Scientists have developed technology to assist in the diagnosis and management of dry eye disease.
The non-invasive optical imaging system uses a halogen light to illuminate the eye and then analyses the full spectrum of light reflection.
Writing in Applied Optics, scientists report that these spectral measurements provide insight into subtle changes in the tear film layers.
The Tear Film Imager, which can capture images in 40 seconds, has been used in two clinical studies in Israel and Canada.
Dr Yoel Arieli, from AdOM Advanced Optical Methods, highlighted that the device is risk free because it is non-invasive and uses a simple light source.
“It not only measured the tear film consistently including blinds every few seconds but the measurements correlated well with other partially invasive, established dry eye diagnostic techniques,” he shared.
