Profile

Professor Yeo obtained his Medical Degree from the National University of Singapore in 1992. He did Ophthalmology residency training in Singapore. He obtained his post-graduate Ophthalmology qualifications in 1999 and completed a further 3 years of advance surgical training. He obtained his specialist accreditation in 2003 and started to pursue a vitreoretina subspecialty training at the Singapore National Eye Centre under Prof Ang Chong Lye. In 2006, he was awarded a HMDP grant to further his vitreoretinal training in Sydney, Australia under Drs Andrew Chang and Paul Beaumont. He is currently a senior consultant vitreoretinal surgeon managing both medical and surgical retina conditions at the Singapore National Eye Centre. He is also a clinical lecturer with the NUS-YLL medical school.

Professor Yeo is a Senior Adjunct Scientist with the Singapore Eye Research Institute. His research interest includes age related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV), two very important blinding conditions in Singapore. He has engaged in primate work developing animal models for AMD and looked at novel new strategies for delivering drugs for the condition under the retina. SNEC has collaborated with the Genomic Institute of Singapore to study the genetics of AMD and PCV. He is also a Principal Investigator for a number of international clinical trials for these 2 conditions.

His other research interests include retinovascular conditions including diabetic retinopathy. He is actively involved in clinical trials for these conditions as a co-investigator.
