Researchers at the University of Waterloo have created a non-contact laser imaging system that detects symptoms of eye diseases that cause blindness and that are usually not diagnosed until the vision loss is irreversible.
Currently, eye diseases such as age-related macular degeneration, diabetic retinopathy and glaucoma have no symptoms in their early stages. Diagnosis is typically only made once vision has been affected.
The new technology provides functional details of the eye including oxygen saturation and oxygen metabolism. Multi-colored lasers are able to almost instantly image human tissue without ever touching it. This new technology is called Photoacoustic Remote Sensing (PARS).
For now, we recommend regular eye examinations with your ophthalmologist or optometrist.
