She said that 2 other horses there did that and it ended up being a vitamin E deficiency, from reading I think she was talking about EMND. She said she treated with vitamin E and they returned to normal. The vet told her it is pretty common around here(PA) since our soil doesn't have a high vitamin e content so they don't get enough from grass and hay.

Looking at her grain alone, triple crown senior(6.5lbs/day) she is only getting 1,105 IU's, She gets 6-9lbs(can't remember if she gets 1 or 1.5 scoops a feeding) of alfalfa pellets a day also, I can't seem to find if there is vitamin E in alfalfa tho. She also gets grass hay, but from what the vet told my barn owner, that isn't going to have much vitamin E in it.

I read that they should get minimum of 2,000 IU's per day. So should I add some vitamin E to her diet? My barn owner also said not to get one with Selenium. Does anyone know the max Selenium they should have in their diet?
Are you sure you didn't mis-hear her. And that she didn't say Vitamin A?

Vitamin A deficiency signs are night blindness and corneal cloudiness.

Vitamin E deficiency signs are decreased serum tocopherol, increased red blood cell fragility, muscular dystrophy.

There's ordinarily sufficient vitamin A and e in alfalfa

Vitamin E has an interdependency for selenium. It requires selenium to work efficiently. Most often rather than the diet being deficient in vitamin E, it's deficient in selenium and that's something that does vary with geographical locality.

If you're feeding aged hay then vitamin E levels will deplete but I'm wondering anyway with the problem being vision if you've got this wrong and it's vitamin A they're talking about.
