This literature review was undertaken to overview postural stability in strabismus and amblyopia. Postural stability is a complex skill that coordinates dynamic sensory mechanisms to facilitate sustained balance. The review discusses critical roles of vision in postural stability, e.g. postural stability is worse with eyes closed, with refractive errors and with amblyopia and strabismus. The author discusses the role of vestibular systems including awareness of body, vertical trunk alignment, regulating centre of mass and stabilising the head with respect to gravity. The role of somato-sensory systems is discussed including proprioceptive, cutaneous and joint inputs for direct data about body alignment. There is discussion of strabismus and amblyopia, different types of strabismus, strabismus treatment effect and effect of age. The author concludes binocular vision is crucial for maturation and preservation of balance control in children.
