I've had this mare for a little over a year. Her eye condition has been chronic, sometimes terrible sometimes not too bad. I've trailered her 6 hours to an animal eye doctor, who told me her eyelids were scarred and diagnosed "OU-conjuctivitis". The Dr prescribed "hyperosmotic for swelling". My vet has determined that the tear duct is NOT blocked. He has given me neoplybac ointment. Contacted the former owner who told me they used Prednisol on her. Some days she is pretty good, with just mild discharge. Some days she is terrible. Her fly mask will be soaking wet with discharge. I keep her face clean, use Systane or OpconA when it's not bad. If there is pus I use the eye ointment. If it's swollen I use the prednisol and sometimes banamine. The last couple of weeks have been terrible. I am at my wit's end what to do for her. I don't mind the daily care or buying the medicenes. But nothing seems to be working. My vet doesn't have any more ideas. It seems to be a mystery. I am wondering if I could suggest to him that she be on a round of antibiotic? I was not that impressed with the eye professional and won't subject my horse to that trailer ride again (anyone in the OKC area and considering an eye professional please PM me). I'm not going to trailer her to a bunch of different vets to be poked and tubed. I believe that the scarring of the eyelid must rub on the eyeball and cause the problem. But why is it terrible sometimes and not others? If this is an allergic episode, why doesn't the steroid help? She is the sweetest, gentlest horse; I feel so bad I can't seem to make her comfortable. The eye photo was taken this morning. The body picture of her was taken two weeks ago.
