|Laser for Drusen - Trial Completed|
Complications of Age-Related Macular Degeneration Prevention Trial (CAPT). This multi-site trial, coordinated by the University of Pennsylvania used low-intensity laser to treat drusen in people with dry AMD. The study has been completed but participants are still being followed.
The hope was that applying laser to the drusen might be able to get rid of them and improve or preserve vision. In fact, the treatment did eliminate some of the drusen, but the vision gain was not large.
However, one arm of the study was terminated when a disturbing side effect occurred. Patients with wet AMD in one eye and dry AMD in the other were part of the study. When the laser was applied to the dry AMD eye, it seemed to trigger wet AMD in that eye. This did not occur to patients who had dry AMD in both eyes.
