The first, published in Archives of Ophthalmology demonstrated that computer exercises when combined with office based vision therapy/orthoptics were more effective than "pencil pushups" or computer exercises alone for convergency insufficiency in 9- to 18-year-old children. Figure 2 outlines the treatment sequence. Convergence insufficiency is often associated with symptoms such as frequent loss of place while reading, loss of concentration, having to re-read, reading slowly, poor comprehension, sleepiness, blurred vision, diplopia, headaches, and/or eyestrain. The NTP group will be assigned placebo home-based computer vergence/accommodative therapy (5 minutes/day) plus near target push-ups (15 minutes/day) for a total of 20/minutes per day, 5 days per week for the 12-week treatment phase. The number of subjects who are classified as a success based on the mean NPC break at the 6-week visit.

Although home-based therapy using computer software is becoming more popular, no prospective data are available to demonstrate the effectiveness of home-based vision therapy using computer software compared to home-based near target push-ups or home-based placebo computer therapy. Most children given in-office therapy showed normal vision or significant improvement in symptoms after 12 weeks. Convergence insufficiency (CI) is a common and distinct binocular vision disorder that affects approximately 4% of school age children and adults in the United States. There are significant differences in contact time, complexity, and cost between office-based and home-based therapy for CI. About this study.

A combination of in-office and at-home orthoptics and vision therapy probably represents the best therapeutic approach for convergence insufficiency. Placebo computer-based therapy will be provided by the Home Therapy System (HTS) computer software. Diagnosis of CI was based on the published criteria from the “Convergence insufficiency treatment trial (CITT)” 18, 19: (1) exophoria at near (0.4 m) at least four prism diopters (∆) greater than at far (6 m); (2) a receded NPC break of 6 cm or greater; and (3) insufficient PFV at near (PFV less than twice the amount of the near phoria) or a break on PFV of ≤15 ∆ base‐out.

In 2005, the Convergence Insufficiency Treatment Trial (CITT) published two randomized clinical studies. The clinical profile of the cohort at baseline was 9Δ exophoria at near (+/− 4.4) and 2Δ exophoria (+/−2.8) at distance, CISS score = 30 (+/−9.0), NPC = 14 cm (+/− 7.5), and near positive fusional vergence break = 13 Δ (+/− 4.6). PFV is recorded as the prism magnitude where vision is first blurred (or break if no blur is reported). Success is based on the Convergency Insufficiency Symptom Survey (CISS) defined as improvement of 9 or more points from baseline and a 12-week score of <16 points. Abstract. The number of subjects classified as a success based on signs/symptoms at the 6-week visit. Overall success was defined as meeting all of the following criteria at 12 weeks: Pairwise treatment group comparison (HB-C versus Placebo) of the percentages of participants meeting success criteria using binomial regression adjusting for baseline covariates of CISS score (<28 points vs ≥ 28 points), mean NPC break (<10 cm vs ≥ 10 cm), and mean PFV blur (≥ 15 PD vs <15 PD) using linear contrasts with Bonferroni adjustment for multiple comparisons.
