If you’ve ever looked at your horse and noticed one (or both) eyes suddenly looking blue, cloudy or milky, it can be alarming. This appearance is commonly referred to as a “blue eye”, and it usually indicates corneal oedema.
What is corneal oedema? | |
| The cornea is the clear outer surface of the eye. When it becomes irritated or injured, fluid can build up within it, causing a blue or hazy appearance. This change is not a diagnosis on its own, but a sign that something is wrong with the eye. |  |
What could cause a blue eye?
Corneal oedema can be associated with:
- Corneal ulcers (scratches or erosions on the eye surface)
- Trauma (from grass seeds, branches, rugs, or other horses)
- Inflammation inside the eye (uveitis)
- Increased pressure within the eye (glaucoma)
These conditions are painful and can progress rapidly if left untreated.
How urgent is it?
Eye conditions in horses are time sensitive. What may start as mild cloudiness can worsen quickly, potentially leading to permanent damage or even loss of the eye. Your horse should be seen by a vet THE SAME DAY.
What should I do if I notice it?
- Keep your horse in a low-light, dust-free area. A fly veil may be helpful.
- Do not apply any eye medications unless directed by your vet
- Contact us immediately to book a consultation.
A very important warning about eye medications
Never put Amacin or Prednefrin Forte into an eye without a veterinary consultation.
