NCT00094614

Brief Summary

The goals of this study are:

  • To compare the visual acuity outcome in the amblyopic eye after 17 weeks of daily use of atropine versus weekend-only use of atropine.
  • To compare the proportion of patients achieving a complete treatment response (defined as amblyopic eye acuity \>20/25 or equal to that of the sound eye in the absence of a reduction in the sound eye acuity from baseline) with daily atropine versus weekend-only atropine.

Eligibility Criteria

Age3 Years - 7 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Age \< 7 years
  • Able to measure surrounded single optotype visual acuity using the ATS single-surround HOTV protocol (this will in effect exclude all patients \<2 years old and many \<3 years old)
  • Amblyopia associated with strabismus, anisometropia, or both
  • If anisometropia is present (as per protocol definition), refractive error corrected with spectacles for a minimum of 4 weeks
  • Visual acuity in the amblyopic eye \< 20/40 and \>20/80
  • Visual acuity in the sound eye \> 20/40 and inter-eye acuity difference \>3 logMAR lines

You may not qualify if:

  • Amblyopia treatment (other than spectacles) in the past month and no more than one month of amblyopia treatment in the past 6 months
  • Myopia more than a spherical equivalent of -6.00 D in the amblyopic eye
  • Myopia more than a spherical equivalent of -0.50 D in the sound eye
