Sorry it took so long to respond, I just got back from a friends. Her horse was showing signs of colic.
The injury T had looked like something had poked her in the eye and it ulcerated. From that , from what I understand, she developed uveitus. We had to do a combination of atropine to open the pupil, and then an antibiotic ointment. The atropine was applied 3 - 4 x's the first day along with the ointment, and then just the ointment 3-4 x's a day for 2 weeks. With this was a regiment of buffered aspirin to aid in the reduction of inflammation.
Since then, we've had a few recurrences per year, with last year having only one. I know the routine, and have a great working relationship with the vet, so treat it myself with phone support from the vet. Building up her immune system became a priority, as she is over 20 and the immune system "weakens". Can only hope that this continues to help in preventing any more recurrences.
The Guardian mask is pricey, but is very well made and has held up for us now for 5 years. She can't rub her eyes with it like a typical mask, so she can't further irritate her eye, especially during a recurrence.
I'm sure your horse will be fine, and good for you for calling your vet asap. Eyes are not something to wait and see imo. My girl has lost sight in her right eye, and now has limited vision in the left due to cataracts. But so far she is adjusting well and is still taken on the trails.
So I'm actually a big fan of catheters for eye injuries because getting those **** meds in there is so hard sometimes (especially when the eye really hurts or is extremely swollen).
We had a pony at the barn who had debris blown into her eye and she rubbed the snot out of it before anyone noticed her eye was swollen shut, the abrasion on her cornea was probably almost the size of a dime and she had some cloudiness.
She had to get LOTS of meds in her eye, including something made from her own blood (I was not exactly paying attention to the vet, I was playing gofer and getting everything everyone needed to make that pony comfortable, so I don't know what it was from her own blood).
Anyways, the point is, no struggle to get the meds in (yes she was not very please when she felt the meds go in, but you always KNEW they got in her eye 100% without poking her eye or fighting with her). It helped with a quick recovery, although she was confined to a stall.
A fly mask would be extremely bneficial, to prevent rubbing as well as possibly getting other irritants in it.
Okay here's an update... unfortunately not a good one D:
I had to work later than I planned today so I went to the barn RIGHT after, so I wasn't able to get my camera, but I will try to get pictures tonight or tomorrow.
Anyway, I get to the barn and run to his stall HOPING to see better results than yesterday and he isn't even opening his eye anymore. When he did squint it open (was never open more than 50% even when he was looking at something, yesterday it COULD open all the way but he kept it at about 50% resting) it was a yellowish cloudy color and the area he cut it was white.
I called the vet and he said he was on a call right now but he would come by and look at it this afternoon.
I'm going to be getting medicine in his eye at all times of the day now. I work morning unfortunately (6 AM so it's really really hard to get out before then), but I'm going to try to get my mom/brother to be able to put it in his eye (right now he's a fighter with it, doesn't want anyone touching that eye) for the morning at least, and then on my lunchbreak I'm just going to have to drive straight to the barn give medicine and drive straight back, and then right back out after work.
I just want my pony better seeing his eye SO bad today dropped any good feelings I had about his recovery.
