We are seeing an exceptionally large increase in the number of horses with eye problems. These problems are including eye ulcers, uveitis, trauma to the eye and conjunctivitis.
Causes
- Some of these problems are related to flies, causing infection.
- The bright sunlight that we are currently getting is causing the sensitive areas of the eye to become inflamed and painful in some horses
- In many areas there is now little grass on some fields due to the lack of rain and therefore some horses are rooting in hedges, where they wouldn’t normally be and scratching their corneas
What to look for:
- Discharge from eyes (can be watery or cheese like)
- Red eyes or conjunctiva
- Closed or partially closed eyes
- Excessive blinking with the affected eye
- Sensitive to bright light
- Swollen eye lids

How to help your horse
- Turning your horse out in a full fly mask with UV protection is the best way to avoid eye problems.
- Where possible, avoid turning your horse out in the bright sunlight, unless it has a mask on.
- Avoid riding at the brightest, hottest part of the day
- Observe your horse’s eyes daily
