If you have a high school reunion coming up, here's a medical development that you may want to keep an eye on.

Federal regulators for the first time have approved Botox injections to treat crow's feet.

The Food and Drug Administration said Wednesday that Allergan's Botox Cosmetic injection is the first drug approved to treat the wrinkles that form on the outside edge of the eyes.

Allergan Inc. studied use of the drug in 833 adults with crow's feet who randomly received Botox or a sham injection.  Patients who received Botox had fewer visible wrinkles than those who received the placebo drug.

The most common side effects seen in patients were swelling and excess liquid around the eyelids.
