Biography

Dr Cheung’s main research interest is “imaging of the eye”, based on the concept that the eyes are the “window” to the human circulation and nervous systems. She has been working in the field of ocular imaging for more than 15 years in Hong Kong and in Singapore, focus on development and application of image analysis techniques and artificial intelligence for studying diabetic retinal disease, glaucoma and Alzheimer’s disease. She is now focused on translating her artificial intelligence-related research from “concept” to “implementation”, with an aim to enhance eye disease screening in primary care, and eye disease triaging in tertiary clinics, for timely eye disease management and treatment. This will bring significant societal impact by improving quality and efficiency of the clinical service in Hong Kong and beyond the region. Dr Cheung has authored more than 250 original research articles, 9 commentary or editorial articles and 27 review articles in SCI international indexed peer reviewed journals, and 14 book chapters. She has published several landmark papers on development of AI-based technologies in ocular imaging for detection of multiple eye diseases, and quantitative analysis for assessing diabetic microvascular diseases from optical coherence tomography angiography, with an H-index of 55 and citations >10,200 (Scopus, Jan 2022).

Research Areas

Using ocular imaging technology and artificial intelligence to study human circulation and nervous systems, and link with eye, brain and cardiovascular diseases, in particular, diabetic eye disease, glaucoma, Alzheimer’s disease and stroke.

Research Highlights

Research Programmes

  1. Studying the human microcirculation via the retinal and choroidal vessels using state-of-the-art ocular imaging technologies
  2. Studying the central nervous system via the optic nerve and retinal neuronal and axonal layers using state-of-the-art ocular imaging technologies
  3. Development and application of image analysis techniques and artificial intelligence (AI) for eye disease detection and prognosis.
  4. Implementation of AI algorithms in primary care and tertiary care settings to support eye disease screening, triaging and referral pathway for timely eye disease treatment and management.
  5. Identification of new imaging makers for predicting diabetic retinal disease and its progression.
  6. Identification of vascular imaging markers in normal tension glaucoma.
  7. Understanding of the epidemiology, systemic associations and clinical implications of hypertensive eye disease.
  8. Using retinal imaging to study Alzheimer’s disease.
  9. Linking age-related eye disease (e.g. glaucoma) and Alzheimer’s disease.

Results of Note

  1. Developed and validated AI-based algorithms for eye disease classification.
  2. Developed and validated different methods to quantify retinal vasculature and capillary network.
  3. Showed that retinal vascular assessment can provide additional prognostic information on retinopathy risk prediction in persons with diabetes.
  4. Demonstrated retinal imaging is a promising tool to study brain diseases including Alzheimer’s disease and stroke.
  5. Received competitive research grant funding from General Research Fund (GRF), HKSAR Food and Health Bureau, and BrightFocus Foundation.
