Who can join

Age: 4 and older, up to 16. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• children with best-corrected visual acuity (BCVA) of 20/40 (equivalent to 0.3 logMAR) or worse in the amblyopic eye (ranging from 20/40 to 20/400), and interocular difference of BCVA was at least two logMAR lines,
• ocular causes of amblyopia that were identified as refractive(i.e., anisometropic, strabismus, or strabismic-anisometropic.
• Anisometropia included interocular difference of spherical equivalent >=1D or interocular difference of astigmatism cylinder magnitude >=1D;
• strabismus included those with deviation >=10PD or good alignment after prior strabismus surgery;
• combined type included those who meet the criteria of both anisometropia and strabismus.
• For the patching group, we will enroll 15 children with strabismic amblyopia who are prescribed patching treatment. Age: 4-12 years old.
• For the foveation therapy group, we will enroll 15 children with strabismic amblyopia who are prescribed foveation therapies. Age: 8-16 years old.

You may not qualify if…

• born before 32 weeks gestational age;
• neurologic, developmental, or systemic illnesses known to be associated with ocular pathologies;
• congenital or acquired macular pathology.
