Convergence Insufficiency and Attention Deficit Hyperactivity Disorder: Literature Review

Abstract

Children are subjected to a high demand for visual tasks from an early age, associated with their school activities, that can cause alterations in the oculomotor system generating symptoms that, sometimes, affect your school performance and emotional state, which leads to a closer study of binocular vision disorders such as convergence insufficiency (CI) and child behavioral disorders, They are characterized by being persistent, repetitive and inappropriate, such as attention deficit hyperactivity disorder (ADHD). The objective of this review was to identify and describe the definition, prevalence, clinical signs, the symptomatology and treatment for convergence insufficiency and how it is associated with attention deficit hyperactivity disorder through a literature review of different databases, and in which articles were identified in which the visual function of children with ADHD diagnosis was intended to be known, the presence of symptoms associated with this disorder in patients diagnosed with insufficient convergence and even clinical trials comparing changes in The results of this study were based on the results of a study conducted by the European Commission in March 1998. The results of this review lead to the conclusion that an association between ADHD and HF in children is evident, but not a causal relationship, studies on representative samples are therefore necessary.
