The number of subjects classified as a success based on signs/symptoms at the 6-week visit. protocols (some studies measure near point of convergence with a pencil, whereas others use an accommodative target that may alter measurements). Most children given in-office therapy showed normal vision or significant improvement in symptoms after 12 weeks. adult patients (ages 19–30 years) using the identical protocol. Please refer to the procedures manual for further details. He accepts all insurances and Medicaid. The Convergence Insufficiency Treatment Trial (CITT) study groupdesignedthispilotstudyinpreparationforalargerrandom-ized clinical trial. Active treatment: A multi-site randomized clinical trial funded by the National Eye Institute has proven that the best treatment for convergence insufficiency is supervised vision therapy in a clinical office with home reinforcement (15 minutes of prescribed vision exercises done in … 5. Methods. PFV is recorded as the prism magnitude where vision is first blurred (or break if no blur is reported). tomatic convergence insufficiency. 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. Reduced positive fusional convergence at near (<20 pd or fails Sheard's criterion that the PFV measures less than twice the magnitude of the near phoria). PMID 18852411 6. Subjects will be prescribed 5 minutes/day of placebo yoked prism flipper therapy for 5 days/week during the 12 week treatment phase. This study was a masked, placebo-controlled, multicenter,randomizedclinicaltrialinwhichyoungadults19to In 2005, the Convergence Insufficiency Treatment Trial (CITT) published two randomized clinical studies. Methods: In a randomized clinical trial, 221 children aged 9 to 17 years with symptomatic convergence insuf-ficiency were assigned to 1 of 4 treatments. Study Chair: CITT-ART: Convergence Insufficiency Reading and Attention Treatment Trial (CITT) NEI funded, May 2014 – April 2019; Co-Protocol Chair: Convergence Insufficiency Treatment Study (CITS) 2012-present; Study Chair: Convergence Insufficiency Treatment Trial (CITT) NEI sponsored, October 2004 – September 2008 An evaluation of clinical treatment of convergence insufficiency for children with reading difficulties ... choose either treatment option. Previous CITT Study. Parent has home phone (or access to phone) and is willing to be contacted by Jaeb Center staff. The treatment sequence used in this study was modified from the treatment protocol previously used in the Convergence Insufficiency Treatment Trial randomized clinical trial. 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. Relocation outside of area of an active PEDIG site within the next 15 months is not anticipated. The assumed success percentages were determined based on the Convergence Insufficiency Treatment Trial (CITT) 14 and clinical expertise. 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. We also report the clinical and demographic characteristics of patients. Gallaway was also the Principal Investigator at Salus University for the Convergence Insufficiency Treatment Trial (CITT), an NIH funded randomized multicenter clinical trial … NEW: Convergence Insufficiency Treatment Trial - Attention and Reading Study (CITT-ART) Participants Needed for new CITT-ART study. The Convergence Insufficiency Treatment Trial (CITT) Study Group. Active treatment: A multi-site randomized clinical trial funded by the National Eye Institute called the Convergence Insufficiency Treatment Trial showed: The best treatment for CI is supervised vision therapy in a clinical office with home reinforcement (15 minutes of prescribed vision exercises done in the home five days per week). To be considered an overall success, each of the following criteria must be met for the 3 outcome measures at 6 weeks: (Note: All 3 criteria must be met in order to be classified as an overall success at the 6-week visit). The number of subjects who are classified as a success based on the mean PFV blur at the 12-week visit. 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. Main Outcome Measures: Convergence Insuffi-ciency Symptom Survey score after 12 weeks of treat-ment. 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. 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%). A complete pediatric eye exam with cycloplegic dilation i… R. John Leigh and David S. Zee. A Study of Clinical Characteristics, Treatments, and One-Year Outcomes of Adults with Strabismus Rochester, MN . The study had well-defined eligibility criteria, a standardized treatment protocol administered by trained therapists, and … Convergence Insufficiency Treatment Trial Study Group. The purpose of this study is to describe clinical characteristics, treatments, and one-year outcomes for adults who have convergence insufficiency, divergence insufficiency… 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. 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. 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. PMID 18852411 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. Arch Ophthalmol. cific CITT protocol from the manual of procedures, which de-scribed the proper treatment technique, amount of time the techniquewastobeused,expectedperformance,andcriteriafor ending the procedure and advancing to a more difficult level. There are significant differences in contact time, complexity, and cost between office-based and home-based therapy for CI. 5. Active treatment: A multi-site randomized clinical trial funded by the National Eye Institute has proven that the best treatment for convergence insufficiency is supervised vision therapy in a clinical office with home reinforcement (15 minutes of prescribed vision exercises done in … Convergence Insufficiency Treatment Trial (CITT) Study Group. This procedure will be repeated several times. Parent and patient understand the protocol and are willing to accept randomization. After treatment for convergence insufficiency, statistically significant improvements were found for reading comprehension (mean = 4.2, p = 0.009) and the reading composite score (mean = 2.4, p = 0.016) as measured by the Wechsler Individual Achievement Test at the 24‐week visit. 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.
