Dr Weijie Poh

Dr Weijie Poh, PhD, is the Chief Scientist of Digital Life Line, a health technology company focussed on transforming community-based eye care through intelligent and accessible diagnostic solutions. With a background spanning healthcare innovation, medical technology, and clinical operations, Dr Poh has led the commercialisation of AVAT and MIDAS—2 scalable devices designed to enable accurate self-guided visual acuity testing and on-the-spot cataract detection that empowers non-specialists to detect cataracts with precision.

Prior to Digital Life Line, Dr Poh worked closely with clinicians across primary and specialist care to design technology-enabled pathways that improve diagnostic accuracy and patient access. He brings a unique industry perspective on how digital health tools can be integrated into clinical workflows to address real-world challenges – from underdiagnosis to workforce limitations – while preserving the integrity of patient care. 

Presentation Synopsis
HE 7 - Closing the Loop: How Automated Vision Screening Strengthens Primary-to-Tertiary Eye Care
The gap between primary community care and specialised tertiary eye services remains a critical challenge in healthcare systems worldwide. Long wait times, uneven access, and inefficient referrals strain resources and delay vision-saving interventions. This talk explores how self-guided, automated vision screening devices act as a transformative engineering solution—seamlessly connecting community screenings to hospital-based care.

We will discuss:

• The Burden of Fragmented Eye Care: How reliance on centralised tertiary centers creates bottlenecks and limits early detection. 
• Engineering for Decentralisation: The role of automated, AI-enhanced screening devices in enabling accurate, scalable vision assessments outside traditional clinics. 
• Bridging the System: How these tools have the potential to streamline referrals, prioritise high-risk cases, and reduce unnecessary hospital visits. 
• Real-World Impact: Case studies showing community vision screening outcomes conducted with the automated devices.

By closing the loop between community and hospital care, this technology redefines the patient journey—ensuring timely interventions while alleviating pressure on tertiary infrastructure. The session will conclude with a forward-looking discussion on scaling this model for national digital health strategies.
