Convergence Insufficiency. Convergence insufficiency is a common vision disorder in which a person's eyes tend to drift outwards when they try to use their eyes together up close. When reading, people with convergence insufficiency frequently lose their place or have to re-read text. It is important to note that an OT cannot diagnose a convergence insufficiency. Most likely one to two children in every classroom have this condition. Children with convergence insufficiency are often thought to be lazy or disruptive in the classroom. The symptoms and signs associated with convergence insufficiency are related to prolonged, visually demanding, near-centered tasks. The most commonly prescribed treatment is home-based exercises, such as pencil push-ups, although specific methodologies vary among practitioners. Results from the earlier Convergence Insufficiency Treatment Trial (CITT), published in Ophthalmology in 2008, showed office-based vision therapy to be the most effective treatment for improving convergence and ameliorating symptoms, and that treatment effects were long-lasting.

The person cannot bring their eyes inward and maintain good binocular vision at a point more than 10 cm., Third, people with convergence insufficiency also have low fusional vergence ranges. We normally have a range in which our muscles can diverge or converge our eyes. Home-based treatment with pencil pushups or computer programs hasn't been shown to be as effective. All four CITT RCTs were rated at low risk of bias. If convergence insufficiency isn’t causing symptoms, you generally don’t need treatment.
