Veterinary Guide to Ulcerative Keratitis (Corneal Ulcers) in Dogs (2025)🐶 

By Dr. Duncan Houston BVSc

🔍 Introduction

Ulcerative keratitis describes corneal ulcers—painful erosions that penetrate the epithelium and sometimes stroma. Prompt diagnosis and tailored treatment protect your dog’s vision and comfort in 2025 and beyond. 👁️

💡 What Are Corneal Ulcers?

• Superficial erosions affect epithelium only; deeper stromal ulcers penetrate into the stroma; descemetoceles reach Descemet’s membrane.
• Fluid accumulates within the stroma, causing corneal opacity and pain.

⚠️ Common Causes

• Trauma: scratches from grass, nails, sticks, chemical exposure.
• Pre-existing issues: KCS (dry eye), dystrophy, entropion, distichiasis, endocrine diseases.
• Infections: bacterial, fungal, or immune-mediated conditions.

🚨 Clinical Signs

• Severe ocular pain: squinting, blinking, pawing at eye, photophobia.
• Discharge, corneal haze, redness, blood vessel growth.
• Miosis due to reflex uveitis; deeper ulcers may perforate and lead to vision loss.

🔬 Diagnostic Steps

• Fluorescein stain: highlights ulcers by dye retention.
• Evaluate tear production (Schirmer test), corneal sensitivity, eyelid conformation, and rule out underlying eyelid or systemic issues.
• Culture or cytology in complicated or infected ulcers.
• Monitor healing progress with repeat staining every 1–7 days.

🛠 Medical Management

• Topical antibiotics: broad-spectrum drops/ointments—every 4–6 hrs for superficial; every 2–4 hrs for complicated ulcers.
• Pain control: topical atropine for ciliary spasm; NSAIDs systemic as needed.
• E-collar: essential to prevent self-trauma.
• Debridement: grid or punctate keratotomy for non-healing ulcers.

🔧 Surgical Interventions

• Conjunctival flap/autograft: covers deep/stromal ulcers or descemetoceles to aid healing.
• Corneal debridement: removes necrotic tissue supporting healing.
• Bandage contact lens: protects the ulcer and maintains the tear film.

📈 Prognosis & Follow‑Up

• Superficial ulcers typically heal in 5–7 days; deep or melting ulcers require ongoing monitoring and follow-up.
• Potential complications: scarring, neovascularization, uveitis, glaucoma, vision loss.
• Regular rechecks during treatment; adapt therapy based on healing pace.

🛡 Prevention & Owner Advice

• Prevent ocular trauma—avoid unsafe play and clear the eye area of sharp objects.
• Maintain eyelid health—treat entropion, distichiasis, and dry eyes early.
• Use artificial tears routinely in dogs predisposed to KCS or ocular dryness.
• Monitor high-risk dogs (e.g., Boxers, brachycephalics) closely after eye irritation.
