Retina Research Group


The SERI Retina group comprises of clinicians, clinician-scientists and scientists with a broad focus and expertise in basic, translational and clinical research in characterizing molecular mechanisms and pathways, epidemiology, imaging and management of retinal disorders. Particularly, the group emphasises Asian Age-related Macular Degeneration (AMD), including polypoidal choroidal vasculopathy (PCV), diabetic retinopathy (DR) and other retinal disorders, such as central serous chorioretinopathy (CSR).


  • Clinical expertise in management of Asian retinal diseases

  • Clinical cohorts of  >2,000 patients with AMD and DR

  • Epidemiological and genetic database on >10,000 patients

  • State-of-the-art animal facility with animal models for retinal diseases

  • World-class Retinal Imaging & Ocular Grading Centre

  • SIPRAD – An industry standard platform in retinal angiogenic diseases
