during these cluster-free periods.

    Each attack can last from 15 min to 3 hours and occurs from once every other day up to 8 times per day. Cluster periods usually resolve in a few weeks to months but can last up to a year.

    Top Symptoms:
    severe headache, nausea, throbbing headache, history of headaches, sensitivity to light
    Symptoms that always occur with cluster headache:
    severe headache
    Hospital emergency room

Drooping Eyelid Treatments, Relief and Prevention

Seek emergency drooping eyelid treatment if:

  • You are having difficulty breathing. You may have a neuromuscular condition that is affecting the muscles controlling respiration.
  • You are experiencing neurological abnormalities such as confusion or slurred speech.
  • Your eyelid drooping started very suddenly.
  • You have decreased ability to move your eye or a constricted pupil and lack of sweating on the side of the drooping eyelid.
  • You have a severe headache along with the drooping eyelid.
  • You are experiencing eye pain and/or a fever.

In some cases, even though emergency treatment isn't necessary, you may need laboratory testing or radiology testing / imaging in order to make a diagnosis and select the best drooping eyelid treatment.

Make an appointment with your medical provider if:

  • Your eyelid drooping has worsened over time or is affecting your ability to see.
  • You have noticed muscle weakness in other parts of the body.
  • You have symptoms of high thyroid hormone such as weight loss or changes in your menstrual cycle.
  • You have noticed decreased peripheral vision.
  • You have previously been diagnosed with diabetes or a thyroid condition.

Your medical provider may prescribe one or more of the following treatments, depending on the cause of your drooping eyelid symptoms:

  • Medication to suppress abnormal immune system activation or improve communication at the neuromuscular junction.
  • Treatment for an underlying medical condition such as diabetes or increased thyroid hormone.
  • Referral to a surgeon [5].

Unfortunately, most causes of a drooping eyelid will not resolve without medical or surgical treatment.

  • If you have been diagnosed with an allergic disorder of the eyelid, avoiding allergens can help with drooping and discomfort.
  • Placing an icepack on the eye for a couple minutes can help improve eyelid drooping if a neuromuscular condition is the cause.

FAQs About Drooping Eyelid

Here are some frequently asked questions about drooping eyelid.

Why is my eyelid drooping suddenly?

Sudden eyelid drooping, or ptosis, can have a variety of causes. Peripheral nerves that travel through the neck can be disrupted, causing eyelid drooping along with a constricted pupil and lack of sweating (triad of Horner's syndrome) [6]. The eyelid drooping could also be caused by an abnormality in the brain such as bleeding or a stroke. You should seek medical evaluation as quickly as possible, especially if you are having other symptoms such as blurry vision or different sized pupils.

Why does one of my eyelids droop more than the other?

You may have one eyelid that has drooped more than the other ever since you were born. In this case, there is unlikely to be any underlying medical cause. If the drooping eyelid develops later in life, it may be caused by a process occurring only on that side. Possible conditions include a tumor on the eyelid, nerve injury, or an infection.

Can drooping eyelids cause vision problems?

Severely drooping eyelids (ptosis) can obscure your vision by blocking the eyes. In addition, eyelid drooping in early childhood can cause long-term visual problems due to the brain “favoring” the unobstructed eye. A child with a drooping eyelid should be regularly monitored, and the eyelid should be surgically corrected if visual problems in that eye begin to develop.

Can a drooping eyelid be a sign of a stroke?

Sudden eyelid drooping (ptosis) is a possible sign of a stroke [7]. Depending on the location of the stroke, one or both eyelids can be affected. If a stroke is the cause of eyelid drooping, other symptoms will often be present, such as one-sided weakness or blurry vision.
