What is Corneal Ulcer?
A corneal ulcer is a serious condition involving a defect in the corneal epithelium that extends into the underlying stroma. It commonly affects individuals who wear contact lenses and typically presents with symptoms such as eye pain, blurry vision, and sensitivity to light.
Prompt treatment is crucial as corneal ulcers can lead to significant vision loss and various complications, including corneal scarring or perforation, glaucoma, cataracts, and synechiae formation. If left untreated, bacterial keratitis, which can result from corneal ulcers, may progress to endophthalmitis, potentially leading to loss of the eye.
In the United States, the annual incidence of corneal ulcers ranges between 30,000 and 75,000 cases, with a notable portion of corneal transplants being performed to manage infectious keratitis. Recognizing the signs of corneal ulcers promptly is crucial to initiating treatment and arranging urgent ophthalmologic evaluation.

Precautions
Symptoms
- Pain: Ranging from mild to severe, with Acanthamoeba keratitis often causing intense pain.
- Photophobia: Sensitivity to light, causing discomfort or pain.
- Conjunctival Injection: Redness or inflammation, especially in bacterial and HSV keratitis.
- Blurred Vision: Particularly noticeable in HSV keratitis or fungal infections.
- Foreign Body Sensation: Feeling of something gritty in the eye, common in HSV and bacterial keratitis.
- Dendritic Lesions: Branching patterns seen in HSV keratitis.
- Gray-White Feathery Lesions: Dry, gray-white feathery lesions in fungal infections.
- Superficial, White, Raised Colonies: White, raised colonies with defined borders in yeast-related ulcers.
- Pain Out of Proportion: Severe pain disproportionate to exam findings, seen in Acanthamoeba keratitis.
- Crescent-Shaped Damage: Crescent-shaped damage in the limbal region seen in peripheral ulcerative keratitis due to autoimmune disease.
Treatments
- Bacterial Ulcers: Topical fluoroquinolone antibiotics like ciprofloxacin or ofloxacin are first-line. Severe cases may need hospitalization with systemic antibiotics such as ceftriaxone, especially for gonococcal ulcers. Corneal culture is recommended for large, central ulcers.
- Herpetic Ulcers (HSV): Topical antivirals like trifluridine or acyclovir are used, often with adjuvant topical steroids. Oral antivirals like acyclovir or valacyclovir may also be prescribed.
- Fungal Ulcers: Natamycin is the primary treatment, with amphotericin B as an alternative. Voriconazole is less effective and has more toxicity.
- Acanthamoeba Keratitis: Treatment involves epithelial debridement and months of antiamoebic therapy, typically with chlorhexidine and polyhexamethylene biguanide. Additional agents may be added in severe cases.
- Peripheral Ulcerative Keratitis (PUK): Requires systemic immunosuppressants and cytotoxic agents, managed jointly by a rheumatologist and ophthalmologist. Close monitoring and frequent blood work are essential.
Precautions
- Avoid Eye Rubbing: Prevents worsening or introducing more bacteria/fungi.
- Eye Protection: Wear protective eyewear to prevent trauma.
- Hygienic Contact Lens Use: Proper cleaning and avoiding wearing lenses in water.
- Seek Prompt Medical Attention: Address symptoms promptly to prevent complications.
- Adhere to Treatment: Strictly follow prescribed regimen for effective healing.
- Avoid Irritants: Stay away from substances that can worsen eye inflammation.
- Monitor for Complications: Watch for worsening symptoms and report promptly.
- Regular Follow-up: Attend scheduled appointments to track progress and adjust treatment.
