What is a squint? Generally, the eyes of a person look straight and fix on the target perceived. Squint is a condition where there is ocular misalignment, in which while one eye looks straight, the other looks either inward, outward or upward. Not all newborns are endowed with straight eyes. A large population study has shown that only 30 per cent have straight eyes, 69 per cent have variable amount of outside deviation and only one per cent has inside deviation. In most cases, these deviations disappear within two months of birth, as the child would develop straight- looking eyes. However, if the condition persists, it is diagnosed as a congenital or birth squint and this deserves an eye evaluation. It is much more common to see a congenital esotropia (inside deviation/ cross eyed) than a congenital exotropia (outside deviation/wall eyed). The cause of congenital squint could be due to a combination of factors like imbalance in muscle forces, with absence of cortical fusion.
