Large Study Evaluates Laser Treatment for AMD Vision Loss

According to a study that appears in the November 2006 issue of the journal Ophthalmology, researchers at the University of Pennsylvania School of Medicine and 21 other clinical centers have found that low-intensity laser treatment - thought to be potentially beneficial in slowing or preventing the loss of vision from age-related macular degeneration (AMD) - is ineffective in preventing complications of AMD or vision loss.

New Laser-Based Technique Provides First Non-Invasive Test to Measure Skin Aging

Physicists and medical researchers for the first time have demonstrated a new technique that non-invasively measures in real time the level of damage to the skin from sun exposure and aging, and initial results suggest that women's skin ages faster than men's.
