THE EFFECTIVENESS OF PENCIL PUSHUPS TREATMENT FOR CONVERGENCE INSUFFICIENCY

Michael Gallaway

Abstract

PURPOSE. Pencil pushups treatment (PPT) is a commonly prescribed home vision therapy approach for convergence insufficiency (CI), but there is no data to support its effectiveness.

METHODS. 25 subjects with symptomatic CI were recruited from an optometry school binocular vision clinic and a private optometric office. All subjects had 4 pd exophoria or greater at near, and were classified as definite CI if both near point of convergence (NPC) and BO vergence were reduced, or suspect CI if only one was reduced. All subjects filled out a symptom questionnaire before treatment began. They were instructed to perform pencil pushups at home with a suppression check for 15 minutes 5 days a week. To monitor compliance, we asked subjects to fill out a daily treatment form. A followup was scheduled for 6 weeks. The initial testing was repeated at this visit along with an additional symptom questionnaire.

RESULTS. 12 subjects returned for the 6 week followup. Of the 9 definite CIs, 3 showed an improvement in NPC and BO vergence that allowed them to be classified as normal, 3 improved from definite CI to suspect CI, and 3 remained definite CI. Of the 3 suspect CIs, 1 improved to normal status, and 2 remained as suspect CI. All but 1 subject experienced an improvement in symptoms, although only 1 reported an elimination of symptoms. As a group, symptoms were significantly improved using the Mann Whitney Rank Sum Test (pTHE EFFECTS OF A TOPICAL NON-STEROIDAL ANTI-INFLAMMATORY MEDICATION ON RIGID GAS-PERMEABLE CONTACT LENS ADAPTATION IN NEOPHYTE WEARERS.
