Brief Summary

This study was a randomized, double-blind, placebo-controlled, multicenter, superiority design, phase III clinical trial to compare the efficacy and safety of two low-concentration atropine sulfate eye drops versus placebo in delaying myopia progression in children.

Eligibility Criteria

Age6 Years - 10 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Child (female or male) aged 6 to 10 years.
  • Myopia (SER of at least -0.50 D and no more myopic than -6.00 D) in each eye as measured by cycloplegic autorefraction.
  • If present, astigmatism of ≤1.50 D in each eye as measured by cycloplegic autorefraction.
  • Anisometropia SER of \< 1.50 D as measured by cycloplegic autorefraction.

You may not qualify if:

  • History of any disease or syndrome that predisposed the subject to severe myopia (e.g.,Marfan syndrome, Stickler syndrome, retinopathy of prematurity).
  • History in either eye of abnormal ocular refractive anatomy (e.g., keratoconus, lenticonus,spherophakia).
  • Chronic use of any topical or systemic antimuscarinic/anticholinergic medications (e.g.,atropine, scopolamine, tropicamide) within 21 days prior to screening and/or anticipated need for chronic use during the study period (i.e., more than 7 consecutive days in 1 month or more than 30 total days in 1 year).
  • Use of cycloplegic drops for dilated ocular exam was allowable.
  • Heart rate persistently (for more than 10 minutes) \> 120 beats per minute.
  • Allergy to study drugs.
