What are serum tears?

Some patients have very bad dry eye issues. Some patients have related issues caused by other diseases that affect the surface of the eyeballs.

One of the possible treatments for problems on the ocular surface is called “serum tears.”

What are serum tears? They are drops made out of the patient’s blood. No, really! The patient’s blood is placed in a centrifuge and, by spinning the blood, the heavy components of the blood move to the the bottom of the liquid. The “lighter” fluid on top is called the serum, and that’s the stuff that is used to make eye drops for the patient to use.

This may sound a little strange, but these serum tears really work quite well!
