Your eyes are among the most sensitive parts of your body, and even minor injuries or infections can result in severe complications. One of these conditions that can be frightening and painful is a corneal ulcer. If you have ever had redness, blurred vision, or eye pain that persists, you should know what a corneal ulcer is, how it can impact your eye, and what you can do for treatment and prevention.
What Is a Corneal Ulcer?
A corneal ulcer is an open eye sore on the cornea, the transparent, dome-shaped tissue that covers the front of the eye. The cornea does much of the work of focusing your vision. When it is injured, your eyesight can be greatly impaired. This is usually caused by infection, but it can be the result of injury, dry eyes, or overuse of contact lenses. It’s not just uncomfortable—it can cause loss of vision if left untreated.What Causes a Corneal Ulcer?
There are a number of potential causes of corneal ulcers, such as:- Bacterial infections – In people who wear contact lenses and do not practice good hygiene.
- Viral infections – Herpes simplex virus is a notorious offender.
- Fungal infections – May result from plant material injuries or infected eye drops.
- Parasitic infections – Acanthamoeba, which is present in water, can infect swimmers who wear lenses.
- Eye injuries – Eye scratches or trauma may progress to ulcers.
- Dry eyes – Decreased tear secretion may cause the cornea to dry and ulcerate.
- Vitamin A deficiency – More prevalent in developing nations and children.
- Misuse of contact lenses – Sleeping in lenses or failing to clean them properly heightens risk.
Who Is at Risk of Getting a Corneal Ulcer?
Anyone can get a corneal ulcer, certain individuals are at greater risk:- Contact lens users
- Individuals with compromised immune systems

Corneal Ulcer in Contact Lens Wearers
Contact lenses, if not cleaned and handled with care, can be a big risk factor. Lenses may trap bacteria or other pathogenic microorganisms against the eye. Wearing lenses while sleeping, using outdated lens solutions, or failing to wash hands before putting on lenses are frequent causes. Prevention measures for contact lens wearers:- Always wash your hands before touching your lenses.
- Never sleep with your lenses in.

How Is a Corneal Ulcer Diagnosed?
Your eye care professional will start with a comprehensive eye examination. They may apply a special dye (fluorescein) to bring out the ulcer when viewed under a blue light. In other instances, they may get a sample of the infected tissue to ascertain the specific cause, which assists in determining the most effective treatment.Corneal Ulcer Treatment
Treatment varies depending on the cause:- Bacterial ulcers: Often treated with antibiotic eye drops.
- Viral ulcers: Drops or pill forms of antiviral medicine can be given.
- Fungal ulcers: Need antifungal eye drops, which sometimes are required for weeks.
- Parasitic infection: These take more effort and can require customized drugs.
Can You Treat a Corneal Ulcer Naturally?
Though natural remedies can correct general eye conditions or dryness, a corneal ulcer is a medical emergency, never to be treated with home remedies alone. Delay in treatment can cause permanent blindness. Supportive treatments, though, are:- Putting cold compresses on for pain (in medical guidance)
- Good diet for quicker healing
- Resting the eyes and keeping away from direct light
How Long Does Recovery Take?
Recovery time is based on how severe the ulcer is and how soon treatment is initiated. Simple ulcers heal in a week or two, whereas severe infections take weeks or even months. Follow-up with your doctor every few days is necessary to watch for healing and avoid complications.Prevention of Corneal Ulcer
Prevention of a corneal ulcer is always preferable to treatment. Follow these important tips for prevention:- Avoid touching your eyes with dirty hands
- Use protective eyewear while doing risky tasks (e.g., handling chemicals, gardening)
- Maintain proper contact lens hygiene
- Avoid swimming with lenses on
- Don’t use expired or contaminated eye drops
