What are the symptoms of a corneal abrasion?
A corneal abrasion is a scratch or scrape on the cornea, which is the clear, protective outer layer of the eye. Symptoms of a corneal abrasion can include:
- Pain: A corneal abrasion can cause moderate to severe pain, often described as a gritty or foreign body sensation in the eye.
- Redness: The eye may appear red or bloodshot due to irritation and inflammation.
- Tearing: Excessive tearing or watering of the eye can occur in response to the injury.
- Sensitivity to light: Photophobia, or sensitivity to light, is common with a corneal abrasion. Bright lights may be particularly bothersome.
- Blurry or decreased vision: Vision may be temporarily affected, especially if the abrasion is in the central part of the cornea.
- Foreign body sensation: It may feel like there is something in the eye, such as dirt or sand.
- Blepharospasm: Involuntary blinking or spasms of the eyelid may occur in response to the irritation.
If you suspect you have a corneal abrasion, it’s important to see an eye care professional for evaluation and treatment to prevent complications and promote healing.
What are the causes of a corneal abrasion?
Corneal abrasions can be caused by various factors, including:
- Foreign objects: Small particles such as dirt, dust, sand, or metal shavings can scratch the cornea if they come into contact with the eye.
- Contact lenses: Improper use, poor fit, or overuse of contact lenses can lead to corneal abrasions.
- Trauma: Direct trauma to the eye, such as a fingernail scratch, a poke from a tree branch, or a sports-related injury, can cause a corneal abrasion.
- Chemical exposure: Contact with chemicals, such as cleaning solutions, pesticides, or even hair dye, can cause chemical burns on the cornea, leading to an abrasion.
- Dry eye syndrome: Insufficient tear production or poor quality tears can lead to dry spots on the cornea, making it more susceptible to abrasions.
- Eyelid problems: Conditions that affect the eyelids, such as a drooping eyelid (ptosis) or an eyelid that turns inward (entropion), can cause the eyelashes to rub against the cornea, leading to abrasions.
- Corneal dystrophies: Certain inherited corneal disorders, such as map-dot-fingerprint dystrophy, can cause the surface of the cornea to become irregular and prone to abrasions.
- Eye surgery: Some eye surgeries, such as LASIK or cataract surgery, can lead to corneal abrasions as a complication of the procedure.
It’s important to seek prompt medical attention if you suspect you have a corneal abrasion, as untreated abrasions can lead to complications and potential vision loss.
What is the treatment for a corneal abrasion?
The treatment for a corneal abrasion depends on the severity of the injury. In general, treatment aims to relieve pain, prevent infection, and promote healing. Common treatments for corneal abrasions include:
- Topical antibiotics: To prevent infection, an ophthalmologist may prescribe antibiotic eye drops or ointment.
- Pain management: Over-the-counter pain relievers such as acetaminophen or ibuprofen may help reduce pain and inflammation. Your doctor may also prescribe pain medication if needed.
- Topical lubricants: Lubricating eye drops or ointments can help keep the eye moist and promote healing. They can also help reduce discomfort caused by dryness.
- Bandage contact lens: In some cases, a bandage contact lens may be placed over the cornea to protect it and promote healing. This is typically done in the doctor’s office.
- Follow-up visits: It’s important to follow up with your eye care professional as directed to monitor the healing process and ensure that no complications develop.
- Avoiding contact lenses: If a corneal abrasion is caused by contact lens use, it’s important to avoid wearing contact lenses until the eye has healed completely.
- Protective eyewear: To prevent further injury, you may be advised to wear protective eyewear, especially during activities that could result in eye injury.
Severe or deep corneal abrasions may require more intensive treatment, such as a bandage contact lens or surgery. It’s important to follow your doctor’s recommendations for treatment and attend all follow-up appointments to ensure proper healing.
