Question
Why does a child’s eye become crossed if their neighbor’s child has developed strabismus?
Answer
Strabismus is usually caused by several factors:
- Imbalances in the ocular motor control center, commonly seen in congenital strabismus.
- Incomplete development of visual function, where binocular single vision function has not matured and cannot effectively coordinate the extraocular muscles.
- Immature refractive system, often leading to myopia in children, which can cause excessive accommodation and result in esotropia.
- Congenital anomalies, such as abnormal extraocular muscle anatomy or muscle nerve palsy.
