CONVERGENCE INSUFFICIENCY

Convergence insufficiency (CI) is a binocular vision disorder characterized by the inability of the eyes to work together properly while focusing on a near object. When we read or look at an object close to us, our eyes need to turn inward together (converge) to maintain single, clear vision. In convergence insufficiency, this inward turning of the eyes is inadequate, and the eyes have a tendency to drift outward.

prognosis

The prognosis for treating Convergence Insufficiency (CI) with vision therapy is generally very good, and many studies support the effectiveness of vision therapy in improving the signs and symptoms associated with this condition. At Vision & Learning Center, we have had close to a 100% success rate in treating Convergence Insufficiency. 

Successful Outcomes:

  1. Symptomatic Relief:

    • Many patients experience significant or complete relief of symptoms, including reduced eye strain, headaches, and double vision, after undergoing vision therapy.

  2. Improved Convergence:

    • Vision therapy can help improve the ability of the eyes to turn inward together and can often resolve the convergence difficulties associated with CI.

  3. Enhanced Academic Performance:

    • Improvements in convergence can lead to increased comfort and efficiency in reading and other close-up tasks, potentially contributing to better academic performance.

  4. Sustained Improvement:

    • Many studies have shown that improvements achieved with vision therapy for CI are usually sustained long-term, with many patients experiencing lasting benefits. Once a vision therapy program is complete, the benefits last a lifetime. ( We cannot prevent the potential effects of a concussion, traumatic brain injury, stroke, ect. following a vision therapy program)

Individual Variations:

The degree of improvement and the time needed to achieve it can vary significantly from person to person. The success of vision therapy can depend on several factors, including the severity of the CI, the specific type and consistency of exercises performed, the age of the patient, and the presence of any co-existing conditions.

Recommended Approach:

  • Consistent Therapy: Consistency in performing the prescribed exercises is crucial for achieving optimal results.

  • Regular Monitoring: Regular follow-up with the eye care provider is essential to assess progress and modify the therapy plan as needed.

  • Combination Therapy: A combination of in-office and at-home exercises often yields the best results.

  • Addressing Co-Existing Conditions: It is important to address any co-existing conditions such as amblyopia or strabismus, as they can impact the effectiveness of the therapy.

Research Support:

The Convergence Insufficiency Treatment Trial (CITT), a significant study funded by the National Eye Institute, found that office-based vision therapy, combined with at-home reinforcement, was the most effective treatment for CI, leading to improvements in symptoms and clinical signs of CI.

In conclusion, while individual outcomes can vary, vision therapy is a well-established and clinically supported approach for managing convergence insufficiency, and many individuals undergoing this therapy experience significant and lasting improvements.
