What Is Corneal Ulcer (Keratitis)?
A corneal ulcer, also called keratitis, is an open sore on the cornea, the clear front part of the eye. It usually happens due to infection or injury, causing inflammation and damage to the corneal tissue. It is a medical emergency that needs immediate treatment.
The cornea works like a windshield, protecting the eye from dust and germs. When it gets damaged, it becomes more prone to infections, just like a crack in a windshield.
Common symptoms include redness, watering, severe eye pain, blurred vision and discharge. This condition can develop suddenly or gradually and can affect anyone, but people who wear contact lenses, have dry eyes or have had eye injuries are at higher risk.
If not treated on time, a corneal ulcer can lead to permanent vision loss or even blindness. Early diagnosis and immediate treatment are very important to protect your vision.
What Are the Corneal Ulcer (Keratitis) Symptoms You Should Not Ignore?
Corneal ulcer (keratitis) symptoms should never be ignored, as they can quickly damage your vision and may lead to permanent vision loss if not treated on time. Seek immediate medical care, as symptoms may start mild but can worsen quickly.
Common corneal ulcer (keratitis) symptoms include:
- Severe eye pain: You may feel sharp, intense pain in the eye that does not go away and often makes it hard to open the eye.
- Blurred or reduced vision: You may notice sudden changes in your vision, such as blurriness or difficulty seeing clearly.
- Thick discharge or excessive watering: The eye may produce yellow or pus-like discharge or tear up more than usual.
- White or grey spot on the cornea: A visible spot or cloudy patch may appear on the front colored part of the eye. This is a sign of infection or damage.
- Very red or bloodshot eye: The eye may look extremely red due to inflammation and irritation of the cornea.
- Strong sensitivity to light (photophobia): Bright light may cause discomfort or pain, making it difficult to keep your eyes open.
- Feeling like something is stuck in the eye: You may constantly feel a foreign body sensation, even if nothing is actually there.
- Swollen or puffy eyelids: The eyelids may become swollen, red and tender due to infection.
Early symptoms are mild; if you notice any of these signs, see an eye specialist immediately. Delayed treatment can lead to corneal scarring and permanent vision loss.
When Should You See an Eye Specialist for Corneal Ulcer (Keratitis)?
A corneal ulcer (keratitis) is a serious eye problem that needs immediate attention from an eye doctor. Get urgent care if you have strong eye pain, blurry vision, a white or gray spot on your eye, high sensitivity to light or discharge - especially after an eye injury or if you wear contact lenses.
When to see an eye specialist right away:
- Severe eye pain and redness that doesn’t improve
- Sudden blurry or reduced vision
- White or gray spot on the eye, swelling, or discharge
- Injury to the eye or feeling something stuck in it
- Symptoms getting worse even after treatment
- Strong discomfort in bright light
- Contact lens users with irritation or redness
If left untreated, a corneal ulcer can lead to permanent vision loss or even blindness. Getting timely medical help can protect your eyesight.
What Causes Corneal Ulcer (Keratitis)?
A corneal ulcer (keratitis) is an open sore on the surface of the eye. It usually happens due to infections, injury or very dry eyes. The most common cause is a bacterial infection from contact lens use. It can also be caused by viruses (like herpes), fungi or parasites. Early treatment is important to avoid vision loss.
Common causes of keratitis include:
- Eye injury: If something scratches or damages your cornea, it can cause keratitis. The injury can also let germs enter and cause infection.
- Contact lenses: Not cleaning lenses properly, wearing them for too long or sleeping with them can increase the risk of infection and lead to keratitis.
- Dry eyes: When your eyes don’t produce enough tears, they lose natural protection, making it easier for infections to occur and increasing the risk of keratitis.
- Fungi or parasites: These germs can grow on contact lenses or their cases. If the lens is not clean, they can enter the eye and cause infection. Poor hygiene or wearing lenses too long increases the risk.
- Viruses: Herpes viruses (like herpes simplex and herpes zoster) can also cause keratitis.
- Bacteria: Common ones causing keratitis include Staphylococcus, Streptococcus and Pseudomonas.
- Eyelid problems: If the eyes are not closing properly, it leads to dryness, thus may lead to keratitis.
- Health conditions: Certain health issues like dry eyes, vitamin A deficiency or diabetes might lead to keratitis.
- Immune conditions: If you have an autoimmune disorder, your immune system may attack your own eye tissues or become weaker, making it easier for keratitis to develop.
- Contaminated water: Water in swimming pools, rivers, lakes or hot tubs may contain harmful germs. These can enter your eyes while swimming and cause infection, especially if your cornea is already damaged (for example, from overusing contact lenses).
- Other eye conditions: If you already have a corneal problem, allergic conjunctivitis or have had eye surgery, your eye may become more sensitive and weaker, making it more susceptible to infections that can lead to keratitis.
A healthy cornea usually resists infection, but any damage (like scratches or lens overuse) increases the risk. Understanding the cause is key to determining the right treatment and preventing recurrence.
What Are the Risk Factors for Corneal Ulcer (Keratitis)?
Corneal ulcers (keratitis) are mainly caused by infections - bacterial, viral, fungal or parasitic. These often happen due to poor contact lens hygiene, eye injuries or existing eye problems. Risk increases with habits or having severe dry eyes, previous eye damage or a weak immune system.
The following are the main risk factors that can increase the chances of developing corneal ulcers (keratitis) and should not be ignored.
Contact lenses (most common cause):
- Sleeping while wearing lenses
- Not cleaning or storing lenses properly
- Using tap water or unsafe solutions
- Wearing lenses while swimming or in hot tubs
Eye injury:
- Scratches from nails, makeup tools or objects
- Injury from plants or soil (can cause fungal infection)
- Chemical or heat burns
Eye surface problems:
- Severe dry eyes
- Eyelid issues that prevent proper eye closing
- Past eye surgery or infections (like herpes)
Medicines and health conditions:
- Long-term use of steroid eye drops
- Weak immunity (due to diabetes, poor nutrition or serious illnesses)
- Vitamin A deficiency
These factors weaken the eye’s natural defense, increasing the risk of infections and corneal ulcers. As they may act together, regular eye check-ups and a healthy routine help in early detection and better care.
Did You Know?
- Corneal ulcers can affect one or both eyes.
- Early treatment can prevent permanent scarring and vision loss.
- Avoid rubbing eyes or using over-the-counter eye drops without consultation.
- Corneal ulcers are a medical emergency if accompanied by pain, discharge or vision loss.
What Are the Different Types of Corneal Ulcer (Keratitis)?
Corneal ulcers (keratitis) are mainly of two types based on their cause:
Infectious keratitis:
This type is caused by germs such as:
- Viruses (like herpes or chickenpox virus)
- Fungi
- Bacteria
- Parasites
- It can also be linked to vitamin A deficiency
- Improper contact lens uses, like poor cleaning, wearing lenses too long or swimming with them.
Non-infectious keratitis:
This type is not caused by infection and may happen due to:
- Eye injury or scratches
- Too much exposure to UV light
- Allergies
- Dryness or inflammation of the eye
- Something stuck in the eye (foreign body)
- Improper use of contact lenses
Both types can harm your eyes, so proper care and early treatment are important.
How Is Corneal Ulcer (Keratitis) Diagnosed?
Corneal ulcers are diagnosed by an eye specialist using a detailed eye exam. The doctor checks the cornea closely and may do simple tests to find the cause and severity.
Common diagnostic methods:
- Slit-lamp exam: A special microscope with bright light is used to examine the cornea and see the size and depth of the ulcer.
- Fluorescein staining: A dye is put in the eye to highlight damaged areas, which glow under blue light.
- Corneal culture tests: A small sample from the ulcer may be taken to check for bacteria, fungi or parasites in the lab.
- Visual acuity test: This test checks how clearly you can see objects at near and far distances, usually using an eye chart.
- Medical history: The doctor asks about symptoms, eye injury or contact lens use to understand the cause.
- Advanced tests: In some cases, special imaging tests are used to view deeper layers of the cornea, especially for severe or non-healing ulcers.
Note: Numbing drops are used before taking any sample, so it is usually painless.
Early and accurate diagnosis, along with a review of your symptoms and medical history, helps identify the cause and severity of the corneal ulcer, allowing timely treatment and preventing serious vision problems.
What Are the Complications of Corneal Ulcer (Keratitis)?
Corneal ulcers are serious eye problems that can harm your vision if not treated on time. They may lead to long-term damage and, in severe cases, even loss of vision.
Major complications include:
- Cataract: Long-term inflammation can make the eye lens cloudy, leading to blurred vision.
- Irregular astigmatism: The cornea may heal unevenly, causing distorted or unclear vision.
- Corneal scarring: After healing, a white spot or scar can form on the eye, making your vision blurry.
- Endophthalmitis: The infection can spread inside the eye, which is very serious and may even lead to loss of the eye.
- Corneal perforation: In severe cases, a small hole can develop in the cornea. This is an emergency.
- Vision loss or blindness: If the infection becomes severe, it can reduce your vision or even cause permanent blindness.
- Secondary glaucoma: Eye pressure can increase and damage the optic nerve, affecting vision.
Expert advice: If you notice symptoms like pain, redness or blurred vision, get your eyes checked immediately to avoid these complications.
What Are the Available Corneal Ulcer (Keratitis) Treatment Options?
Corneal ulcers can have different causes, so the treatment depends on the reason behind it and its severity. Some treatments are specific, while others help reduce symptoms and support healing.
Common treatment options include:
Medicines
These can include -
- Antibiotic, antiviral or antifungal eye drops.
- Oral medications for severe infections.
- Lubricating eye drops to relieve dryness and irritation.
Tarsorrhaphy (keeping the eye closed)
In some cases, we may keep your eye closed for a period of time - either with stitches or with injections to help the cornea heal better.
Protective contact lenses
Special lenses (like bandage or scleral lenses) are used to protect the eye and help it heal faster.
Pain management
You may be given pain-relief medicines to keep you comfortable during healing.
Surgery
If the ulcer does not improve with medicines, surgery may be needed. In severe cases, a corneal transplant might be required.
Follow-up care
You should go for regular check-ups to make sure your eye is healing properly.
The treatment depends on your condition, so it’s important to follow your eye specialist’s guidance and not delay care. Early and appropriate treatment reduces the risk of scarring, vision loss and complications.
