The assumed success percentages were determined based on the Convergence Insufficiency Treatment Trial (CITT) 14 and clinical expertise. 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). Mark Boas§, Rachel Coulter*, Kristine Hopkins¶, Susanna Tamkins**; The Convergence Insufficiency Treatment Trial Study Group ABSTRACT Purpose. We also report the clinical and demographic characteristics of patients. By closing this message, you are consenting to our use of cookies. Success is based on the mean PFV (positive fusional vergence) blur, defined as having a mean PFV blur of >15 pd at 12 weeks and a 12-week to baseline ratio of >1.419 for mean PFV blur. 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. Please refer to the procedures manual for further details. 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. We also report the clinical and demographic characteristics of patients. 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). Harrison RL. 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. The parents were instructed to regularly supervise and ensure that their child was carrying out the procedure correctly. 34 Eligible patients who consented to participate were enrolled in the study, and the measures taken at their eligibility examination were used as the study baseline measures. 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. COVID-19 is an emerging, rapidly evolving situation. Subjects will perform the computer therapy while wearing red/blue glasses and accommodative therapy will be performed using the HTS accommodative flippers. 2019 Nov;96(11):825-835. doi: 10.1097/OPX.0000000000001443. CITS Procedures Manual v 5.0 3-4-14 Table of Contents CONVERGENCE INSUFFICIENCY SYMPTOM SURVEY (CISS) ADMINISTRATION ... the next trial. Study record managers: refer to the Data Element Definitions if submitting registration or results information. Relocation outside of area of an active PEDIG site within the next 15 months is not anticipated. Registered in England & Wales No. Please refer to the procedures manual for further details. A prospective clinical trial is therefore needed to determine the effectiveness of home-based computer therapy for symptomatic CI compared to traditional home-based near target push-ups and placebo treatment. Patient must be wearing appropriate refractive correction (spectacle or contact lenses) for at least 2 weeks prior to enrollment if refractive error is present (based on a cycloplegic refraction within the last 6 months) that meets the following: To learn more about this study, you or your doctor may contact the study research staff using the contact information provided by the sponsor. 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. A combination of in-office and at-home orthoptics and vision therapy probably represents the best therapeutic approach for convergence insufficiency. 2020 Dec 2;12:CD006768. In preparation for our randomized clinical trial, the Convergence Insufficiency Treatment Trial (CITT) Study Group completed 2 pilot studies that were placebo-controlled, randomized trials investigating the effectiveness of passive and active treatments for symptomatic CI in children. Outcome data on the Convergence Insufficiency Symptom Survey (CISS) score (primary outcome), near point of convergence (NPC), and positive fusional vergence were collected after 12 weeks of active treatment and again at 6 and 12 months posttreatment. 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. 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. 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 who are classified as a success based on the mean NPC break at the 6-week visit. Methods: We prospectively randomized children 9 to 17 years of age to one of four treatment groups: 1) home-based pencil push-ups, 2) home-based computer vergence/accommodative therapy and pencil push-ups, 3) office-based vergence/accommodative therapy with home reinforcement, 4) office-based placebo therapy. tomatic convergence insufficiency. Ophthalmic Epidemiol. Convergence Insufficiency Treatment Trial–trained and –certified ophthalmologists or optometrists performed all testing using a previously described standardized protocol. 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. Long-term effectiveness of treatments for sympto- Methods—In a randomized clinical trial, 221 children 9 to 17 years with symptomatic CI were assigned to one of four treatments. Please refer to this study by its ClinicalTrials.gov identifier (NCT number): NCT01515943. 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%). K. Patricia Bouweraerts, MA. Subjects will be prescribed 5 minutes/day of placebo yoked prism flipper therapy for 5 days/week during the 12 week treatment phase. PMID 18852411 6. This treatment sequence is a wellaccepted approach for treatment of convergence insufficiency and has been successfully implemented in previous randomized clinical trials … 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. 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. When the subject is no longer able to maintain a single image of the pencil, he/she will slowly move the target away from the nose until the pencil becomes single again. Previous CITT Study. 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. He accepts all insurances and Medicaid. The baseline data reported herein define the clinical profile of those enrolled into the CITT. The number of subjects who are classified as a success based on the mean NPC break at the 12-week visit. [ 30, 35] Follow-up depends on the severity … PMID 18852411 6.
