One eye will be pointing straight and the other either turned in, out, up or down. Eye movements are controlled by eye muscles. If one muscle is stronger, the eye is turned towards the stronger muscle. It may indicate a serious disease hence always consult an eye specialist as early as possible. Treatment of squint should be as early as possible.
Children never outgrow squint.
It should be corrected before 5 years of age. Squint can be treated by spectacles, eye exercises or surgery. The eye specialist is the best judge and will advise you the correct treatment. The earlier the treatment, the better the results. If left untreated it may lead to permanent loss of vision in that eye.
