My mare had a minor eye injury the other day and we're lucky there was no corneal abrasion...probably just irritation under the lid. Vet prescribed atropine to dialate her pupil for 3 days, and triple antibiotic ointment for 5 days. Her pupil was still dialated yesterday morning (from the morning before) so I called the vet and they said to discontinue the atropine as it her eye was still dialated; they did not sound worried and I didn't think to ask if it was normal - they asked about tearing/discharge, cloudiness, swelling, all normal, so they said keep up the antibiotic ointment but otherwise sounded good. Today it's still somewhat dialated but otherwise looks fine. Is that just how atropine works? I understand it's purpose, just didn't realize two doses would have a long lasting effect. (Or perhaps because her injury is so minimal, it has a greater effect than a horse with more issues?) I will call again tomorrow if it's still dialated..... |

Got the answer from the vet today, in case anyone else ever experiences this. Yes, prolonged dialation is normal after atropine use, and the vet said she has seen cases where a horse's eye will stay dialated as long as a month after using atropine. (Hopefully that won't be my experience!) As long as that is the only prolonged symptom, the vet is not concerned; obviously keep a lookout for clouding, draining, swelling, squinting, etc. In the meantime it is important to keep a fly mask on your horse during the daytime while their eye is still somewhat dialated to protect it from the sun. Anyway....my mare's eye is looking good, just still about 1/2 dialated so I guess that's good news. |
