New Device for Detecting Eye Diseases

Optical Coherence Tomography
Optical coherence tomography is a technology that bends infrared light in examining eyes for such things as glaucoma and macular degeneration. The machines that do this are table-top size, but researchers at MIT have used MEMS techniques to make a mirror which is the heart of a hand held version that measures IR “light echoes.” The result is visualization of the retina’s tissue structure. At this stage, the device remains at the prototype level awaiting further research to reduce the machine’s cost. MORE
