Experiencing pain in the corner of your eye can be unsettling and uncomfortable. This specific location of eye pain can sometimes point to particular underlying issues. While some causes are minor and easily addressed with home care, others may require medical attention to prevent complications. Understanding the potential reasons behind pain in the corner of your eye is crucial for timely and effective management.
Pain in this area can manifest in various ways, such as burning, sharp, or aching sensations. Accompanying symptoms, like light sensitivity, redness, discharge, or vision changes, can offer valuable clues to the cause. For instance, pain concentrated in the inner corner might suggest problems with your tear ducts, whereas discomfort in the outer corner could relate to issues affecting the eyelids or surrounding structures.
It’s important to note that pain in the corner of your eye can be related to conditions directly affecting the eye itself, or it might be a symptom of a broader health issue. This article will explore common and less common reasons for corner of eye pain, helping you discern when self-care measures are appropriate and when professional medical advice is necessary.

Common Causes of Pain in the Corner of Your Eye
Several common conditions can lead to discomfort specifically in the corner of your eye. These often involve structures located in or around this area, such as the eyelids, tear ducts, and conjunctiva.
Stye
A stye is a common culprit for pain in the corner of the eye, particularly if it’s localized to the eyelid margin. This is a painful, red bump that develops on the eyelid, often at the base of an eyelash. Styes are usually caused by a bacterial infection of the oil glands in the eyelid. The pain from a stye is often described as sharp or throbbing and can be more pronounced when blinking or touching the area. Because styes occur on the eyelid, they can easily affect the corners of the eye, causing localized pain there.
Blepharitis
Blepharitis is an inflammation of the eyelids, commonly affecting the edges where eyelashes grow. This condition can cause redness, itching, and a gritty or burning sensation in the eyes. Blepharitis can affect the entire eyelid margin, including the corners of the eyes. The inflammation in the corners can lead to pain or discomfort felt specifically in these areas.
Tear Duct Infection (Dacryocystitis)
The inner corner of the eye is where tear ducts are located, responsible for draining tears away from the eye. An infection of the tear duct, known as dacryocystitis, can cause pain, redness, and swelling in the inner corner of the eye. This condition often occurs when the tear duct becomes blocked, leading to a buildup of bacteria. Pain associated with tear duct infections is typically localized to the inner corner and may be accompanied by excessive tearing and discharge.
Dry Eye Syndrome
Dry eye syndrome occurs when your eyes don’t produce enough tears or the tears are of poor quality. While dry eye can cause a general gritty or burning sensation across the entire eye surface, the corners can sometimes be particularly sensitive. The dryness can irritate the delicate tissues in the corners of the eye, leading to pain or discomfort felt in these specific locations.
Conjunctivitis (Pink Eye)
Conjunctivitis, or pink eye, is an inflammation of the conjunctiva, the clear membrane covering the white part of the eye and the inner surface of the eyelids. Conjunctivitis can be caused by viral or bacterial infections, allergies, or irritants. Inflammation from conjunctivitis can affect all parts of the conjunctiva, including the corners of the eye, leading to pain, itching, redness, and discharge that may be felt or seen accumulating in the corners.
Corneal Abrasion
A corneal abrasion is a scratch on the cornea, the clear front surface of the eye. While corneal abrasions can cause pain across the entire eye, the sensation can sometimes be perceived as being more intense or localized in certain areas, including the corners, depending on the location and extent of the scratch. Sharp pain, feeling like something is in your eye, and increased sensitivity to light are common symptoms.
Uveitis
Uveitis is inflammation of the uvea, the middle layer of the eye. Anterior uveitis, affecting the front part of the uvea, can cause pain in the eye. While uveitis pain is often felt throughout the eye, inflammation and pressure changes within the eye could potentially be perceived as more prominent in certain areas, including the corners, depending on the specific pattern of inflammation. Uveitis typically causes deep aching pain, redness, light sensitivity, and blurred vision.
Less Common but Serious Causes of Eye Pain
While the conditions listed above are more frequent causes of corner of eye pain, some less common but more serious conditions can also manifest with eye pain, sometimes including pain in the corner of the eye.
Sinus Infection (Sinusitis)
Sinus infections can sometimes cause eye pain due to the proximity of the sinuses to the eyes. The sinuses are air-filled cavities around the nose and eyes. Inflammation and pressure buildup in the sinuses, especially the sinuses located near the eyes, can radiate pain to the eye area, including the corners. This pain is often described as a dull ache or pressure around the eyes and face.
Headaches and Migraines
Certain types of headaches, particularly migraines and cluster headaches, can cause pain around the eyes, which may be felt in the corners. Migraines can cause intense throbbing pain, light sensitivity, and nausea. Cluster headaches are known for severe, piercing pain that is often concentrated around one eye and can radiate to the corner of the eye.
Glaucoma
Acute angle-closure glaucoma is a serious condition involving a sudden increase in pressure inside the eye. This can cause severe eye pain, which may be felt throughout the eye or in specific areas. While glaucoma pain isn’t always localized to the corner, the intense pressure and pain associated with acute glaucoma could be experienced in various parts of the eye. Acute glaucoma is a medical emergency and requires immediate treatment to prevent vision loss.
Optic Neuritis
Optic neuritis is inflammation of the optic nerve, which transmits visual information from the eye to the brain. Inflammation of the optic nerve can cause eye pain that is often worsened by eye movement. While the pain is generally felt behind the eye, it can sometimes be perceived as originating from or radiating to different parts of the eye, including the corners. Optic neuritis can also cause vision changes, such as blurred vision or decreased color vision.
Stroke
In rare cases, sudden and severe eye pain, especially when accompanied by other neurological symptoms, could be a sign of a stroke. While eye pain is not a primary symptom of stroke, stroke can affect various neurological pathways and might, in some presentations, include eye pain. If you experience sudden, severe eye pain along with symptoms like sudden headache, weakness, numbness, difficulty speaking, or vision changes, seek immediate medical attention as it could be a sign of stroke.
When to Worry and Seek Medical Attention
While some instances of corner of eye pain can be managed with home remedies, it’s crucial to recognize when your symptoms warrant medical evaluation. Seek prompt medical attention if you experience any of the following:
- Severe or sudden eye pain: Intense pain that comes on suddenly should be evaluated by a healthcare professional.
- Eye pain accompanied by vision changes: Blurred vision, vision loss, double vision, or halos around lights are concerning symptoms.
- Eye injury or trauma: If your eye pain is the result of an injury, seek medical attention to rule out serious damage.
- Persistent eye pain: Pain that lasts for more than a couple of hours or recurs frequently needs medical assessment.
- Redness, swelling, or discharge from the eye: These signs can indicate an infection that requires treatment.
- Sensitivity to light: Increased light sensitivity along with eye pain can be a symptom of various eye conditions.
- Headache, nausea, or vomiting with eye pain: These accompanying symptoms can suggest more serious underlying issues like glaucoma or migraines.
How to Relieve Corner of Eye Pain
Treatment for pain in the corner of your eye depends entirely on the underlying cause. Some conditions can be managed with home care, while others require prescription medications or medical procedures.
- Warm Compress: For conditions like styes, blepharitis, and tear duct infections, applying a warm compress to the corner of your eye for 10-15 minutes, several times a day, can help soothe pain and promote healing.
- Artificial Tears: For dry eye syndrome, over-the-counter artificial tears can provide lubrication and relief.
- Prescription Eye Drops or Ointments: Bacterial infections like conjunctivitis, styes, or tear duct infections may require antibiotic eye drops or ointments prescribed by a doctor. Steroid eye drops may be used for inflammatory conditions like uveitis or scleritis, under medical supervision.
- Oral Medications: Conditions like sinus infections, severe blepharitis, or orbital cellulitis might necessitate oral antibiotics or other medications prescribed by a healthcare provider.
- Pain Relievers: Over-the-counter pain relievers like acetaminophen or ibuprofen can help manage pain associated with headaches, sinus infections, or minor eye irritations, while awaiting specific treatment for the underlying cause.
It is important to avoid self-treating eye pain, especially if it is severe or accompanied by concerning symptoms. Always consult with a healthcare professional for proper diagnosis and management.
Self-Care Strategies for Eye Health
Maintaining good eye hygiene and adopting healthy habits can help prevent some conditions that lead to eye pain, including pain in the corner of your eye.
- Practice good hygiene: Wash your hands thoroughly before touching your eyes or handling contact lenses.
- Proper contact lens care: Clean, disinfect, and replace contact lenses as directed by your eye care professional.
