The critical period for amblyopia treatment (after which treatment is unlikely to be effective) ends at approximately:

• A 7–8 years of age (end of sensitive period for visual cortex plasticity) ✓
• B 3 years of age
• C 12 years of age (onset of puberty)
• D 5 years of age strictly, with no response after this

Explanation

The visual cortex exhibits maximum plasticity (sensitive period) from birth to approximately 7–8 years of age (some sources extend to 9–10 years). Amblyopia treatment (patching, penalization, vision therapy) is most effective before this age. After 7–8 years, the visual cortex becomes progressively less responsive to treatment, though mild improvement can occur even in adolescents. The critical period concept underscores the urgency of early detection via visual screening programs.
