Vision therapy for convergence insufficiency and accommodative dysfunction in children

Record ID 32014000408
Authors' recommendations: Vision dysfunction can be congenital or can result from an acquired brain injury, and is characterized by abnormalities in accommodation and vergence such as convergence insufficiency and accommodative dysfunction. Convergence insufficiency is an impairment of binocular vision, i.e., the inability for both eyes to work together when looking at something that is near. Signs include intermittent exotropia (one eye may turn outward), reduced near point of convergence (NPC), and reduced convergence amplitudes. Common symptoms include double vision (diplopia), eyestrain, intermittent blurring, motion sickness, inability to concentrate, headaches, and a generalized decrease in visual awareness or constricted fields, among others. Quality of life is impacted in children with impaired binocular vision since it affects reading, sports, and other activities. The American Academy of Optometry (AAO) estimates that the median prevalence of convergence insufficiency in the population is 7%, and that the prevalence is similar for adults and children. Standard therapy for visual dysfunction can be categorized broadly as optical correction, including added lens power and prism; pharmaceutical agents; extraocular muscle surgery; and vision therapy.
