It didn't improve at all, and she came back two weeks later. This time she did a keratectomy (used a needle to scratch a grid pattern onto ulcer). Again no improvement, but she said sometimes it took a couple times before it would heal. So she came back a week later and did it again. That was last Friday.
I've seen absolutely no improvement since then. She came out again today, and checked his eyelids thoroughly to see if there was something she was missing that could be scratching his eye, but she didn't see anything. She did cut off a little bit of tissue to look at it under a microscope.
He's been on banamine or bute since the first time the vet came out. We originally had him on bute for about a week, but his eye was still very painful so she decided banamine would be better. He's also been on atropine once a day as needed to keep his pupil dilated, and a few different antibiotics several times a day.
I'm just at a loss. My mom thinks I need to get a second opinion in case this vet is missing something. I do feel this vet is very competent, and she is with Wisconsin Equine clinic which I feel is a great vet clinic. I've always gone through them for anything I need.
Anybody gone through something similar or have any advice? Do I need to call another vet out?
