Convergence Insufficiency and Binocular vision Dysfunction
Binocular vision dysfunction is a problem with how the two eyes work together to maintain single, clear, comfortable vision at all distances. Binocular vision dysfunction can be a developmental problem in children or can develop due to disease, trauma, the natural aging process, or excessive technology use. Problems with how the eyes work together may cause symptoms of:
Double or overlapping vision
Headaches associated with near work
Words moving on the page while reading
Eyes get tired while reading
Vision going in and out of focus
Poor depth perception
Convergence insufficiency is the most common binocular vision disorder in both children and adults. Convergence insufficiency is when the eyes have difficulty turning in when looking up close to keep vision single. An estimated 8-12% of the population has convergence insufficiency. An association has been found between ADHD and convergence insufficiency, making it worthwhile for children with attention problems to be evaluated for possible CI.
Other binocular vision disorders include:
Convergence excess- eyes turn in too much when looking up close
Vertical Heterophoria- eyes are misaligned vertically
Divergence excess- eyes turn out too much when looking at far
Divergence insufficiency- eyes do not turn out enough when looking at far
Convergence insufficiency and other binocular vision disorders can be effectively treated with a program of optometric vision therapy.
