Portable imager provides insight into eye and brain diseases

A handheld ophthalmology device with resolution-boosting adaptive optics technology has demonstrated the ability to image individual photoreceptors in the eye. The new portable instrument will allow improved diagnosis of eye diseases and could one day enable early detection of brain-related diseases and trauma.

“Until now, the imaging systems required for high-resolution photoreceptor imaging consisted of large, heavy components on an optical table that could only be used with cooperative adults sitting upright,” explains team leader Sina Farsiu from Duke University. “Our portable handheld system could expand this important imaging technique to children and infants, as well as to adults who may not be able to sit upright and stare straight ahead.”
