BiographyDr Poemen PM CHAN graduated from The University of Hong Kong with multiple scholarships and awards, including CP Fong Gold Medal in Medicine, H.C. Liu Prizes in Anatomy, Mr & Mrs S. H. Wong Foundation Scholarship, BL Wong Scholarships and Yu Chun Keung Mem. Scholarships. He was trained in Hong Kong Eye Hospital since 2007 and was promoted associated consultant in 2014. During his ophthalmology training, he granted the HC Ho Medical Education Foundation Scholarship for his overseas clinical visit in Moorfield’s Eye Hospital (London, UK) and Prism’s Eye Institute (Toronto, Canada). During the service, he received the Best Poster Display Award in the Hospital Authority Convention 2014, Outstanding Staff and Team Award in Hospital Authority Convention 2016 and The Best Service Provider award of Hong Kong Eye Hospital.
Dr CHAN is currently the coordinator of the CUHK-HKEH-PWH International Fellowship Programme, the programme director of glaucoma surgery subspecialty for the CUHK Jockey Club Ophthalmic Microsurgical Training Programme, the Academic Coordinator of the glaucoma service of Hong Kong Eye Hospital. He is also attentive to undergraduate medical education. He is the associated head of the undergraduate division, as well as responsible for innovative undergraduate teaching that involved flipped classroom teaching and online e-learning.
Internationally, he was an invited participant of the World Glaucoma Association (WGA) Consensus Meeting XI in 2019. He serves as glaucoma subspecialty liaison for the World Ophthalmology Congress (WOC) 2018, Secretary of glaucoma subspecialty for The 33rd and 34th Asia-Pacific Academy of Ophthalmology (APAO) Congress in 2018 and 2019, as well as served as International Advisory Committee of The Association for Research in Vision and Ophthalmology- Asia (ARVO-Asia) in 2017.

Research Highlights
Research ProgrammesOcular Hypertension: risk assessment, treatment approach and the applicability of new imaging technique in the management algorithm.
Cost-effectiveness analysis of various glaucoma treatments – particularly, management approaches that could reduce medication use (which constitute the major cost of treatment) and improve quality of life.
New surgical techniques and devices of glaucoma surgery – improvement of success rate, reduction of surgical complication and the use of medication.
Genetic in glaucoma: Phenotypic characterisation, family linkage, genomic investigation of Juvenile open angle glaucoma and
Ocular imaging: new anterior segment devices, risk assessment in primary angle closure glaucoma, microvascular assessment in normal tension glaucoma and primary angle closure glaucoma
Primary angle closure disease and normal tension glaucoma – new treatment approaches, risk assessment and ocular imagining


Results of NoteDeveloped a safe, protocol-driven system of reducing medication use for patients with ocular hypertension
Established the largest number of ocular hypertensive cohort in the Asian population and currently undergoing a randomized controlled trial.
Demonstrated that combined phacotrabeculectomy is more cost-effective than phacoemulsification alone for treating primary angle closure glaucoma, as well as the importance of medication cost and how this would affect the cost-effectiveness of treatment in primary angle closure glaucoma.
Demonstrated how different methods of assessing vertical cup-to-disc ratio could affect the risk assessment for untreated ocular hypertensive eyes and how such variability could affect treatment decision.
