Title: A Randomized Trial Comparing Patching Versus Atropine for Amblyopia in 7 to < 13 Year Olds
Brief Summary: The purpose of this study is:

* To compare the effectiveness of weekend atropine plus near activities and daily patching plus near activities for moderate amblyopia (20/40 to 20/100) and severe amblyopia (20/125 to 20/400) in improving vision in the amblyopic eye of 7 to \<13 year olds.
* To determine the maximum improvement in vision of the amblyopic eye with each treatment.
* To determine whether amblyopia is associated with structural abnormalities of optic nerve fiber layer.


Options:
A: Inclusion Criteria:

* Age 3 to \< 10 years
* Amblyopia associated with strabismus, anisometropia, or both
* Visual acuity in the amblyopic eye between 20/32 and 20/63 inclusive
* Visual acuity in the sound eye 20/32 or better and inter-eye acuity difference \>= 2 logMAR lines
* Current/previous treatment with patching and/or atropine subject to the following stipulations:

  * No simultaneous treatment with patching and atropine in the past 6 months
  * No prior use of atropine in combination with the sound eye spectacle lens reduced by more than 1.50 D
  * Maximum level of any previous treatment:

    * Patching: up to 42 hours per week (averaging 6 hours daily)
    * Atropine: up to once daily
  * Current treatment with 42 hours per week patching or daily atropine
* No improvement in best-corrected amblyopic eye visual acuity between two consecutive visits at least 6 weeks apart using the same testing method and optimal spectacle correction (if needed), with no improvement defined as follows:

  * No lines of improvement
  * For patients tested using E-ETDRS, letter score that is no more than 4 letters improved
* Wearing spectacles with optimal correction (if applicable)
* Investigator ready to wean or stop treatment

Exclusion Criteria:

* Current vision therapy or orthoptics
* Ocular cause for reduced visual acuity
* Prior intraocular or refractive surgery
* Strabismus surgery planned within 10 weeks
* Known allergy to atropine or other cycloplegic drugs
* Known skin reactions to patch or bandage adhesives
* Down Syndrome present
B: Inclusion Criteria:

* Patients must be 7 years old or younger with amblyopia due to strabismus or anisometropia
* Visual acuity in the amblyopic eye must be between 20/40 and 20/100
* Visual acuity in the sound eye or 20/40 or better
* At least 3 lines of acuity difference between the two eyes

Exclusion Criteria:

* More than two months of amblyopia therapy in the past two years
* Myopia (more than -0.50 D)
C: Inclusion Criteria:

* Patients must be aged 7 to \<18 years and have amblyopia associated with strabismus, anisometropia, or both.
* Visual acuity in the amblyopic eye must be 20/40 to 20/400 inclusive and visual acuity in the sound eye must be 20/25 or better.

Exclusion Criteria:

* Patients must not have received amblyopia treatment (other than spectacles) in the past month or more than one month of amblyopia treatment in the last 6 months.
D: Inclusion Criteria:

* Age 7 to 12 years old (inclusive)
* Amblyopia associated with strabismus, anisometropia, or both
* Visual acuity in the amblyopic eye 19 to 71 letters on Electronic Early Treatment Diabetic Retinopathy Study (E-ETDRS©) (20/40 to 20/400 inclusive)
* Visual acuity in the sound eye 79 letters or better on E-ETDRS© (20/25 or better)
* Interocular difference \>=15 letters (3 lines)
* Spectacles, if needed, worn for at least 16 weeks or visual acuity documented to be stable

Inclusion Criteria for Optional Ancillary Study:

* Enrolled into the main study
* Refractive error in both eyes between -0.25 and +5.00D, inclusive (to avoid the need to adjust for refractive error)
* Birth weight \>1500 grams
* No history of Central Nervous System (CNS) disease (e.g. intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL), meningitis, developmental abnormalities of the brain, hydrocephalus, cerebral palsy, hypoxic ischemic encephalopathy

Exclusion Criteria:

* Amblyopia treatment (other than spectacles) in the last 6 months
* Myopia (more than -0.25D spherical equivalent) in either eye
