Figure 2 outlines the treatment sequence. 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. 2008; 15(1):24-36 (ISSN: 1744-5086). PFV is recorded as the prism magnitude where vision is first blurred (or break if no blur is reported). 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- 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. 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. Mark Boas§, Rachel Coulter*, Kristine Hopkins¶, Susanna Tamkins**; The Convergence Insufficiency Treatment Trial Study Group ABSTRACT Purpose. While the home-based therapies in the CITT were not as effective as office-based vergence/accommodative therapy there was some improvement noted. Optom Vis Sci. Convergence insufficiency treatment trial (CITT) Convergence insufficiency can only be detected and diagnosed during an eye examination, said principal investigator of the CITT, Prof Mitchell Scheiman, O.D., Chief, Pediatric Binocular Vision Service at The Eye Institute of … 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 … There are significant differences in contact time, complexity, and cost between office-based and home-based therapy for CI. He is a graduate of Indiana University where he completed a residency in binocular vision and pediatrics. Scheiman M, Kulp MT, Cotter SA, Lawrenson JG, Wang L, Li T. Interventions for convergence insufficiency: a network meta-analysis. CONVERGENCE INSUFFICIENCY TREATMENT STUDY (CITS) PROCEDURES MANUAL Version 5.0 March 4, 2014 . Harrison RL. 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. tomatic convergence insufficiency. We also report the clinical and demographic characteristics of patients. Ophthalmic Epidemiol. The vergence procedures are similar to the active version, however, the tasks will be modified to ensure no demand on the vergence system and no accommodative therapy is included in the placebo version. Convergence Insufficiency Treatment Trial Study Group. 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. The number of subjects classified as a success based on signs/symptoms at the 6-week visit. 33 In addition to the accommodative and near vergence techniques from the original protocol, distance vergence, oculomotor and anti-suppression were incorporated. 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.
