Mr Victor T.T. CHAN, our year-4 MBChB-GPS student supervised by our faculty Dr Carol Cheung, was invited by the Journal of Visualized Experiments (JoVE) to introduce the application of retinal imaging in dementia research.
The retina offers a unique “window” to study dementia in the brain, as it is an anatomical and physiological extension of the central nervous system and shares prominent similarities with the brain in terms of vascular and neuronal structure. The vascular and neuronal structure in the retina can now be visualized non-invasively using widely available retinal imaging techniques, including fundus photography and optical coherence tomography (OCT). Studying the association between vascular and neuronal changes in the retina and dementia could improve our understanding of dementia and, potentially, aid in diagnosis and risk assessment. During the interview, Victor and our team introduced the retinal imaging methods and the potential of retinal imaging in studying dementia. The interview and the procedures of retinal imaging will be published as a peer-reviewed video article (Chan VT, Tso TH, Tang FY, Tham CC, Mok V, Chen C, Wong TY, Cheung CY. Using Retinal Imaging to Study Dementia. J Vis Exp. [2017 in press]).
Global Physician-Leadership Stream (GPS) is the CUHK Faculty of Medicine’s flagship undergraduate educational platform launched in 2013, aiming to nurturing students to become future physician leaders in the medical field. Under the support of GPS, students with excellent academic ability and passion in conducting medical research are provided with additional research opportunities, leadership training and personal mentoring. Being one of the most outstanding students in GPS, Victor is now conducting a clinical study in our department under Dr Carol Cheung’s supervision and mentorship to investigate the associations between retinal changes and dementia, aiming to translate and apply the retinal imaging as a potential non-invasive biomarker for identifying who are at higher risk for dementia.
