Participant gender:
All
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.

Criteria
Inclusion Criteria:

- 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

Exclusion Criteria:

- 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
