What are the most common eye conditions that affect horses?
Horses, like humans, can suffer from a variety of eye conditions that may affect their vision and overall health. Understanding these common eye issues can help horse owners identify problems early and seek appropriate treatment. Common eye conditions in horses include conjunctivitis, corneal ulcers, and equine recurrent uveitis (ERU).
What is Conjunctivitis in Horses?
Conjunctivitis, often referred to as "pink eye," is an inflammation of the conjunctiva, the membrane covering the white part of the eye and the inner surface of the eyelids. This condition can be caused by infections, allergies, or irritants.
- Symptoms: Redness, swelling, discharge, and squinting.
- Treatment: Typically involves cleaning the eye and applying topical antibiotics or anti-inflammatory medications.
How Do Corneal Ulcers Affect Horses?
Corneal ulcers occur when the cornea, the clear outer layer of the eye, is damaged. These ulcers can result from trauma, foreign bodies, or infections.
- Symptoms: Cloudiness, excessive tearing, and sensitivity to light.
- Treatment: May include antibiotics, anti-fungal medications, or surgery in severe cases.
Understanding Equine Recurrent Uveitis (ERU)
Equine Recurrent Uveitis, also known as "moon blindness," is a serious inflammatory condition of the uveal tract, which includes the iris, ciliary body, and choroid.
- Symptoms: Pain, redness, and vision loss. Episodes may recur over time.
- Treatment: Often involves anti-inflammatory drugs and, in some cases, surgical intervention.
Other Eye Conditions in Horses
While conjunctivitis, corneal ulcers, and ERU are among the most common, horses can experience other eye issues:
- Cataracts: Clouding of the lens, leading to impaired vision.
- Glaucoma: Increased pressure within the eye, potentially causing vision loss.
- Squamous Cell Carcinoma: A type of cancer affecting the eyelids or conjunctiva.
How to Prevent Eye Conditions in Horses?
Preventing eye conditions involves regular care and observation:
- Regular Check-Ups: Schedule routine veterinary exams.
- Proper Hygiene: Clean the horse’s environment to minimize dust and debris.
- Protective Gear: Use fly masks to protect against insects and UV rays.

How can I tell if my horse has a corneal ulcer?
A horse with a corneal ulcer may exhibit excessive tearing, sensitivity to light, and a cloudy appearance in the affected eye. Prompt veterinary attention is essential to prevent complications.
Can equine recurrent uveitis be cured?
While there is no cure for equine recurrent uveitis, management strategies can reduce the frequency and severity of episodes. These include medications and, in some cases, surgical options like cyclosporine implants.
Are some horse breeds more prone to eye conditions?
Certain breeds, such as Appaloosas, are more susceptible to equine recurrent uveitis. Genetic factors and environmental influences can play a role in the prevalence of eye conditions.
What should I do if my horse has an eye injury?
If your horse has an eye injury, seek veterinary care immediately. Do not attempt to treat the injury yourself, as improper treatment can worsen the condition.
