Researchers at Massachusetts Institute of Technology described a new handheld OCT that can quickly scan for diabetic retinopathy, glaucoma and macular degeneration—and improve public access to eye care.
The researchers say this design is the first to combine ultrahigh-speed 3-D imaging, a tiny micro-electro-mechanical systems (MEMS) mirror for scanning, and a technique to correct for unintentional movement by the patient. These innovations, the MIT researchers say, should allow clinicians to collect comprehensive data with just one measurement.
The investigators only studied retinal imaging, but they say this device could be modified for anterior segment imaging, too. It’s still a prototype, so no price has been determined yet.
