Which of the following is a key characteristic of infantile esotropia?

Infantile esotropia is characterized by a cross-eyed condition that typically appears within the first six months of life and is often associated with significant misalignment of the eyes. A key characteristic of this condition is that it can indeed be treated through surgical intervention, or by the use of botulinum toxin, which can help in repositioning the eye muscles. Surgical correction is particularly common and is considered a standard approach when other non-invasive treatments are insufficient.

This condition does not primarily correspond with known genetic factors, nor is it limited to affecting just one eye. Diagnosis generally occurs much earlier than the age of five; thus, the timing of diagnosis is also an important distinction when considering the characteristics of infantile esotropia.
