A red, painful eye may seem like a minor irritation, especially after a long day, exposure to dust, or extended screen use. But when eye redness and pain occur together with blurred vision, excessive watering, light sensitivity, or discharge, the problem may be more serious.
A corneal ulcer is an open sore or wound on the cornea, the clear front surface of the eye. It is often associated with an infection and can become a medical emergency because untreated ulcers may damage the cornea and threaten vision.
Knowing the corneal ulcer symptoms and seeking prompt evaluation can make an important difference in protecting your eyesight.
What Is a Corneal Ulcer?
The cornea helps focus light into the eye while also providing a protective barrier. When this delicate tissue develops an open sore, it is called a corneal ulcer.
Corneal ulcers are commonly linked to infections caused by bacteria, viruses, fungi, or parasites. They may also develop after an eye injury or when an underlying condition damages the surface of the cornea.
Because the cornea plays an important role in clear vision, inflammation, infection, or scarring in this area should not be ignored.
Corneal Ulcer Symptoms You Should Know
Recognizing the symptoms of corneal ulcer early can encourage timely medical attention. Symptoms can vary depending on the cause and severity, but commonly include:
- Red or bloodshot eyes
- Eye pain or discomfort
- Excessive watering
- Increased sensitivity to light
- Blurred or reduced vision
- A feeling that something is stuck in the eye
- Eye discharge
- Swollen or irritated eyelids
- A white or gray spot appearing on the cornea
These are among the common signs of corneal ulcer reported by clinical sources. A visible white or gray spot may occur, although an ulcer is not always easy to see without an eye examination.
If painful symptoms are getting worse, particularly when accompanied by changes in vision or significant light sensitivity, it is important to seek eye care promptly.
What Causes a Corneal Ulcer?
Understanding the corneal ulcer causes can help reduce the risk of developing one.
1. Bacterial Infection
Bacteria are a common cause of infectious corneal ulcers. Contact lens wear can increase the risk, particularly when lenses are worn overnight, cleaned improperly, or exposed to non-sterile water. Bacterial keratitis may cause pain, redness, blurred vision, light sensitivity, watering, and discharge.
2. Viral Infections
Certain viruses, including herpes simplex and varicella-zoster virus, can affect the cornea and contribute to ulcer formation or keratitis.
3. Fungal Infections
Fungal infections may occur after certain eye injuries, particularly injuries involving plant material or soil. They can require specific treatment and professional diagnosis.
4. Parasitic Infections
Acanthamoeba is a parasite associated with serious corneal infections. Contact lens wearers are at particular risk when lenses are exposed to contaminated water or when proper lens-care practices are not followed.
5. Eye Injuries
A scratch, cut, burn, or other corneal injury can damage the protective surface of the eye and make it more vulnerable to infection. An injury that initially appears minor should therefore be monitored carefully if pain, redness, discharge, or vision changes develop.
6. Dry Eye and Other Eye Conditions
Severe dryness, problems with eyelid closure, previous eye surgery, certain corneal conditions, and some immune-related conditions may also increase vulnerability to corneal damage.
Who Is More At Risk?
Anyone can develop a corneal ulcer, but certain situations increase the risk.
Contact lens users need to be particularly careful. Sleeping in lenses, swimming while wearing lenses, poor cleaning practices, using water to rinse or store lenses, and failing to replace lenses or cases as recommended can increase the risk of serious corneal infection.
Other risk factors can include previous eye injuries, dry eyes, certain eye diseases, weakened immunity, previous eye surgery, and inappropriate use of steroid-containing eye drops.
Why Does a Corneal Ulcer Need Urgent Care?
A corneal ulcer is not simply another form of eye redness. It can progress and cause corneal scarring, changes in vision, or more severe complications if treatment is delayed. In serious cases, corneal damage can result in permanent vision loss.
This is why unusual corneal infection symptoms should not be treated as something to wait out at home.
Seek prompt evaluation if you experience:
- Significant or worsening eye pain
- Sudden or worsening blurred vision
- Strong sensitivity to light
- Persistent eye redness
- Excessive watering or discharge
- A visible white or gray spot on the cornea
- Symptoms after a contact-lens-related problem
- Eye symptoms following an injury
The CDC specifically advises contact lens users with symptoms such as pain, redness, blurred vision, light sensitivity, excessive tearing, or discharge to remove their lenses and contact an eye doctor immediately.
How Is a Corneal Ulcer Diagnosed?
An eye specialist will usually begin with a detailed examination of the eye. A slit-lamp examination allows the doctor to closely examine the cornea and identify signs of inflammation, injury, or an ulcer.
A fluorescein dye test may also help reveal damage to the corneal surface. Depending on the suspected cause, the doctor may collect a sample from the affected area for laboratory testing to identify an infection and guide treatment.
Accurate diagnosis matters because different infections require different approaches.
What Is the Treatment for a Corneal Ulcer?
Corneal ulcer treatment depends on its underlying cause, location, size, and severity.
For an infectious ulcer, a doctor may prescribe medication targeted toward the suspected organism. Bacterial infections may require antibiotic treatment, while fungal, viral, or parasitic infections require different medications. In some cases, laboratory testing helps determine the appropriate treatment.
More serious or non-healing ulcers may require additional treatment or procedures. In severe cases, surgical treatment, including corneal transplantation, may be considered.
Because treatment depends on the cause, using leftover eye drops or self-medicating is not a substitute for a professional eye examination.
Can You Prevent a Corneal Ulcer?
Not every corneal ulcer can be prevented, but several habits can lower your risk.
If you wear contact lenses:
- Wash and dry your hands before handling lenses.
- Follow the recommended cleaning and replacement schedule.
- Never sleep in lenses unless specifically advised by your eye-care professional.
- Do not swim while wearing contact lenses.
- Never rinse or store contact lenses in tap water.
- Use appropriate sterile contact-lens solutions.
- Replace your contact lens case as recommended.
- Do not share contact lenses.
Eye protection during activities that could cause injury can also help protect the cornea.
Don’t Ignore a Painful Eye Ulcer
A painful eye ulcer, persistent redness, or sudden vision changes deserve attention. Many common eye conditions can cause similar symptoms, so it is not always possible to determine the cause simply by looking at the eye or waiting for symptoms to improve.
Early professional evaluation can help identify whether the problem is an infection, injury, inflammation, or another condition and determine the appropriate treatment.
If you are experiencing corneal ulcer symptoms, particularly pain, redness, light sensitivity, discharge, or changes in vision, arrange an eye examination without unnecessary delay.
