Manatee eyes could be window to health status

o protect in areas that could otherwise be devastating."

Researchers speculate that tears, which can be collected without removing manatees from the water using a small, soft cotton swab, may one day be used along with or instead of blood tests to assess health status and to gauge whether the mammals were recently exposed to health threats such as red tide. Ongoing UF studies are exploring the relationship between the tear film and blood vessel formation.

"One of the findings of our earlier work was that there is absolutely no pathology involved in the formation of these manatee blood vessels, which in other species occur predominantly because of trauma or disease," Samuelson said. "So the question is, why do these mammals have such thick tears that corneal blood vessels form naturally, even in the fetus?"

Samuelson collaborated with Roger Reep, Ph.D., a UF professor of neurology, and Jenny Harper, Ph.D., a recent doctoral graduate who is now an assistant professor at Coastal Georgia Community College. Together they examined 26 eyes from 22 individual manatees and constructed 3-D images of the corneas.

"We've completed the evaluation and mapped the blood vessels, so we know where within the cornea they are located and how many there are," Samuelson said. "Our next goal is to start examining the tears and evaluate them with regard to the whole animal's health status."

He added that the recent study clearly documented the fact that these blood vessels are present, do not appear to interfere with manatee vision and appear to be a part of manatee anatomy beginning in the embryo.

"With that in mind, we are examining the tears to see what they exactly consist of, particularly with regard to the anti-infectious component," Samuelson said. "This may eventually be an opportunity to examine an individual manatee's state of health with regard to their immune system by analyzing their tears."
