*** EYES ARE ALWAYS EMERGENCIES - Saturday night quiz answer! ***
Thank you to the hundreds of you that took part in the eye quiz! I was of course called straight out to look at this lovely cob’s swollen eye, and obviously calling the vet out that day was the correct answer.
Horses only have two eyes, and when eyes start going wrong, they can spiral downhill rapidly; immediate, CORRECT, treatment of any eye issues is essential. Never mess around trying to treat an eye without vet involvement.
Of course, horses can get “puffy” eyes for fairly innocuous reasons - flies/wind/allergies. They may also get conjunctivitis, which will more often than not affect both eyes. My absolute rule of thumb is to ALWAYS visit a horse the same day if only ONE eye is affected; you’d be extremely unlucky to get ulcers in both eyes, but any swelling or pain in just ONE eye is absolutely not a next day visit.
It is essential to diagnose the cause of the painful eye, as treatment will depend on what the pathology is. Putting steroid drops, or any drops containing steroids (Maxitrol) into an eye with an ulcer, will make the ulcer a lot worse and may well result in the loss of the eye, as just one example. Eyes with a miotic pupil (very constricted pupil that cannot dilate) will not only be extremely painful, but will also need treating immediately with drugs to artificially open the pupil and thus try to avoid permanent damage to the eye, as a second example.
This cob’s eye nearly caught me out, and shows why the vet must stain a painful eye, and examine every millimetre of the cornea; there is a small ulcer right at the bottom of the eye (see the green stained circle). He was immediately started on the correct drops, and I expect the ulcer to heal rapidly. His eye was just slightly swollen and watery, but shows the absolute importance of immediate veterinary involvement for eyes, especially when just one eye is affected.
Feel free to share, and thanks for the great audience participation last night!
