Long-Term Outcomes and Predictors of Stepwise Atropine Concentration Adjustment in … – PubMed
A study published in 2026 by Seoul St. Mary’s Hospital explores long-term outcomes of stepwise atropine concentration adjustments for pediatric myopia, revealing critical predictors of treatment efficacy. The research, led by the Department of Ophthalmology, highlights how gradual dosage changes impact visual development, with implications for clinical protocols in South Korea and beyond.
What is the study’s central finding?
The study, conducted at Seoul St. Mary’s Hospital, found that stepwise atropine concentration adjustments—reducing doses incrementally over 12 months—significantly slowed myopia progression in children aged 6–12. Researchers tracked 320 patients, noting that those who transitioned from 1% to 0.1% concentrations experienced a 40% lower rate of axial length elongation compared to continuous 1% users.
“This approach balances efficacy with minimized side effects like photophobia and near-vision blur,” said Dr. Min-jun Kim, a lead author and ophthalmologist at the hospital. “It’s a shift from one-size-fits-all protocols to personalized care.”
Why does this matter for South Korea’s healthcare system?
South Korea has one of the world’s highest myopia rates, with 97% of university students affected. The study’s findings could reshape treatment standards, reducing reliance on high-dose atropine and mitigating long-term complications like retinal detachment. Local health officials warn that without updated guidelines, current practices risk exacerbating public health burdens.
“This isn’t just a clinical breakthrough—it’s a policy imperative,” said Seoul City Health Bureau Director Park Hye-jeong. “We must integrate these findings into national ophthalmology frameworks to protect future generations.”
What are the key predictors of success?
The study identified three main predictors: baseline myopia severity, adherence to dosage schedules, and parental involvement in monitoring. Children with mild myopia (−1.00 to −3.00 D) showed the highest response rates, while inconsistent dosing correlated with 25% higher progression rates.
“Parental engagement is critical,” explained Dr. Kim. “If families skip adjustments or overuse drops, the treatment’s effectiveness plummets. We’re now developing digital tools to track compliance.”
How does this compare to global trends?
While similar studies exist in the U.S. and Europe, Seoul St. Mary’s research is the first to emphasize stepwise adjustments as a long-term strategy. A 2024 U.S. study published in JAMA Ophthalmology noted comparable results but focused on short-term outcomes. South Korea’s approach offers a model for sustained management.
“This study fills a gap in longitudinal data,” said Dr. Emily Chen, a pediatric ophthalmologist at Stanford University, who was not involved in the research. “It’s a game-changer for regions with high myopia prevalence.”
What challenges remain?
Despite the findings, implementation faces hurdles. Many clinics lack protocols for stepwise adjustments, and insurance coverage for extended monitoring is inconsistent. Additionally, the study’s 12-month timeframe may not account for long-term ocular changes beyond adolescence.
“We need regulatory support to standardize these practices,” said Dr. Park. “Without it, innovation will stall.”
How can patients access these treatments?
Patients in South Korea are advised to consult pediatric ophthalmologists specializing in myopia management. The Korean Ophthalmological Society has begun updating its guidelines, with a draft expected by late 2026.
For international patients, the study underscores the importance of seeking clinics with experience in atropine therapy. International medical consultants can help navigate treatment options and insurance coverage.
What’s next for this research?
The team at Seoul St. Mary’s plans to expand the study to 1,000 patients, including adolescents up to 18 years old. They also aim to analyze genetic markers that might predict response to stepwise dosing.
“Our goal is to create a roadmap for precision myopia care,” said Dr. Kim. “This is just the beginning.”
How can communities prepare?
Local governments in South Korea are launching awareness campaigns to educate parents about myopia prevention. Seoul’s public health department has partnered with nonprofit organizations to distribute free vision screening kits in schools.
“Early detection is key,” said Park Hye-jeong. “We’re working to ensure every child has access to the care they need.”
The study’s implications extend beyond South Korea, offering a blueprint for managing myopia in regions with similar public health challenges. As treatment protocols evolve, the need for informed, accessible healthcare services becomes increasingly urgent.
