Patient's question:
Pediatric strabismus and amblyopiaDoctor's answer:
Strabismus is caused by abnormal eye muscle movement due to an imbalance in the muscles that control the eyes. The random movements of a newborn's eyes are normal. Generally, the eyes start moving together a few weeks after birth. If a baby's eyes cannot move in the same direction (one up, one down), it may be a sign of strabismus.
