The Alarming Rise of Glaucoma Cases in Singapore's Younger Adults
Singapore's eye health landscape is facing a concerning trend: a notable increase in glaucoma diagnoses and surgeries among individuals in their 40s and 50s. According to recent data from the Singapore National Eye Centre (SNEC), glaucoma operations for patients aged 40 to 49 have nearly tripled, rising from 22 cases in 2015 to 60 in 2025. Similarly, surgeries for those aged 50 to 59 almost doubled, from 95 to 183 over the same period. This surge is largely attributed to untreated high myopia from earlier years, highlighting the long-term consequences of the nation's myopia epidemic.
Glaucoma, often called the 'silent thief of sight,' damages the optic nerve due to elevated intraocular pressure, leading to irreversible vision loss if undetected. While typically associated with those over 60, these figures indicate a shift toward younger demographics, prompting urgent calls for awareness and preventive measures.
Understanding Glaucoma and Its Devastating Impact
Glaucoma encompasses a group of eye conditions characterized by progressive optic nerve damage, primarily from fluid buildup that raises pressure inside the eye. Primary open-angle glaucoma (POAG), the most common form, develops gradually without early symptoms, making regular screening essential. In advanced stages, it causes peripheral vision loss, tunnel vision, and eventual blindness.
In Singapore, SNEC manages over 40,000 glaucoma cases annually, performing more than 600 surgeries and 1,300 laser procedures. The rise in younger patients underscores the need for early intervention, as vision loss is permanent once optic nerve damage occurs.
Singapore's Myopia Epidemic: A Ticking Time Bomb
Singapore earns the moniker 'myopia capital of the world,' with prevalence rates among the highest globally. Approximately 65% of primary school children and 80-83% of young adults are myopic, and 20% of young adult myopes progress to high myopia (spherical equivalent worse than -5.00D or 500 degrees). High myopia elongates the eyeball, thinning the retina and sclera, predisposing individuals to complications like myopic macular degeneration (MMD) and glaucoma.
The Singapore Epidemiology of Eye Diseases (SEED) study, led by Prof. Saw Seang-Mei at Duke-NUS Medical School, reveals that 36% of adults aged 40-80 have myopia, with 6% high myopia. Among high myopes, 30% develop MMD, estimating over 24,000 cases in those aged 45-54 by 2025. Projections suggest 80-90% of adults over 18 will be myopic by 2050, amplifying future glaucoma risks.
The Direct Link Between Untreated Myopia and Glaucoma Risk
High myopia increases glaucoma risk by 2-3 times. Elongated eyeballs strain the optic nerve, making it vulnerable even at normal pressures. SEED studies show moderate myopia and longer axial length independently raise POAG odds. Joint effects of high intraocular pressure (IOP) and myopia further elevate risk, as confirmed in multi-ethnic analyses from SERI.
Untreated childhood myopia progresses unchecked, manifesting as glaucoma decades later. Previous generations lacked effective controls, contributing to today's surge. SERI's Pathologic Myopia Group (PMG) uses OCT and MRI to study scleral stress in myopic-glaucoma patients, revealing heightened sensitivity to IOP.

Research Driving Insights: SERI and Duke-NUS Contributions
The Singapore Eye Research Institute (SERI), affiliated with NUS and Duke-NUS Medical School, leads myopia-glaucoma research. Over 20 years, SERI's Myopia Research Group explores genetics, epidemiology, and interventions. The SEED-High Myopia (SEED-HM) study tracks 700 highly myopic adults, assessing pathologic changes via OCT and angiography.SERI Myopia Research
GUSTO Light/FitSight study (NUS-linked) shows Singapore children average low outdoor light (<5000 lux), linking insufficient outdoor time to myopia onset. Prof. Saw's SEED data informs public health strategies. Recent collaborations like SONIC 2.0 ($21M with Santen) target glaucoma and myopia treatments.

Progress in Childhood Myopia Control: Slowing the Tide
Positive news: Primary 1 myopia dropped from ~30% mid-2000s to 26% recently, thanks to screenings (K1-P4) and interventions like low-dose atropine drops (ATOM studies: 0.01% slows progression 50-60%) and myopia-control lenses (up to 71% reduction). Orthokeratology and multifocal contacts also effective.
However, uptake lags: <10% opt for control lenses due to costs ($580 vs. $200 standard) and unregulated 'copycats.' Myopia Society of Singapore (founded Dec 2025) pushes guidelines and education. SERI trials combine atropine with lenses, showing promise. Parents: 2 hours daily outdoors recommended.
Challenges: Awareness, Access, and Cost Barriers
Despite advances, complacency risks resurgence. Myopia normalized; high costs deter interventions. Copycat products flood market, lacking efficacy. Glaucoma screening access improves via diabetic/corporate programs, aiding early detection.
Myopia Society plans 2026 events, consumer guides, and Academy of Medicine consensus. For medical professionals, academic career advice supports eye health research roles.
Glaucoma Management and Innovations at SNEC
SNEC offers drops, lasers (SLT), and surgeries like trabeculectomy, MIGS. New: PreserFlo MicroShunt reduces IOP 35% (22.1 to 14.3 mmHg), controlling 48% without meds year 1. Suitable for uncontrolled POAG on max drops. LASIK safe for glaucoma risk; monitor ICLs.

Stakeholder Perspectives and Calls to Action
Dr. Foo Li Lian (SNEC): 'Lifelong high myopia risks demand vigilance.' Dr. Ng Wei Yan: 'Myopia normalization delays action.' Prof. Saw Seang-Mei's SEED drives policy.
Actionable: Annual screenings post-40, myopia checks kids 6+, outdoors, controls. Parents/students: prioritize vision for future. Researchers at Duke-NUS/SERI advance solutions.
Future Outlook: Preventing a Vision Crisis
Glaucoma cases may rise without sustained efforts. By 2040, 85,800 over-60s affected (+43%). High myopia cohort (13% from 1996 NS data) enters risk age. Myopia Society, SERI trials promise control.
