Research Programmes

  1. Development and application of image analysis techniques for studying eye diseases including diabetic retinopathy, diabetic macular edema and glaucoma.
  2. Identification of new imaging subclinical makers for predicting diabetic retinopathy progression.
  3. The role of vascular imaging markers in normal tension glaucoma.
  4. Development of risk prediction algorithms based on imaging measures for stratifying patients into different risk categories.
  5. Retinal ganglion cell and microvascular network imaging in Alzheimer’s disease.
  6. Linking age-related eye disease and Alzheimer’s disease.

Results of Note

  1. Developed and validated different methods to quantify retinal vasculature and capillary network.
  2. Showed that retinal vascular assessment can provide additional prognostic information on retinopathy risk prediction in persons with diabetes.
  3. Demonstrated retinal imaging is a promising tool to study brain diseases including Alzheimer’s disease and stroke.
  4. Received competitive research grant funding from HKSAR Food and Health Bureau, titled “Novel Retinal Imaging Biomarkers for Cognitive Decline”.
