Understanding the most common eye diseases in horses is essential for horse owners and equine caretakers to ensure the health and well-being of these animals. Early detection and treatment are crucial in managing these conditions and preventing long-term damage or vision loss.
What Are the Most Common Eye Diseases in Horses?
Horses are susceptible to several eye diseases, with equine recurrent uveitis, corneal ulcers, and conjunctivitis being the most prevalent. Recognizing the symptoms and seeking veterinary care promptly can help mitigate these conditions.
Equine Recurrent Uveitis (ERU)
Equine recurrent uveitis is the leading cause of blindness in horses. Also known as moon blindness, it is an inflammatory condition of the eye’s uveal tract.
- Symptoms: Redness, tearing, squinting, and sensitivity to light.
- Causes: Often linked to infections, immune-mediated responses, or trauma.
- Treatment: Involves anti-inflammatory medications and, in severe cases, surgical intervention.
Corneal Ulcers
Corneal ulcers occur when the outer layer of the cornea is damaged, often due to trauma or foreign bodies.
- Symptoms: Cloudiness, tearing, and visible defects on the cornea.
- Causes: Injury, infections, or foreign objects.
- Treatment: Antibiotic drops, anti-inflammatory medications, and protective eye coverings.
Conjunctivitis
Conjunctivitis is an inflammation of the conjunctiva, the membrane covering the white part of the eye and inner eyelids.
- Symptoms: Redness, discharge, and swelling.
- Causes: Allergies, infections, or irritants like dust.
- Treatment: Depends on the cause but may include antibiotics or anti-allergy medications.
Cataracts
Cataracts in horses involve the clouding of the eye’s lens, leading to impaired vision.
- Symptoms: Cloudy or opaque lens, decreased vision.
- Causes: Congenital defects, trauma, or secondary to other eye diseases.
- Treatment: Surgical removal is the most effective option for significant vision impairment.
Glaucoma
Glaucoma occurs when there is increased pressure within the eye, potentially leading to optic nerve damage.
- Symptoms: Pain, redness, and vision loss.
- Causes: Often secondary to other eye conditions like ERU.
- Treatment: Medications to lower intraocular pressure or surgical procedures.
How to Prevent Eye Diseases in Horses
Preventive care is key to maintaining your horse’s eye health. Here are some tips:
- Regular Check-ups: Schedule routine veterinary exams to catch issues early.
- Protective Gear: Use fly masks to reduce exposure to irritants and prevent injuries.
- Clean Environment: Maintain a clean living area to limit exposure to dust and debris.
- Prompt Treatment: Address any signs of eye issues immediately to prevent complications.

What Causes Eye Infections in Horses?
Eye infections in horses are typically caused by bacteria, viruses, fungi, or irritants like dust and pollen. Prompt veterinary attention is crucial to identify the cause and administer appropriate treatment.
Can Horses Recover from Eye Diseases?
Yes, with early detection and proper treatment, many horses can recover from eye diseases. However, conditions like ERU may require ongoing management to prevent recurrence.
How Can I Tell If My Horse Has an Eye Problem?
Signs of eye problems in horses include redness, swelling, discharge, squinting, and sensitivity to light. If you notice these symptoms, consult a veterinarian promptly.
Are Certain Breeds More Prone to Eye Diseases?
Some breeds, like Appaloosas, are more prone to conditions like ERU due to genetic predispositions. Regular monitoring is recommended for breeds with known susceptibility.
What Is the Cost of Treating Eye Diseases in Horses?
The cost varies depending on the condition and treatment required. Routine treatments may be affordable, but surgical interventions can be more expensive. Consult your vet for specific estimates.
