title: Lyme disease and convergence insufficiency: is it a near fit?
abstract: OBJECTIVE
  The purpose of this study is to determine the prevalence of convergence insufficiency (CI) in patients who have been diagnosed with Lyme disease.
  
  
  RESULTS
  This study is a retrospective review of charts from 190 patients with confirmed Lyme disease. The diagnosis of CI is based on decreased fusional convergence amplitudes at near fixation. The number of patients with CI was reviewed as well as information on patient gender, age, and symptoms. Seventy percent of patients in this study were female. Ages ranged from 4 to 80 years old. Fifty-three percent of patients with Lyme disease had CI. Symptomatic patients were treated with orthoptic exercises or vision therapy.
  
  
  CONCLUSIONS
  Patients diagnosed with Lyme disease seem to develop CI. Symptomatic CI associated with Lyme disease seems to respond well to conventional CI treatment.
