Infantile ET will typically present before __________ months of age.

• A. 4 months
• B. 6 months
• C. 9 months
• D. 12 months

Answer: (B)

Infantile esotropia is an eye misalignment that appears very early in life, typically within the first six months. This early onset points to a developmental issue in the infant’s vergence system rather than a refractive-accommodation problem. Because accommodative or other later-onset forms tend to emerge after several months as visual experience and refractive status come into play, the standard cutoff used to define infantile esotropia is presentation before six months of age. Among the given options, six months best fits this early-onset window, while the other ages fall outside the usual timeframe for infantile presentation.
