Equine recurrent eyeitis (ERU), a condition that causes inflammation of the eyes in horses, can cause blindness, pain, and damage. This is often caused by an immune reaction in the horse’s system, which can be triggered by an infection. Preventing ERU in horses is crucial to keep them safe and healthy. There are steps that owners can take to prevent or treat ERU in horses.
What is Equine Recurrent Uveitis (ERU)?
Equine recurrent eyeitis (equine uveitis) is an inflammation of middle layer of the eyes called the uvea. It is the leading cause of blindness in horses, and the most common cause for eye disease in horses. The iris, the ciliary body and the choroid make up the uvea. These three components of the eye control the amount of light entering the eye, regulate the size of the pupil and provide nutrition. The uvea can become inflamed and cause various symptoms, which can be mild or severe. This can cause redness, swelling, light sensitivity, cloudiness, and watery eyes. Horses can also experience vision impairment and blindness, as well as pain.
ERU can be caused by many things, but the main cause is the body’s immune response. Equine herpes virus or strangles are common causes of the immune response. ERU can also be caused by eye trauma, toxins, or genetics.
ERU treatment aims to reduce inflammation and pain, prevent further damage to your eye and preserve vision. Anti-inflammatory medication and drops are used to treat ERU. Surgery may be required depending on the severity and type of the condition.
Non-steroidal anti-inflammatory drug (NSAIDs) are the most commonly used medications to treat ERU. These medications can reduce inflammation and pain and help prevent eye damage. Corticosteroids and antifungal medication, as well as antibiotics, may also be used.
Surgery may be required in severe cases of ERU to fix the eye and prevent further damage. The surgery may include removing scar tissue, replacing the eye, and/or repairing it. A veterinary ophthalmologist is a specialist in the treatment of eye diseases in animals and is typically responsible for performing surgery.
Preventing the ERU
ERU can be prevented by taking steps to ensure that the horse’s environment is free from potential triggers such as infections or toxins. You must provide clean water and food for your horse, as well as adequate ventilation and avoid overcrowding. ERU can be prevented by vaccinations, which reduce the chance of infection.
What is the most frequent cause of ERUs?
ERU can be caused by an immune response, which is usually triggered when there is an infection or virus.
What drugs are used to treat ERU
Non-steroidal anti-inflammatory drug (NSAIDs) are the most commonly used medications to treat ERU. Corticosteroids and antifungal medication are also options.
Recurrent uveitis in horses is a potentially fatal and painful condition. The goal of treatment is to reduce inflammation and pain, prevent further damage to the eyes, and preserve vision. ERU can be prevented by taking steps to ensure that the horse’s environment is free from potential triggers such as infections or toxins. The risk of infection can be reduced by vaccinations. These steps can be taken by owners to ensure their horses are safe and healthy. See the following for more information.
