Corneal ulcers are among the most painful eye conditions dogs experience, requiring prompt diagnosis and treatment to prevent vision loss and relieve acute suffering.
Corneal ulcers cause acute, significant pain — the cornea is one of the most densely innervated tissues in the body. Dogs with untreated ulcers experience constant discomfort affecting sleep, eating, and behavior. Pain often leads to self-trauma, worsening the ulcer. Veterinary attention within 24 hours is essential; delays risk rapid progression from superficial to deep ulceration. Adequate analgesia during treatment is frequently underused in veterinary ophthalmology — topical anesthetics cannot be used long-term but systemic NSAIDs can reduce pain. Owner compliance with frequent medication schedules and E-collar use is the most common cause of treatment failure.
