Scientists can now produce a full 3D image of the entire retina to diagnose and treat eye diseases such as cataracts, diabetic retinopathy, and cancer, thanks to a new laser-based technique.
Medics will now be able to take an image of the eye ten times faster and over ten times longer range than ever before, dramatically improving their ability to assess the condition of the eye and to ensure that nothing is overlooked.
Early diagnosis and follow-up treatments are necessary to prevent eye diseases from turning into blindness. However, early diagnosis is limited by the ability to make full 3D images of the eye. Eye specialists currently use a non-invasive imaging technique called OCT but, because the eye is continuously moving, it can only make partial images.
Until now, this technology hasn’t been fast enough to take a full image of the eye.
Researchers from the Technical University of Denmark (DTU) have developed a swept light source technology that makes it possible to take full 3D OCT images of the eye and this innovative technology is being commercialised by the university spin-out company OCTLIGHT ApS.
