Strabismus, also known as squint, is a condition where both eyes look at different directions at a time. In simple terms, the eyes lack coordination and mostly occur in children but can also develop in older kids and in adults as well. In this condition, if one eye is looking straight then the other eye can turn inwards (towards the nose) also known as Esotopia, outwards (away from nose) Exotropia or upwards and downwards (hypertropia).
Six muscles (extra-ocular muscles) around the eye are responsible for coordinating the movement of eyes. A normal person’s vision, both eyes aim at the same object, helping the brain to combine the two pictures received from two eyes in a single 3-D image, giving the perception of depth.
When one eye goes out of alignment in squint, two different pictures are sent to the brain, here the brain “learns” to ignore the image from the non-aligned eye, losing the perception of depth in child. But in adults, the brain has already learnt to receive two images and cannot ignore the image from misaligned eye and due to this adult develop double vision.
