Amblyopia or lazy eye is a vision alteration caused by an asymmetry in the position of the eyes. It usually develops at a very early age and is the leading cause of childhood vision loss.
We speak of childhood strabismus when a child suffers an alteration in the alignment of the eyes that causes them not to look simultaneously at the same point. Strabismus can occur in adults too.
“Adult strabismus” is considered to be those cases of strabismus (the eye axes are not aligned with the object of fixation) that arise from the age of 6-8 years.
It is very important to check children’s vision. Some conditions, such as amblyopia, can be treated in babies and small children, but are irreversible once the child is grown up.
