Convergence Insufficiency

Convergence insufficiency (CI) is a common eye-teaming problem in which the eyes have a strong tendency to drift outward when reading or doing work close up. Double vision often occurs if an eye drifts out. To avoid seeing double, a child with CI must use extra effort to make the eyes turn back in. This extra effort can lead to annoying symptoms, such as eye strain, blurred or double vision, loss of concentration, and frequent loss of place when reading and working up close.

Children with CI have more symptoms and show worse attention when reading than children without CI. Research has shown that treatment using office-based accommodative-vergence vision therapy improves symptoms in children affected with CI.
