Population Health Research Group


Overview

The Population Health Research Group is the translational eye research unit at SERI. Led by Professor Ecosse Lamoureux, the unit is focused on the epidemiology and risk factors of major eye diseases in Singapore, patient-centered outcomes research, low vision outcomes and rehabilitation. The unit also focuses on translational clinical research on eye diseases, particularly diabetic retinopathy, glaucoma and AMD.


About the Population Health Research Group

Established in April 2013, the Population Health Research Group is strategically placed to interface with health research, clinical practice and health policy. Therefore, it is able to improve the utilisation of research knowledge and evidence to efficiently and effectively inform on:

  • Eye health care practices

  • Implementation of complex interventions to improve adherence to ocular disease management, ocular health, self-efficacy and quality of life

  • Guidelines and ocular program development

  • Policy development related to improving eye care in Singapore

  • Optimal assessment of patient-reported outcomes


Population Health Research Group Vision

To improve the quality of life of Singaporeans living with eye diseases and vision loss.


Population Health Research Group Mission

Through our integrated program of research, we aim to:

  • Detect and prevent eye diseases and vision impairment

  • Implement interventions and new models to improve access to care, disease management and patient outcomes

  • Develop and validate novel instruments to accurately measure patient-reported outcomes

  • Be the HSR research arm of SNEC

  • Inform policies to improve eye care in Singapore

      • Development and validation of Glaucoma Utility Index-S (GUI-S) in Singapore

      • Development and validation of the first diabetic retinopathy-specific utility instrument (DRU) using a mixed method approach and discrete choice experiment (DCE) methodology

      • Development and implementation of the Brief Impact of Vision Impairment (B-IVI) Computer Adaptive Testing System

      
    Body Composition

    • Investigate the contribution of body composition parameters to the risk of severity of DR and DME

    • Sarcopenia, frailty, and bone health   

    • Link between impairment in sarcopenia (i.e., muscle mass, muscle strength, and physical performance) and deterioration in bone mass and texture leading to an increased risk of poor functioning, mobility, falls, fractures, hospitalisation, morbidity, QoL and mortality.   

    • Establish Singapore reference norms for sarcopenia and frailty subtypes in our three ethnic groups

    • Identify mechanisms and biomarkers of sarcopenia and frailty
