Eye redness in horses can often signal underlying health issues that may threaten their vision. Identifying the cause early is essential for proper treatment and care. Here’s a concise guide on how to assess your horse’s eye health and recognize warning signs that require immediate attention.
- Eye redness in horses is a common symptom that can be linked to serious conditions.
- Issues like corneal ulcers and uveitis may negatively impact your horse’s vision.
- Immediate emergency medical attention is crucial for preserving vision.
- Assess your horse’s eye carefully—always compare its appearance to the other eye.
- Watch for other signs of eye injury, such as watering or grayness on the clear corneal surface.
- If these signs are present, the problem could be directly related to the eye itself.
- Use the Whole Horse Exam (WHE) to check the opposite eye, observe their attitude, appetite, and measure rectal temperature, heart rate, and gum color.
- If any abnormalities are detected, contact your vet to discuss your findings and concerns.
Keeping your horse healthy overall is important when dealing with specific issues like red eye. For example, knowing how long horses live can help you manage their health as they age. Regular exercise and understanding how far and for how long a horse can run can also prevent stress that may affect their eyes. Additionally, simple care routines, like restoring their coat after winter, can help keep them in good overall condition.
Eye Redness in Horses: Symptoms & Causes
Here’s a concise table outlining symptoms and causes of eye redness in horses:
| Symptoms | Possible Causes |
| Eye redness | Corneal ulcers, uveitis |
| Watering of the eye | Eye injury, irritation |
| Grayness on corneal surface | Corneal ulcers, inflammation |
| Swelling around the eye | Infection, trauma |
| Sensitivity to light (squinting) | Uveitis, eye injury |
| Discharge from the eye | Bacterial or viral infection |
| Cloudiness in the eye | Corneal ulcers, uveitis |
| Decreased appetite or lethargy | General discomfort or pain |
Risk Factors for Eye Redness in Horses
Conjunctivitis and Inflammation
Eye redness often results from conjunctivitis, causing swelling and irritation of the pink tissue around the eye. This can be triggered by environmental factors like dust, allergens, or bacterial infections.
Traumatic Eye Injury
Physical trauma to the eye can lead to redness, especially if caused by scratches, debris, or foreign bodies. Injuries can also result in further complications like corneal ulcers.
Scleral Reddening
Redness in the white part of the eye (sclera) can indicate deeper health issues such as endotoxemia or other serious infections like gastrointestinal diseases. These infections allow bacteria to enter the bloodstream and affect the eye.
Hyphema
Hyphema refers to the presence of blood in the front chamber of the eye, often caused by trauma, blood clotting disorders, or severe injury. This condition needs immediate veterinary care to prevent lasting vision damage.
Corneal Ulcers
Ulcers on the cornea are a common cause of redness, often resulting from injury, infection, or foreign objects in the eye. Corneal ulcers can lead to severe pain, excessive tearing, and potential vision loss if untreated.
Uveitis
Uveitis is a serious inflammatory condition that can affect the horse’s vision. It is characterized by redness, swelling, and sensitivity to light, often requiring long-term treatment to manage flare-ups.
Foreign Bodies
Foreign objects like dust, hay, or small particles can irritate the eye, leading to inflammation and redness. If not removed promptly, this can cause further complications like infection or ulcers.
By understanding these risk factors, owners can monitor their horse’s eye health closely and seek timely treatment.
What Should You Do If Your Horse Has Eye Redness?
- Compare both eyes: Look for differences in appearance, including watering, swelling, or grayness on the clear corneal surface.
- Assess the eye: If any of these signs are present, the issue is likely related to the eye itself.
- Conduct a Whole Horse Exam (WHE): Check the opposite eye, attitude, appetite, rectal temperature, heart rate, and gum color to evaluate overall health.
- Contact your vet: If you notice unusual signs, reach out to your vet immediately for guidance to prevent complications and preserve your horse’s vision.

Testing and Diagnosis for Eye Redness in Horses
When a horse shows signs of eye redness, it’s important to get an accurate diagnosis to determine the cause and decide on the best treatment plan. Here’s a breakdown of the common tests and diagnostic procedures that veterinarians use to identify the issue:
- Physical Examination: A thorough check of the horse’s overall health, focusing on the eyes and any visible signs of injury or infection.
- Ophthalmic Examination: A specialized examination of the horse’s eye, using tools to look closely at the eye’s structure and any abnormalities.
- Tear Production Testing: This test measures the amount of tears the horse produces, which helps detect dry eye conditions or underlying infections.
- Fluorescein Staining: A dye is applied to the eye to highlight any ulcers or damage to the cornea, making it easier to detect small scratches or injuries.
- Intraocular Pressure (IOP) Tests: This measures the pressure inside the eye to check for conditions like glaucoma or other diseases affecting eye pressure.
- Cytology: A sample from the eye is taken and examined under a microscope to look for signs of bacterial, viral, or fungal infection.
- Biopsy: In some cases, a small sample of tissue is taken from the eye for further examination to diagnose more complex conditions.
Common Treatments
Treatment depends on the underlying condition. Typical approaches include:
- Antibiotics: Used to treat bacterial infections.
- Anti-inflammatory Medications: To reduce swelling and inflammation in the eye.
- Pain Management: Providing relief from discomfort with pain control medications.
- Surgery: In severe cases, the eye may need to be surgically removed to prevent further complications.
By conducting these tests early, your veterinarian can create a proper treatment plan and help preserve your horse’s vision.
Associated Symptoms
Eye redness often comes with other symptoms that may help in diagnosing the issue. These include:
- Loss or decreased appetite (anorexia)
- Lethargy
- Eye discharge
- Excessive blinking or squinting
- Cloudy appearance in the eye (corneal edema)
Early diagnosis and prompt treatment are vital to addressing eye redness and related conditions. Make sure to consult your vet if any of these symptoms appear.
