There is unceration (a gray film and a couple of white dots over the eyeball).
It likely started with getting something it the eye, scratching the eyball on something etc.
Two weeks of treatment so far and not much improvement. This could go on for months with me working to get meds into Willies eye and Willie working to keep me away from his eye.
The last one he had about 4 years ago did last months, but it wasn't as hard to medicate for some reason. There may come some talk of removing the eye. But that will include much contemplation over how well he will heal from surgery as he has cushings and therefore supressed immune system. And he is 28 years old.
This is what we're doing (me directed by the vet) Week one:
The pupil was constricted and that causes more pain. Also continued restriction of the pupil can lead to blindness. The vet used atrophine to open the pupil. Then Willie had to wear his flymask with ductape over the the right 1/2 of it to keep the sun out.
As you can see in week two list we had more trouble with the pupil. And then the worry over the chance that the atrophine would cause a colic episode! It didn't.
The gray film and Willie's pain level keeping the eye half closed, made it real hard to see what the pupil was doing! Then I discovered that the red light on my little LED headlamp looked right through the gray film!! And it didn't cause further Wincing from Willie.
We also added SMZ's to the mix on the second week: 20 twice a day.
This is what poor Willies feed bucket looked like twice a day:
From top to bottom:
Two little needless syringes, one with the 2 types of eye drops (#6,7 from above list) mixed together, the other with his own blood serum (#8) to fight any posible auto-immune response. (those are in the larger plastic capped tube to keep them clean)
Eye ointments (#3,4). Injectable pain med #1. Injectable pain med #2. The Ointment #5 on the list--never heard of vaginal antifungle being used in the eye. Just goes to show: You learn something new every day.
And the 20 SMZs in the oral syringe. Just visible sticking out from under the plastic bag is a small syringe containing the usual Cushing med (oral pergolide) which he only gets once a day.
Click here for information on preparing SMZs for the oral syringe.
In case you're interested: Willie eats Blue Seal Vintage Senior (ectruded feed with low sugars) and pelletted hay. He still gets free choice baled hay too. Even though he ends up having to spit out many of the mouthfulls he wads up in his old teeth and finds he cannot swallow, he still loves having it to work on. I know he still gets down a fair amount, and he has not yet choked, so I continue.
If you happen to notice the doses are sort of large, that's because Willie is sort of large, ~1800lbs
Willie is a boarder. He is a retired dressage school horse who's generous owner foots the board and all other bills for this old faithful worker.
Week three starts today. I don't have a new list just directions to repeat the week two list without the butorphanol (pain med #2)
