Diagnosing and Treating Corneal Ulcers
Causes of Corneal Ulcers
Corneal ulcers develop when the surface of the cornea is damaged and microorganisms or other factors trigger inflammation. Knowing the different causes helps you reduce risks and seek help quickly.
Germs can invade a weakened cornea and create an ulcer.
- Bacteria such as Pseudomonas, Staphylococcus, and Streptococcus, often linked to improper contact lens use
- Viruses like herpes simplex or varicella-zoster that may flare up and attack the cornea
- Fungi that enter the eye after injuries involving plant material or soil
- Parasites such as Acanthamoeba found in water that contact lens wearers may encounter
Not every ulcer comes from an infection; many result from mechanical or medical issues.
- Eye injuries including scratches, punctures, or burns
- Chronic dry eye that weakens natural defenses
- Incomplete eyelid closure, as in Bell’s palsy, exposing the cornea
- Chemical irritation or medication toxicity
- Autoimmune disorders that inflame or damage corneal tissue
Certain habits and conditions raise the chance of developing an ulcer.
- Overnight or extended contact lens wear with poor hygiene
- History of viral eye infections
- Persistent dry eyes
- Eyelid abnormalities preventing full closure
- Frequent use of steroid eye drops
- Recent eye surgery or trauma
- Systemic illnesses such as diabetes that slow healing
Recognizing Symptoms
Early identification of symptoms leads to faster treatment and better outcomes. If you notice any of the following signs, seek an eye evaluation promptly.
A sharp, aching, or throbbing pain that often worsens with blinking may signal a developing ulcer.
Pronounced redness around the cornea, accompanied by swollen eyelids, indicates active irritation or infection.
Blurred, hazy, or distorted vision can occur as the ulcer disrupts the normally clear corneal surface.
Photophobia, or discomfort in normal lighting, is common and may cause patients to seek darker environments.
Watery, mucus, or pus-like discharge can crust the lashes and signal bacterial involvement.
A grayish-white spot on the cornea represents active infection or tissue breakdown requiring immediate care.
Diagnosis and Evaluation
A thorough eye examination helps pinpoint the cause and severity of a corneal ulcer so treatment can begin right away.
Our specialist reviews your general and ocular health, symptoms, medications, and environmental factors to tailor the exam.
Quick measurements provide baseline information about visual function.
- Visual acuity using a letter chart
- Depth perception assessment
- Color vision screening
- Eye muscle movement testing
- Peripheral vision check
- Pupil response evaluation
Advanced tools allow close inspection of eye structures and internal pressure.
- External examination of lids and surface
- Slit-lamp microscopy of the cornea
- Intraocular pressure measurement
- Dilated retinal (fundus) examination to assess optic nerve and vessels
Treatment Options
The choice of treatment depends on the cause, depth, and severity of the ulcer. Early and consistent therapy is vital for healing.
Topical and oral drugs fight infection, soothe inflammation, and ease discomfort.
- Antibiotic eye drops for bacterial ulcers
- Antiviral drops or pills for viral causes
- Antifungal medications for fungal infections
- Cautious use of corticosteroid drops after infection control to limit scarring
- Over-the-counter pain relievers to reduce discomfort
Surgery is considered when medication alone cannot restore corneal health or clarity.
- Corneal transplant to replace severely damaged tissue with healthy donor tissue
- Debridement to remove infected or necrotic material and promote healing
Prevention Tips
Protecting the cornea from injury and infection is the best strategy for avoiding ulcers.
Clean, store, and replace lenses as directed, and avoid overnight wear unless specifically advised.
Use safety glasses or goggles during sports, yard work, or when handling chemicals to guard against injury.
Wash hands before touching the eyes and never share makeup, towels, or other items that contact the eye area.
Seek an eye examination for any injury, redness, or pain to prevent minor issues from becoming ulcers.
When to Seek Emergency Care
Some symptoms indicate the ulcer may be worsening and require urgent attention.
If you notice any of these signs, arrange an immediate eye evaluation.
- Sudden or rapidly increasing eye pain
- New or worsening vision loss or double vision
- Marked increase in redness or swelling
- Thick or pus-like discharge
- Extreme sensitivity to light
Frequently Asked Questions
The answers below address common concerns about corneal ulcers and their care.
No. Without medical care, an ulcer can progress, cause scarring, and lead to permanent vision loss.
Lenses can trap microorganisms against the cornea, and sleeping in lenses or poor cleaning habits further increase the chance of infection.
An abrasion is a superficial scratch that often heals quickly. An ulcer is a deeper sore that usually involves infection and needs prompt treatment.
Resume lens use only after the ulcer has fully healed and our doctor confirms that the cornea is healthy.
Bacterial ulcers are generally not contagious, but viral causes, such as herpes simplex, can spread through contact with infected eye secretions.

Came in with an extremely painful tear in my cornea, and the doctor could not have been more helpful, professional or nicer ended up pulling something out of my eye and giving me instant relief.
