Touchless technology could enable early detection, treatment of eye diseases that cause blindness

OT Staff Reports, David Hutton

According to investigators, the new technology is designed to detect telltale signs of major blinding diseases in retinal blood and tissue that typically go unseen until it is too late.

According to investigators, the new technology is designed to detect telltale signs of major blinding diseases in retinal blood and tissue that typically go unseen until it is too late.

Investigators believe a non-contact laser imaging system could help doctors diagnose and treat eye diseases that cause blindness much earlier than is now possible.

The new technology,1 developed by engineering investigators at the University of Waterloo in Waterloo, Ontario, Canada, is designed to detect telltale signs of major blinding diseases in retinal blood and tissue that typically go unseen until it is too late.

With current testing methods, diseases such as age-related macular degeneration, diabetic retinopathy and glaucoma, which have no symptoms in their early stages, are usually diagnosed only after vision is irreversibly affected.

“We are optimistic that our technology, by providing functional details of the eye such as oxygen saturation and oxygen metabolism, may be able to play a critical role in early diagnosis and management of these blinding diseases,” said Parsin Haji Reza, director of the PhotoMedicine Labs at Waterloo University, in a statement.

According to investigators, patented technology at the core of the new system is known as photoacoustic remote sensing (PARS). It uses multicolored lasers to almost instantly image human tissue without touching it…..
