LEDs illuminate eye for ocular disease screening
( American Institute of Physics ) A new imaging system using six different wavelengths to illuminate the interior of the eyeball (ocular fundus) may pave the way for doctors to easily screen patients for common diseases of the eye, such as age-related macular degeneration and diabetic retinopathy. The system is described in the journal Review of Scientific Instruments. Continue reading
