A link to this article was posted on a zoo forum.

Unfortunately you can only access the summary of the journal article but it is interesting nonetheless.

"Whether the snakes actively reduce blood flow in the eye or do so as a side effect of sympathetic response induced by a threat, van Dorn doesn't know." According to one source, further study will be looking into the mechanisms behind it.

Sorry just saw that this topic has already been posted by News Bot some time ago. The information in the article covers much from my links but there are some extra details in the above links.
