Alternating convergent strabismus is considered normal until what age in infants?

Alternating convergent strabismus is considered normal until what age in infants?

• A. 2 months
• B. 4 months
• C. 6 months
• D. 9 months

Answer: (C)

Normal binocular vision is still maturing in the first months of life. An alternating inward-turning eye can be a harmless part of this development and is commonly seen up to about six months of age. By around six months, most infants have developed more stable eye alignment and fusion. If the inward turn persists after this age, or if there is a constant misalignment, it warrants evaluation for conditions such as congenital esotropia or refractive/neurologic issues.
