Keratitis and Corneal Ulcers both affect the cornea. It is the transparent outer part of the eye and is highly vulnerable to eye health issues.
These two conditions often get confused with each other.
While both can be painful and potentially vision-threatening, their causes, symptoms, and treatments are distinct.
This article will draw a comparison between Keratitis vs Corneal Ulcers to help you better understand these eye conditions.
What is Keratitis
Keratitis is the inflammation of the cornea. It can develop due to various causes, including eye infections, trauma, and underlying eye diseases.
Bacterial, fungal, or viral infections are common factors behind Keratitis.
Scratches, cuts, or foreign objects in the eye can also trigger Keratitis.
Dry eyes can lead to dry spots on the cornea, making it more vulnerable to inflammation.
Conditions like Blepharitis (inflammation of the eyelids) and Pink Eye (Conjunctivitis) can sometimes result in Keratitis.

What is a Corneal Ulcer
A Corneal Ulcer is a more specific and serious condition than Keratitis.
It involves an infection-related open sore or erosion on the corneal surface.
Bacterial eye infections caused by Pseudomonas or Staphylococcus are the most common cause of Corneal Ulcers.
In some cases, fungi like Fusarium or Aspergillus can infiltrate the cornea, leading to ulceration.
Although less frequent, certain viral infections can cause Corneal Ulcers.
A deep corneal injury, often from foreign objects or severe scratches, can create an opening in the cornea and result in an ulcer.
Symptoms of Keratitis
The symptoms of Keratitis can vary depending on the underlying cause and type of Keratitis.
But some common symptoms include eye pain, blurry vision, redness, etc.
- Eye Pain: Individuals with Keratitis often experience a sharp, aching, or foreign body sensation in the affected eye
- Redness: The affected eye may appear red and bloodshot
- Light Sensitivity: Photophobia, or sensitivity to light, is a typical symptom of Keratitis
- Excessive Tearing: Watery eyes are a common response to eye irritation
- Blurry Vision: Vision can become blurred or hazy due to corneal inflammation
- Discharge: In some cases, there may be a discharge from the eye, often with a yellowish or greenish touch

Symptoms of Corneal Ulcer
Source: @gettyimagesCorneal Ulcers typically present more severe and distinct symptoms than Keratitis.
These symptoms may include eye pain, redness, reduced vision, etc.
- Severe Eye Pain: The pain associated with Corneal Ulcers is often described as intense and continuous
- Redness: The affected eye may exhibit pronounced redness and inflammation. There may be a lot of redness and swelling in the affected eye
- Reduced Vision: Vision loss can be significant, and the eye may become cloudy or develop a white spot at the site of the ulcer
- Excessive Tearing: Like Keratitis, tearing is common in Corneal Ulcers
- Purulent Discharge: A yellowish or greenish discharge is typical, and the eye may be stuck shut upon waking
- Photophobia: Light sensitivity is more prominent in corneal ulcers due to the extent of corneal damage
Diagnosis and Treatment
Diagnosing Keratitis and Corneal Ulcers involves a comprehensive eye examination.
An eye care professional may use a slit lamp to examine the cornea closely during this examination.
They may also take a sample of eye discharge for laboratory analysis to determine the underlying cause, particularly ulcers.
Treatment for Keratitis
Treatment for Keratitis varies depending on the underlying cause. It may include eye drops, oral medications, etc.
- Antibiotic, antifungal, or antiviral eye drops or ointments
- Pain relievers to manage discomfort
- Lubricating eye drops to alleviate dryness
- Avoiding contact lens use during treatment
In severe cases, oral medications or hospitalization may be necessary.

Treatment for Corneal Ulcers
Corneal ulcers often require more aggressive treatment.
These treatment options may include antifungal or antiviral medications, eye drops, etc.
- Broad-spectrum antibiotic eye drops or ointments to target bacterial infections
- Antifungal medications for fungal ulcers
- Antiviral drugs for viral ulcers
- Cycloplegic eye drops to alleviate pain
Sometimes, a therapeutic contact lens may protect the cornea during healing.
Severe corneal ulcers may require surgical intervention, such as corneal transplantation.

Conclusion
Keratitis and Corneal Ulcers affect the cornea and share some similar symptoms.
But, they are distinct conditions with different underlying causes, severity, and treatment approaches.
Understanding the major differences between Keratitis vs Corneal Ulcer is essential for immediate diagnosis and effective management.
If you experience any eye discomfort or symptoms, it is crucial to get professional medical advice to ensure the health and safety of your vision.
Frequently Asked Questions
How do I distinguish between the pain of Keratitis and a Corneal Ulcer?
The pain from a Corneal Ulcer is usually more intense and continuous than Keratitis, making it a distinct symptom for differentiation.
See our Recommendations
Can you wear contact lenses while being treated for Keratitis or a Corneal Ulcer?
Yes, you can wear contact lenses, but it is not advisable when treating either condition. They can affect the healing process and worsen the condition. Consult your eye specialist for guidance.
See our Recommendations
How do eye injuries and trauma contribute to the development of Keratitis?
Eye injuries, such as scratches or the presence of foreign bodies, can disrupt the cornea’s protective barrier, rendering it susceptible to infections. These types of injuries are common catalysts for traumatic Keratitis.
See our Recommendations
Are there lifestyle factors that can heighten the risk of developing Keratitis?
Yes, certain lifestyle activities can increase the risk of Keratitis. These include swimming in contaminated water sources, improper use of eye makeup, and prolonged exposure to sunlight without adequate eye protection.
See our Recommendations
What is the typical recovery duration for Keratitis?
Recovery time for Keratitis can vary significantly depending on its type and severity. Milder cases often resolve within a few days, while more severe forms may require several weeks to months to recover.
See our Recommendations
Is Keratitis the same as Corneal Ulcer?
No, keratitis is not the same as a corneal ulcer. While both conditions affect the cornea, they are distinct. Keratitis is an inflammation of the cornea, whereas a corneal ulcer is an open sore or erosion on the corneal surface.
