By combining traditional eye imaging techniques with adaptive optics - a technology that enhances imaging resolution - researchers at the National Eye Institute have shown for the first time how cells across different tissue layers in the eye are affected in people with choroideremia, a rare genetic disorder that leads to blindness.
Using a new imaging technique, researchers from the National Eye Institute have determined that retinal lesions from vitelliform macular dystrophy (VMD) vary by gene mutation.

Published in Optica, the researchers report how they improved imaging resolution by a third by selectively blocking the light used to image the eye. NEI is part of the National Institutes of Health.
