Corneal Ulcer Treatment in the Bay Area – Eye Infection Symptoms & Emergency Care
A corneal ulcer is an open sore on the cornea, the clear front surface of the eye that covers the iris (colored part). It is a serious eye infection that can progress quickly and requires prompt medical attention to protect vision.
Unlike minor eye irritation, a corneal ulcer is considered an ocular emergency. Without timely treatment, it can lead to permanent vision loss.
What Causes a Corneal Ulcer?
Most corneal ulcers are caused by infection, but they can also develop after injury or underlying eye conditions.
Common causes include:
Bacterial Infections
- Most common cause
- Higher risk in contact lens wearers, especially overnight use
Fungal Infections
- More likely with prolonged steroid eye drop use
- Can occur after injury involving organic material
Dry Eye & Eyelid Conditions
- Reduced tear protection increases infection risk
- Conditions that prevent full eyelid closure (such as Bell’s palsy)
Viral Infections
- Herpes simplex virus (cold sores)
- Varicella virus (chickenpox or shingles)
Eye Injuries or Trauma
- Scratches from fingernails, debris, or foreign particles
- Damage allows bacteria to enter and infect the cornea
Chemical Exposure
- Burns or irritation from chemicals can damage the cornea
Contact Lens Use & Risk Factors
Contact lens wear is one of the leading risk factors. The risk of corneal ulcers increases significantly when lenses are worn overnight or not properly cleaned.
Contact lenses can contribute to ulcers by:
- Trapping bacteria against the cornea
- Reducing oxygen supply to the eye
- Causing small scratches that allow infection to develop
- Introducing debris under the lens surface
Symptoms of a Corneal Ulcer
Symptoms are typically more severe than a simple eye irritation and may include:
- Red eye
- Severe eye pain
- Feeling like something is stuck in the eye
- Excessive tearing
- Thick discharge or pus
- Blurred or reduced vision
- Sensitivity to light
- Swollen eyelids
- A visible white spot on the cornea (in more advanced cases)
If you are experiencing these symptoms, prompt evaluation is critical.
When to Seek Immediate Care
You should be evaluated right away if you notice:
- Significant or worsening eye pain
- Discharge from the eye
- Sudden vision changes
- History of eye injury or chemical exposure
- Persistent sensation of something in the eye
Corneal ulcers can worsen quickly, so early treatment is essential.
How Corneal Ulcers Are Treated
Treatment depends on the cause and severity but often begins immediately after diagnosis.
Initial Steps
- Remove contact lenses right away
- Avoid touching or rubbing the eye
- Maintain good hand hygiene
Medications
- Antibiotic eye drops (often used frequently, sometimes hourly)
- Antiviral or antifungal medications when indicated
- Pain control with oral medications or medicated eye drops
Advanced Care
- Close monitoring by an ophthalmologist
- Hospitalization in severe cases
- Avoiding eye patching if infection is suspected, as it can worsen bacterial growth
Surgical Treatment
If the ulcer does not respond to medication or threatens to damage the eye, emergency surgery such as a corneal transplant may be required.
Why Prompt Treatment Matters
A corneal ulcer can progress rapidly. Without treatment, it can lead to:
- Corneal scarring
- Vision loss or blindness
- Corneal perforation
- Secondary conditions such as glaucoma or cataracts
Early diagnosis and treatment significantly improve outcomes.
