Resources for Convergence Insufficiency diagnosis available The 2008 Convergence Insufficiency Treatment Trial clearly supports the superiority of office-based vision therapy to home-based vision therapy alone for convergence insufficiency. As noted in the AOA’s Clinical Practice Guideline (CPG) on Care of the Patient with Accommodative and Vergence Dysfunction, home-based vision therapy may be less effective than in-office therapy because no therapist is available to correct inappropriate procedures or to motivate the patient.
A follow-up study published in Archives of Ophthalmology in October 2008 found that among 221 children ages 9 to 17 years with symptomatic convergence insufficiency, 73 percent receiving office-based vision therapy.
 In 2005, the Convergence Insufficiency Treatment Trial (CITT) published two large, randomized clinical studies examining the efficacy of orthoptic vision therapy in the treatment of symptomatic convergence insufficiency. Although neither study examined reading efficiency or comprehension, both demonstrated that computerized home orthoptic exercises, when combined with weekly in-office vision therapy, were more effective than "pencil pushups" (a commonly prescribed home-based treatment) for improving the symptoms of asthenopia and the convergence ability of the eyes.  The design and results of at least one of these studies has been met with some reservation, questioning the conclusion as to whether intensive office-based treatment programs are truly more efficacious than a properly implemented home-based regimen.  The CITT has since published articles validating its research and treatment protocols.  Its most recent publication suggested that home-based computer therapy  combined with office based vision therapy.
