Using less light is an advantage. view more  Credit: Johnny Tam, National Eye Institute WASHINGTON Researchers have developed a noninvasive technique that can capture images of rod and cone photoreceptors with unprecedented detail. The advance could lead to new treatments and earlier detection for retinal diseases such as macular degeneration, a leading cause of vision loss. We are hopeful that this technique will better reveal subtle changes in the size, shape and distribution of rod and cone photoreceptors in diseases that affect the retina, said research team leader Johnny Tam from the National Eye Institute. Figuring out what happens to these cells before they are lost is an important step toward developing earlier interventions to treat and prevent blindness.
