What Is a Corneal Ulcer and Why Early Care Is Critical
A corneal ulcer is an open sore that develops on the cornea—the transparent front part of the eye. It usually occurs due to infection, injury, or prolonged eye irritation and can worsen quickly if ignored. Understanding the stages of corneal ulcer helps in recognising severity early and seeking appropriate care before vision damage occurs.
Stages of Corneal Ulcer and How They Progress
Early Stage: Surface Damage and Initial Infection
In the first the stage, the outer epithelial layer gets damaged. Common corneal ulcer symptoms at this stage include eye redness, mild pain, excessive tearing, irritation, and sensitivity to light. Blurred vision may also appear. Early corneal ulcer causes include contact-lens overuse, dry eyes, minor trauma, or bacterial entry.
Progressive Stage: Stromal Involvement
As the ulcer deepens into the corneal stroma, pain increases, and vision becomes cloudier. Discharge, swelling, and a visible white or grey spot may be seen. The severity of corneal ulcer symptoms generally indicates progression. Differentiating bacterial vs fungal corneal ulcer is crucial here, as fungal ulcers tend to worsen slowly, while bacterial ulcers progress rapidly.
Advanced Stage: Deep Ulceration and Risk to Vision
In advanced stages of corneal ulcer, corneal thinning occurs, increasing the risk of perforation. Severe pain, marked vision loss, and heavy discharge are common. Different types of corneal ulcer, including viral or parasitic ulcers, may also reach this stage if untreated.
Healing Stage: Recovery and Scarring
With timely care, healing begins. A common question is how to tell if corneal ulcer is healing. Reduced pain, less redness, improved light tolerance, and clearer vision are signs of recovery, though scarring may remain.
Corneal Ulcer Causes
A corneal ulcer can develop from multiple factors, including:
- Infections:
- Bacterial infections – Common in contact lens wearers, especially when lenses are worn overnight.
- Fungal infections – Often occur after eye trauma with organic material like plant matter.
- Viral infections – Herpes simplex virus is a leading cause.
- Parasitic infections – Acanthamoeba infections are rare but severe.
- Trauma and Eye Injuries:
- Chemical burns, foreign bodies, or scratches on the cornea.
- Underlying Eye Conditions:
- Severe dry eye syndrome, vitamin A deficiency, or eyelid disorders leading to improper eye closure.
Types of Corneal Ulcer
- Bacterial Corneal Ulcer – Rapidly progressing; requires aggressive treatment.
- Fungal Corneal Ulcer – Often misdiagnosed; needs antifungal therapy.
- Viral Corneal Ulcer – Recurrent; commonly caused by herpes simplex.
- Parasitic Corneal Ulcer – Rare but highly resistant to treatment.
Corneal Ulcer Treatment and Effective Management
Corneal ulcer treatment depends on severity and cause. Antibiotic, antifungal, or antiviral eye drops are commonly prescribed. Severe cases may require emergency procedures. Ongoing corneal ulcer management includes medication adherence, follow-ups, avoiding eye strain, and practising eye hygiene. Preventing recurrent corneal ulcer causes plays an essential role in long-term eye health.
Care Tips to Support Healing After Corneal Ulcer
In addition to prescribed treatment, certain precautions can help support healing and prevent complications.
Patients are advised to:
- Avoid contact lens use until complete recovery
- Protect the eyes from dust, smoke, and bright light
- Avoid touching or rubbing the affected eye
- Follow medication schedules strictly
- Attend all follow-up visits with the eye specialist
These measures help ensure smooth recovery and reduce the chances of recurrence.

Do corneal ulcers go away?
With proper treatment, most corneal ulcers can heal within a few weeks. However, the healing time may vary depending on the severity of the ulcer and the individual’s response to treatment.
Will corneal ulceration go away?
Corneal ulceration can go away with appropriate treatment and care. However, it is important to seek medical attention for proper diagnosis and treatment, as untreated corneal ulcers can lead to complications and vision loss.
Is a corneal ulcer a medical emergency?
Corneal ulcers require prompt medical attention, but they may be considered a medical emergency. You must visit an eye doctor within a day and avoid self medication.
What are the four stages of a corneal ulcer?
The four stages of a corneal ulcer are epithelial defect, stromal infiltration, Descemetocele, and corneal perforation. Early detection and treatment are crucial to prevent the ulcer from progressing to more severe stages.
What Are the Early Symptoms of a Corneal Ulcer?
Early corneal ulcer symptoms include eye redness, pain, sensitivity to light, and blurred vision. Immediate treatment is necessary to prevent progression.
How Can a Corneal Ulcer Be Prevented?
- Proper contact lens hygiene
- Avoiding eye trauma
- Immediate treatment of eye infections
How Long Does It Take for a Corneal Ulcer to Heal?
Mild ulcers may heal within a few days, while severe cases may take weeks or require surgery.
What Happens if a Corneal Ulcer Is Left Untreated?
It can lead to permanent blindness, corneal perforation, or the need for a transplant.
