Corneal Ulcer
What is Corneal Ulcer
A corneal ulcer is a serious eye condition that occurs when there is an open sore or wound on the cornea, the transparent front part of the eye. It requires prompt treatment . Here are a few key points to know about corneal ulcers:
1. Causes of Corneal Ulcers
Corneal ulcers can develop due to multiple factors, often involving infections or injuries to the eye. Here are some common causes:
- Infections: Bacterial, viral, fungal, or parasitic infections can lead to corneal ulcers.
- Bacterial Infections: Common among contact lens wearers, bacterial infections can quickly worsen if not treated promptly.
- Viral Infections: Herpes simplex virus (HSV) and varicella-zoster virus (which causes shingles) can cause viral corneal ulcers.
- Fungal Infections: Fungal ulcers may occur after eye injuries involving plant material (like tree branches) or prolonged use of contaminated eye drops or contact lenses.
- Parasitic Infections: Acanthamoeba keratitis is a rare but serious infection, often associated with improper contact lens hygiene.
- Eye Injuries: Physical trauma such as scratches, burns, or chemical exposure can damage the cornea, making it vulnerable to infections.
- Dry Eye Syndrome: People with severe dry eye conditions may develop corneal ulcers due to a lack of adequate tear film to protect the cornea. Learn more about Dry Eye Syndrome Treatment.
- Contact Lens Overuse: Wearing contact lenses for extended periods, especially overnight, increases the risk of corneal ulcers. Poor hygiene, using contaminated solutions, or swimming with contact lenses can introduce harmful microorganisms to the eye.
- Underlying Medical Conditions: Autoimmune disorders like rheumatoid arthritis or lupus can trigger corneal ulcers due to inflammation and decreased tear production.
2. Symptoms of Corneal Ulcers
A corneal ulcer can cause significant discomfort and lead to vision problems. Common symptoms include:
- Severe eye pain
- Redness and inflammation
- Blurred or decreased vision
- Excessive tearing or discharge
- Sensitivity to light (photophobia)
- A white or cloudy spot on the cornea
- Swelling of the eyelids
- A feeling of something being stuck in the eye
If you experience any of these symptoms, seek immediate medical attention at Dayal Eye Centre.
3. Diagnosis of Corneal Ulcers
An eye doctor (ophthalmologist) will diagnose a corneal ulcer through a comprehensive eye examination, which may include:
- Slit-lamp Examination: A specialized microscope is used to examine the cornea under high magnification and detect any ulcers.
- Fluorescein Staining Test: A dye is placed in the eye to highlight the ulcer and determine its size and severity under a blue light.
- Corneal Scraping or Culture: In cases of severe infections, the doctor may collect a small sample from the ulcer to identify the exact cause and prescribe the most effective treatment.
4. Treatment of Corneal Ulcers
The treatment of a corneal ulcer depends on its underlying cause. Early intervention is critical to preventing complications and preserving vision.
- Bacterial Ulcers: Treated with antibiotic eye drops, which may need to be applied frequently, sometimes even hourly.
- Viral Ulcers: Antiviral medications in the form of eye drops or oral medications are used to manage viral infections like herpes simplex.
- Fungal Ulcers: Antifungal eye drops or oral medications are required for treating fungal infections. These ulcers often take longer to heal.
- Parasitic Ulcers: Acanthamoeba keratitis requires specific antiparasitic treatments, which can be challenging and prolonged.
- Pain Management: Doctors may prescribe pain-relieving eye drops to reduce discomfort and inflammation.
- Surgical Intervention: In severe cases where the ulcer does not heal with medication, corneal transplantation (Corneal Disease Treatment) may be necessary to restore vision.
5. Prevention of Corneal Ulcers
While not all corneal ulcers are preventable, the following steps can significantly reduce your risk:
- Maintain Proper Eye Hygiene: Wash your hands before touching your eyes or handling contact lenses.
- Use Contact Lenses Safely: Follow the prescribed wearing schedule, clean lenses properly, and avoid wearing them while swimming or sleeping.
- Protect Your Eyes: Use safety goggles or sunglasses when engaging in activities that could lead to eye injury.
- Avoid Rubbing Your Eyes: This can introduce bacteria and worsen eye conditions.
- Stay Hydrated and Manage Dry Eyes: Use artificial tears if you suffer from dry eyes, and drink plenty of water to maintain hydration.
- Regular Eye Checkups: People at higher risk, such as contact lens users and those with autoimmune diseases, should have routine Eye Checkups to detect problems early.
6. Complications of Untreated Corneal Ulcers
If left untreated, a corneal ulcer can lead to:
- Permanent vision loss
- Corneal scarring
- Increased risk of glaucoma
- Spread of infection to other parts of the eye
- Need for a corneal transplant
7. Urgency of Treatment
A corneal ulcer is a medical emergency. Delayed treatment can cause irreversible damage to your eyesight. If you experience any symptoms of a corneal ulcer, seek immediate care from an Paediatric Ophthalmologist to prevent serious complications.
