National Study to Explore Atropine Eyedrops for Myopia Prevention in Children
Overview
Researchers at The ohio State University and the University of Houston are initiating a national study to determine if daily atropine eyedrops can delay the onset and reduce the severity of nearsightedness (myopia) in young children. The study is funded by two grants from the National Institutes of Health totaling $25 million.
The Research & Methodology
The study will focus on children aged 6-11 years old identified as being at high risk for developing myopia. Researchers will administer daily atropine eyedrops to a randomized group of over 600 children. the study builds on previous research indicating that atropine can slow the progression of myopia *after* diagnosis. This new study uniquely aims to administer the drug *before* diagnosis, targeting children proactively.
The identification of high-risk children is based on school vision screening outcomes. Previous research suggests that children whose farsightedness decreases to a specific level by third grade have a nearly 90% chance of developing myopia by eighth grade. These children will be the primary recruitment target.
The clinical trial will be conducted at Ohio State University, the University of Houston, and an additional 12 centers across the United States.
Why Prevent Myopia? The Long-Term Health implications
Myopia is not merely a refractive error requiring corrective lenses. increasingly, it’s understood as a risk factor for serious eye diseases later in life. As Jeffrey Walline, co-principal investigator and professor of optometry at The Ohio State University, explains:
“The more nearsightedness you have, the more at risk you are as an older adult of sight-threatening complications – retinal detachments, atrophy at the back of the eye, glaucoma and macular degeneration.”

Therefore, reducing the degree of myopia, even through preventative measures, can significantly lower the lifetime risk of these debilitating conditions.
Myopia Prevalence & Trends
Myopia rates have been steadily increasing globally, particularly in East Asia and among individuals with higher levels of education. While the exact causes are multifactorial (genetics, environmental factors, near work), the rising prevalence underscores the importance of preventative strategies.
| Region | Estimated Myopia Prevalence (2020) |
|---|---|
| East Asia | >50% |
| North america | ~30-40% |
| Europe | ~25-30% |
| Australia | ~20-25% |
