Figure 1. Screening for Amblyopia Analytic Framework and Key Questions (KQ)
[D] Select for Text Description.
Key Questions:
- What is the prevalence of visual impairment in children younger than age 5 years?
- Do reliable, accurate, and feasible screening tests exist that can be used
to detect visual disorders in children younger than age 3 years or in children
aged 3 to 5 years? These visual disorders include amblyopia, strabismus, refractive
errors associated with amblyopia, other rarer conditions associated with amblyopia
such as cataracts or ptosis, and refractive error not associated with amblyopia.
- Do detection and treatment of conditions associated with amblyopia before amblyopia has developed lead to better treatment outcomes (primary prevention)?
- Under what conditions is the treatment of amblyopia successful?
- Under what conditions is the treatment of refractive errors not associated with amblyopia successful?
- Does improving vision result in improved health outcomes?
- What are the adverse effects of screening?
- What are the adverse effects of treatment?
Added to 2003 Update:
- Does screening for amblyopia and associated conditions in children younger than age 5 years lead to better vision outcomes?
