So for as long as I've had my mare she's had this funny eye twitchy thing. It'll happen fairly often, about once or so an hour - with no known trigger. It happens when she's eating, being groomed, standing around, working anything. I've finally managed to get a stupid picture of it. I asked my vet she said 'it must be a deficiency or something' but because it's not life threatening didn't care to look further into the matter. She said 'sometimes horses just have quirks'. But if it is a deficiency or a muscle problem I really would like to fix that. For all I know the outward eye twitch could be the tip of an iceburg. Has anyone heard/seen/dealt with this sort of thing before?
I guess the only other thing to mention is she has a serious reaction to bugs, she rubs her neck and belly bald, despite how much I soak her in fly spray, she's got ripples all down her belly - I was told from collagen breakdown from twitching it so much. I don't know if those two issues are related.
Here's the pic of her eye:
Essentially her bottom eyelid will suddenly droop down, where it's all red and gooey, and it'll twitch for a little bit, then the top eyelid will droop - then she'll blink and her eye will be normal again. It's more dramatic than what the picture shows, I think that was right as she was about to blink.
