There were no statistically significant nor clinically relevant differences between treatment groups with respect to baseline characteristics (p > 0.05).Conclusion: Hallmark features of the study design include formal definitions of conditions and outcomes, standardized diagnostic and treatment protocols, a placebo treatment arm, masked outcome examinations, and the CISS score outcome measure. Main Outcome Measures: Convergence Insuffi-ciency Symptom Survey score after 12 weeks of treat-ment. The number of subjects who are classified as a success based on the mean NPC break at the 6-week visit. Success is based on the mean NPC (near point of convergence) break is defined as having a mean NPC break of <6 cm at 6 weeks and a 6-week to baseline ratio of <0.763 for mean NPC break. Placebo computer-based therapy will be provided by the Home Therapy System (HTS) computer software. While the home-based therapies in the CITT were not as effective as office-based vergence/accommodative therapy there was some improvement noted. Please refer to the procedures manual for further details. An alphabet pencil will be used as the target and an index card placed in the background will provide physiological diplopia control. Objective: This report describes the design and methodology of the Convergence Insufficiency Treatment Trial (CITT), the first large-scale, placebo-controlled, randomized clinical trial evaluating treatments for convergence insufficiency (CI) in children.We also report the clinical and demographic characteristics of patients. Our patients cover a board spectrum of demographics with approximately 2/3rds being neuro-typical and the remaining 1/3rd having an additional diagnosis such as ADHD, Autism, or other developmental delays. At enrollment, subjects will be prescribed 15 minutes/day of active home-based computer therapy for 5 days/week during the 12 week treatment phase. Success is based on the Convergency Insufficiency Symptom Survey (CISS) defined as improvement of 9 or more points from baseline and a 6-week score of <16 points.

Shaun original wrote a 2-part article here on the Risk and Recovery Process Following Concussions in Sports and The Role of Rehabilitation Following Concussions.In this new post, Shaun shares more thoughts on the treatment of concussions, specifically regarding convergence insufficiency. About this study. The Convergence Insufficiency Treatment Trial–Attention & Reading Trial (CITT-ART) was a multicenter, double-masked, randomized clinical trial designed to determine if office-based vergence/accommodative therapy resulted in improvements in reading 16 and attention in 9- to 14-year-old children with symptomatic convergence insufficiency. Convergence Insufficiency Symptom Survey (CISS) Administration Convergence Insufficiency Symptom Survey (CISS) Description The CISS is a 15-item questionnaire designed to assess the severity of the subject’s convergence insufficiency (CI) symptoms. 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). The placebo group will be assigned placebo home-based computer vergence/accommodative therapy (15 minutes/day) plus placebo yoked prism flipper therapy (5 minutes/day) for a total of 20/minutes per day, 5 days per week for the 12-week treatment phase. The Convergence Insufficiency Treatment Trial (CITT) Study Group. Please refer to the procedures manual for further details. Vergence Eye Movements. 246 Convergence Insufficiency Treatment Trial (CITT), demonstrated that a 12-week program of 247 office-based vergence/ accommodative therapy with home reinforcement was more effective 248 than home-based near target pencil push-ups, home-based computer accommodative therapy Thus, the Convergence Insufficiency Treatment Trial - Attention & Reading Trial (CITT-ART) was designed as a prospective randomized trial to determine whether reading and attention improve in school-aged children with symptomatic CI who are treated with OBVAT. Convergence Insufficiency Treatment Trial (CITT) Investigator Group.

To evaluate the kinetics of change in symptoms and signs of convergence insufficiency (CI) during 12 weeks of treatment with commonly prescribed vision therapy/orthoptic treatment regimens. This study was a masked, placebo-controlled, multicenter,randomizedclinicaltrialinwhichyoungadults19to Optom Vis Sci. Mitchell Scheiman, FCOVD, has completed the 12-week study, known as the Convergence Insufficiency Treatment Trial (CITT), found that approximately 75 percent of those who received in-office therapy by a trained therapist plus at-home treatment reported fewer and less severe symptoms related to reading and other near work after the office-based vision therapy. A recently completed randomized clinical trial, the Convergence Insufficiency Treatment Trial (CITT), demonstrated that a 12-week program of office-based vergence/ accommodative therapy with home reinforcement was more effective than home-based near target pencil push-ups, home-based computer accommodative therapy plus pencil push-ups, or office-based placebo therapy in treating the symptoms and signs associated with symptomatic CI in children 9 to 17 years of age. Choosing to participate in a study is an important personal decision. The number of subjects classified as a success based on clinical measures of CI (mean NPC break & mean PFV blur) at the 12-week visit. Please refer to the procedures manual for further details.

He is a graduate of Indiana University where he completed a residency in binocular vision and pediatrics. Information provided by (Responsible Party): The purpose of this study is to determine the effectiveness of home-based computer therapy for symptomatic convergence insufficiency (CI) compared to traditional home-based near target push-ups and placebo treatment. Oxford University Press; 2015. have attention problems during reading tasks and that the successful treatment of symptomatic CI can lead to improved attention during reading. Ophthalmic Epidemiol. 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. I would like to congratulate Scheiman and colleagues for venturing into this area where, truly, not many randomized clinical trials have been done. For myopia, the SE must be within 0.25D of the full myopic correction. Talk with your doctor and family members or friends about deciding to join a study. Relocation outside of area of an active PEDIG site within the next 15 months is not anticipated. The current study is a multi-center randomized clinical trial to evaluate the effectiveness of home-based computer vergence/accommodative therapy and home-based near target push-ups in children 9 to <18 years of age with symptomatic CI. Main Outcome Measures—Convergence Insufficiency Symptom Survey (CISS) score after 12 weeks of treatment. reinforcement (OBPT) as treatments for symptomatic convergence insufficiency (CI). protocols (some studies measure near point of convergence with a pencil, whereas others use an accommodative target that may alter measurements). Success is based on the mean PFV (positive fusional vergence) blur, defined as having a mean PFV blur of >15 pd at 6 weeks and a 6-week to baseline ratio of >1.419 for mean PFV blur. 28,29 In the trial that evaluated the effectiveness of base-in prism reading glasses prescribed according to Sheard's criterion (convergence … Methods—In a randomized clinical trial, 221 children 9 to 17 years with symptomatic CI were assigned to one of four treatments. 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. [3] A more recent trial completed by the Pediatric Eye Disease Investigator Group (PEDIG) evaluated the effectiveness of a home-based therapy and suggested that the home-based therapy alone had a less successful outcome compared to treatment that included in-office visits; however, recruitment was an i… The baseline data reported herein define the clinical profile of those enrolled into the CITT. The task remains constant, but the nature of the procedure changes with time: Pairwise treatment group comparison (HB-C versus HB-PU) 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 (Type I error rate = 2.5%). Cochrane Database Syst Rev. Thus, the Convergence Insufficiency Treatment Trial - Attention & Reading Trial (CITT-ART) was designed as a prospective randomized trial to determine whether reading and attention improve in school- Active home-based computer therapy will be provided the Home Therapy System (HTS) computer software and will include both fusional vergence and accommodative therapy. 3099067 PMID 18852411 6. Randot Preschool stereoacuity of at least 400 seconds of arc, No use of a plus add for near or base-in prism for at least 2 weeks preceding enrollment, Myopia more than -0.75D spherical equivalent (SE) in either eye, Hyperopia more than +2.00D SE in either eye. For hyperopia, the spherical component can be reduced by up to 1.50D at investigator discretion provided the reduction is symmetrical and results in residual (i.e., uncorrected) SE hyperopia that does not exceed +2.00D. N2 - Objective: This report describes the design and methodology of the Convergence Insufficiency Treatment Trial (CITT), the first large-scale, placebo-controlled, randomized clinical trial evaluating treatments for convergence insufficiency (CI) in children. Researchers evaluated the accommodative function of patients with symptomatic convergence insufficiency and coexisting accommodative dysfunction who underwent vergence/accommodative therapy. 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. 2008; 15(1):24-36 (ISSN: 1744-5086).

At a Pediatric Eye Disease Investigator Group (PEDIG) meeting (Tampa, January 2009), the results of a poll of attendees indicated that a large majority of pediatric ophthalmologists continue to recommend home-based near target push-ups as the initial treatment approach for children with symptomatic CI in spite of the CITT results. 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. Addressing some of the limitations of previous studies, the Convergence Insufficiency Treatment Trial Investigator Group conducted a pilot study to evaluate the impact of vergence/accommodative therapy on reading performance in children with symptomatic convergence insufficiency. Convergence Insufficiency Treatment Trial–trained and –certified ophthalmologists or optometrists performed all testing using a previously described standardized protocol. Due to sample size considerations, it was not feasible to compare the HB-PU group with the HB-P group as a primary outcome pairwise comparison based on the assumed successful outcome percentages of 15% vs. 10%. Convergence Insufficiency Treatment Trial Study Group. Figure 2 outlines the treatment sequence. The NEI Convergence Insufficiency Treatment Trial (CITT) has shown that the most effective treatment for CI is in-office therapy, overseen by a trained therapist, with additional at-home exercises. It is to be administered before any other clinical testing. The Convergence Insufficiency Treatment Trial (CITT) Investigator group was first conceived in December 1992 at the annual meeting of the American Academy of Optometry. Success is based on the mean NPC (near point of convergence) break is defined as having a mean NPC break of <6 cm at 12 weeks and a 12-week to baseline ratio of <0.763 for mean NPC break.

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. Vision therapy for CI is based upon the protocol set by the Convergence Insufficiency Treatment Trial (CITT), and consists of office-based vergence/accommodative therapy with home reinforcement. Astigmatism cylinder must be within 0.50D of full correction and axis must be within 5 degrees. Procedure 1. Clinical success is defined according to whether both criteria (below) are met as follows: Improvement in all 3 outcome measures at 12 weeks will be defined as follows: (Note: All 3 criteria must be met in order to be classified as an "improver" at the 12-week primary outcome visit). Registered in England & Wales No. With the pencil positioned at arm's length directly between the subject's eyes, the subject will slowly bring the pencil toward his/her nose while focusing on the small letter on the pencil. At that time the group used the acronym CIRS (Convergence Insufficiency Reading Study). N2 - Objective: This report describes the design and methodology of the Convergence Insufficiency Treatment Trial (CITT), the first large-scale, placebo-controlled, randomized clinical trial evaluating treatments for convergence insufficiency (CI) in children. 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. 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. 5. Identification of the most effective treatment regimen is important because of the high prevalence of this binocular vision disorder and its potential effect on reading and other near visual activities. 5. At enrollment, subjects will be prescribed 15 minutes/day (3 sessions of 5 minutes each) of near target push-ups (NTP) for 5 days/week during the 12-week treatment phase.
