Quantum imaging of the human eye


Our aim is to create a robust screening/early diagnosis device for Degenerative Eye diseases. It is the world’s first adoption of Quantum Laser Technology in Vision Sciences. This device is capable of performing macular tomography based on imaging and perception of structured light which helps assess the health of macula.

Problem addressed

Age-related Macular Degeneration (AMD) is a leading cause of irreversible blindness and visual impairment. Over 200 million people worldwide live with AMD. There are no current devices with normative data for early enough screening of AMD. Treatments like Photodynamic therapy, Anti-VEGF and AREDS 2 are available but not so effective for late stage AMD. Early diagnosis of AMD is essential.

  • Very first incorporation of structured light toolbox into vision science. The device uses Structured light with various Quantized Orbital Angular Momentum (OAM) states to test and quantify the entoptic perception ability of the patient which helps assesses health of the macula.
  • Imaging the retina using structured light allowing the assessment of the macular pigment density by characterizing the extent and resolution of entoptic perception.
Key impact
  • Early detection of macular degeneration (MD) is important to increase the effectiveness of currently avaliable treatments and slow down the progress of the damage to the eyes.
  • This Quantum structured light technology can be further developed to screen and diagnose other ocular diseases such as cataract, glaucoma, etc.
  • This technology can help creating a screening culture for general eye health. Incoporate this screening technology into regular medical check ups, especially for older adults.
  • Device in General Practitioners Clinics, Optometry clinics, hospitals for regular screening of ocular health
  • Device at elderdy homes and NGOs to screen paitents with higher risk of AMD
  • Approved US patent: Preparing a Structured Optical Beam for Human Observation (US11564562B2)

The Centre for Eye and Vision Research (CEVR)  is a research collaboration between The Hong Kong Polytechnic University and the University of Waterloo in Canada under the InnoHK initiative of the HKSAR Government. It is located at the Hong Kong Science Park, Shatin, Hong Kong. It is the first global hub performing ground-breaking research in five key areas Myopia and Eye Growth, Ocular Drug Discovery and Delivery, Vision Enhancement, Tear Film and Ocular Surface, and Advanced Optometric Technology. The mission of CEVR is to generate technologies to prevent vision loss in the aging population and preserve healthy vision.
