The whites of the eyes is called the sclera. It's really interesting because according to the article below, it's actually the most visible in humans than any other animal. I also agree with LC, most mammals have a white sclera. If you happen to see yellow, then it's indicative of jaundice (due to liver or gall bladder issues).
I also echo Librarychick. The most nervous horse I ever dealt with would have white right around his eyes except in his total comfort zone but it was a total indicator of where he was on his comfort scale.
