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.
