PurposeTo evaluate the efficacy of a home-based computer orthoptic program for symptomatic convergence insufficiency (CI) in children.MethodsThe medical records of participants aged 5 to <18 years who were diagnosed with symptomatic CI and were treated with the Computerized Vergence System (CVS) program were retrospectively reviewed. All participants were prescribed 9 or 15 minutes of daily convergence exercises with the CVS program, 5 days per week, for the initial 6 weeks. Near point of convergence (NPC) and near convergence amplitude (NCA) were measured at baseline, 6 week, and final examinations. The presence or absence of diplopia and asthenopia with reading were recorded at baseline and final examinations.ResultsA total of 186 participants were included. At diagnosis, 72 participants (39%) reported diplopia and 182 (98%), reported asthenopia. At final examination, 172 participants (92%) were asymptomatic. Twelve participants (6%) subsequently received other treatment modalities. Mean NPC at baseline (5.9 cm) improved after 6 weeks of CVS therapy (3.3 cm) and at final examination (2.9 cm; P < 0.0005). Mean NCA at baseline (20.3Δ) improved after 6 weeks of CVS therapy (37.0Δ) and at the final examination (38.0Δ; P < 0.0005).ConclusionsIn this study, home-based CVS therapy reduced symptoms related to CI and improved the NPC and NCA of most children aged 5 to <18 years with symptomatic CI.
