Does Iris Color Affect Atropine?

Meta-analysis examines whether iris color influences atropine 0.01% and 0.05% efficacy in myopia

1

A post-hoc meta-analysis examined the influence of iris color on the efficacy of low-dose atropine in myopia management.
2

The study found that children with non-brown irides showed significantly less myopia progression with atropine 0.01% compared to placebo.
3

No significant treatment effect was observed in children with brown irides treated with atropine 0.01%, suggesting potential reduced efficacy.
4

Atropine 0.05% did not show iris color-related differences in efficacy, indicating higher concentrations may overcome potential limitations.
5

The findings raise questions about tailoring atropine dosing based on iris color, though the authors caution against immediate practice changes.
