myPET Podcast: The Eye Of The Horse!

This episode explores eye problems in horses — why they happen so often, the conditions that commonly affect the equine eye, and why urgent veterinary assessment is essential. It explains conjunctivitis, corneal ulcers, fungal keratitis, stromal abscesses, uveitis, eyelid injuries, tumours, congenital lid issues in foals, and how easily minor eye problems can become serious without prompt treatment.

Podcast Summary: Understanding Eye Problems in Horses

  • Horses have the largest eye of any land mammal, making them prone to trauma, ulcers, and environmental irritation.
  • Any sign of soreness — blinking, rubbing, discharge, swelling, cloudiness, or light sensitivity — requires prompt veterinary assessment.
  • Conjunctivitis is common in dry, dusty, fly-heavy conditions and usually presents with red, irritated tissues and pus-like discharge.
  • Corneal ulcers occur from trauma, dust, grass seeds, or infection; they are extremely painful and can deteriorate rapidly without treatment.
  • Fungal keratitis and stromal abscesses are serious complications where infection becomes trapped within corneal layers, often requiring intensive treatment.
  • Fluorescein staining helps diagnose ulcers by highlighting damaged corneal layers.
  • Topical cortisone should never be used unless specifically prescribed — it can worsen ulcers and cause catastrophic damage in horses.
  • Treatment often requires sedation, nerve blocks, topical medications, and sometimes palpebral lavage systems to deliver frequent eye drops safely.
  • Uveitis is a common, painful inflammatory condition that can become recurrent and lead to blindness or eye removal if unmanaged.
  • Sarcoids, squamous cell carcinomas, and other tumours may occur on eyelids or surrounding skin, especially in horses with unpigmented skin.
  • Foals may develop entropion (inward-rolling eyelids) causing lashes to rub the eye; early correction prevents ulcers and long-term damage.
  • Eyelid lacerations, blunt trauma, and puncture wounds are common due to the horse’s prominent eye position and natural behaviours.
  • Cataracts and age-related cloudiness occur in older horses, but many adapt well to gradual vision loss.
  • Rapid-onset blindness causes more distress than slowly progressing disease; horses often adapt if changes are gradual and they have a paddock companion.
