Corneal Ulcer Treatment in Palamu
Prompt, evidence-based management of corneal infections at Palamu Neuro & Eye Care, preventing vision loss through early diagnosis and targeted antimicrobial therapy.
What is Corneal Ulcer (Infectious Keratitis)?
A corneal ulcer, or infectious keratitis, is an open sore that forms on the cornea. It is an extreme medical emergency requiring immediate, aggressive treatment by Dr. Dibya Prabha.
Symptoms of Corneal Ulcer (Infectious Keratitis)
- •Severe, unrelenting eye pain
- •Intense redness of the eye
- •A visible white or gray spot on the normally clear cornea
Clinical Observations at Palamu Neuro & Eye Care
Dr. Dibya Prabha at Palamu Neuro & Eye Care sees a high volume of fungal corneal ulcers in farmers from Jharkhand's paddy-growing regions — caused by vegetative trauma from rice stalks, hay, and thorns during field work. These patients often present 5–7 days after injury, having used steroid-containing eye drops from local chemists that worsen fungal infections.
Standard medical literature states:
Standard corneal textbooks describe infectious keratitis as a microbial infection of the cornea, with bacterial causes most common in contact lens wearers and fungal keratitis more common in agricultural settings.
We perform corneal scraping for KOH mount and Gram stain on the day of presentation to guide antimicrobial selection. We counsel patients and local chemists in Hindi that using steroid eye drops ('safed boond') on a red, painful eye after a plant injury can cause the ulcer to 'explode' — making a treatable infection sight-threatening.

Causes & Risk Factors
- •Bacterial infections, often linked to contact lens hygiene
- •Fungal infections, common in agricultural settings
- •Viral infections, particularly from herpes simplex
Diagnostic Tests
Corneal Scraping and Microbiological Workup
The gold standard diagnostic procedure. Under topical anaesthesia and slit-lamp magnification, Dr. Dibya Prabha collects corneal scrapings from the advancing edge and base of the ulcer using a sterile Kimura spatula or surgical blade. The sample is smeared for Gram staining (bacteria) and KOH wet mount (fungal hyphae), and inoculated onto culture media including blood agar, chocolate agar, and Sabouraud dextrose agar. Culture and sensitivity results guide targeted antimicrobial therapy, typically available within 48 to 72 hours.
Slit-Lamp Biomicroscopy with Serial Photography
Detailed slit-lamp examination documents ulcer size (in millimetres), depth (percentage of stromal thickness), infiltrate morphology, epithelial defect staining pattern with fluorescein, presence of hypopyon and its height, anterior chamber reaction, and endothelial plaque. Serial photographs taken at each visit at Palamu Neuro & Eye Care, Palamu, allow objective monitoring of healing, failure to respond, or worsening that would prompt a change in therapy.
Anterior Segment OCT
High-resolution anterior segment OCT provides cross-sectional imaging of the cornea, allowing precise measurement of stromal thinning, infiltrate depth, descemetocele formation, and corneal thickness. It is particularly useful in monitoring deep fungal ulcers and post-herpetic stromal necrosis, where clinical assessment of depth may be unreliable. AS-OCT helps Dr. Dibya Prabha determine when a cornea is at risk of perforation and may require emergency tectonic intervention.
Treatment Approach
Corneal ulcer management at Palamu Neuro & Eye Care, Palamu, follows a protocol of urgent diagnosis, immediate initiation of broad-spectrum antimicrobials, and daily monitoring until the infection is controlled. Dr. Dibya Prabha employs a stepwise strategy that is adjusted dynamically based on clinical response, microbiology results, and the development of any complications.
- Immediate Corneal Scraping
- Taking a tiny scrape of the ulcer for urgent Gram stain and culture.
- Intensive Antimicrobial Therapy
- Administering fortified, high-concentration antibiotic or antifungal eye drops.
When to See a Doctor
- !You develop sudden, severe eye pain with redness, tearing, and light sensitivity, especially after any eye injury involving soil, plant material, or a foreign body.
- !You notice a white or grey spot on your cornea that was not there before, regardless of whether the eye is painful or not.
- !You are a contact lens wearer and experience eye discomfort, redness, or blurred vision that does not resolve immediately after removing your lenses.
- !An episode of 'red eye' that was initially mild does not improve within 24 hours and instead worsens with increasing pain or visual decline.
- !You have a history of cold sores or shingles and develop eye pain with a bpalamung corneal pattern or a vesicular rash around the eye.
- !You have had any eye surgery, corneal abrasion, or ocular surface disease and subsequently develop worsening pain, haze, or discharge that is not explained by the original condition.
Frequently Asked Questions
What is a corneal ulcer and why is it an emergency?
A corneal ulcer, or infectious keratitis, is an open sore on the cornea characterised by epithelial defect with underlying stromal infiltration and inflammation, usually caused by microbial infection. It is a true ocular emergency because the cornea is the transparent window of the eye and any scarring or thinning can permanently impair vision. Bacterial corneal ulcers can progress rapidly, with some aggressive organisms like Pseudomonas aeruginosa liquefying the corneal stroma and perforating the eye within 24 to 48 hours. Fungal keratitis, more common in agricultural regions of India including Jharkhand, follows a more indolent but equally destructive course. Dr. Dibya Prabha at Palamu Neuro & Eye Care, Palamu, prioritises immediate corneal scraping for microbiological diagnosis and initiates empiric broad-spectrum antimicrobial therapy on the same day of presentation to halt the infective process.
What are the common causes and risk factors for corneal ulcer?
Corneal trauma with vegetative matter such as a tree branch, paddy leaf, or thorn is the most significant risk factor for fungal keratitis, especially in agricultural workers. Contact lens wear, particularly extended or overnight wear and poor lens hygiene, is a major risk factor for bacterial and acanthamoeba keratitis. Pre-existing corneal surface disease including dry eye, chronic blepharitis, entropion with trichiasis (in-turned eyelashes rubbing on the cornea), and exposure keratopathy compromise the epithelial barrier. Topical corticosteroid use without antibiotic cover in a misdiagnosed red eye can suppress immunity and flare a latent infection. Malnutrition, diabetes mellitus, and systemic immunosuppression are additional predisposing factors that impair corneal healing. Ocular surface trauma from dust, sand, or minor industrial injuries is common in Palamu and surrounding districts.
How is corneal ulcer diagnosed and treated at Palamu Neuro & Eye Care?
Diagnosis begins with a detailed history and slit-lamp examination documenting ulcer size, depth, infiltrate characteristics, and anterior chamber reaction. Dr. Dibya Prabha performs corneal scraping under topical anaesthesia for Gram staining, potassium hydroxide wet mount (to detect fungal hyphae), and culture on blood agar, chocolate agar, and Sabouraud dextrose agar. Treatment is initiated immediately based on clinical features and smear results: fluoroquinolone monotherapy or fortified cephalosporin and aminoglycoside combinations for bacterial ulcers, natamycin 5% for filamentous fungal ulcers, and oral voriconazole or intrastromal antifungal agents for deep fungal keratitis. Patients are reviewed daily during the acute phase at Palamu Neuro & Eye Care, Palamu, with serial slit-lamp photography to track healing.
Can a corneal ulcer cause permanent vision loss?
Yes, corneal ulcer is one of the most common causes of monocular corneal blindness, particularly in developing countries. After the infection resolves, residual corneal scarring (leucoma or nebula) in the visual axis permanently reduces visual acuity. Severe ulcers can lead to corneal perforation, iris prolapse, endophthalmitis (intraocular spread of infection), or secondary glaucoma. Even successfully treated ulcers may leave irregular astigmatism that affects the quality of vision. Dr. Dibya Prabha emphasises that early presentation is the single most important determinant of outcome; ulcers presenting within 48 hours of symptom onset have a significantly better prognosis than those left untreated for a week or more. For patients with post-infectious corneal scars, Palamu Neuro & Eye Care provides counselling on optical iridectomy, rigid gas permeable contact lenses, and keratoplasty options when indicated.
