What Is a Corneal Ulcer?
A corneal ulcer is an open sore on the cornea, the clear outer layer of the eye. This condition is a serious eye emergency that can lead to vision loss if not treated promptly. Corneal ulcers often result from infections, injuries, improper contact lens use, or underlying health conditions.
Common Causes
- Infections: Bacterial, viral, fungal, or parasitic infections are the most common causes. People who wear contact lenses, especially those who sleep in their lenses or do not clean them properly, are at higher risk.
- Trauma: Even minor scratches from fingernails, makeup brushes, or foreign objects can lead to ulcers.
- Underlying Conditions: Dry eye syndrome, vitamin deficiencies, or autoimmune diseases can weaken the cornea and increase the risk of ulcers.
Recognizing the Symptoms
- Severe eye pain or a feeling that something is in your eye
- Redness and excessive tearing
- Blurred vision or sensitivity to light
- Pus or discharge from the eye
If you notice these symptoms, seek immediate medical attention. Corneal ulcers require urgent care to prevent complications like scarring, glaucoma, or blindness.
Treatment Options
Treatment depends on the cause and may include:
- Antibiotic, antiviral, or antifungal eye drops to fight infection.
- Oral pain medication or dilating drops to relieve discomfort.
- Corneal transplant surgery for severe cases that do not respond to medication.
Prevention Tips
- Practice good hygiene: Always wash your hands before touching your eyes or handling contact lenses.
- Follow proper contact lens care: Avoid sleeping in lenses, clean them regularly, and replace them as recommended.
- Protect your eyes: Wear safety goggles during activities that could cause eye injury.
- Manage underlying health conditions: Control conditions like diabetes or autoimmune diseases to reduce your risk.
- Schedule regular eye exams: Early detection of eye issues can help prevent ulcers and other complications.
