11 Clinical Trials for Various Conditions
Intermittent exotropia is difficult to treat. The mainstay of treatment involves surgery, and in one long-term study authors found that as many as 60% of IXT required at least one re-operation.Patching of the non-dominant eye has also been tested in a large, multi-center randomized control trial and was not found to have a large benefit. More non-surgical treatment modalities are critical to improve the care in this condition.
The objective of this short-term, pilot randomized trial comparing spectacles with relieving prism to spectacles without prism is to determine whether to proceed to a full-scale, longer-term randomized trial. This decision will be based primarily on assessing the initial (8-week) response to prism by comparing treatment groups on the following outcomes: * Mean distance intermittent exotropia (IXT) control score (the mean of 3 control scores) (primary outcome) * The proportion of participants demonstrating a "treatment response," defined as ≥1 point improvement in the mean distance IXT control score without spontaneous exotropia during control testing (secondary outcome) * The proportion of participants reporting adverse effects and good/excellent spectacle wear compliance
Determine whether full-time patching is more effective than observation for improving distance control of IXT after 3 months of treatment (on-treatment outcome).
The main objective of this randomized trial comparing vision therapy to observation is to determine the short-term effectiveness of vision therapy on distance intermittent exotropia control. The results will help determine whether to proceed to a full-scale, long-term randomized trial.
Aim 1: To determine whether use of dichoptic movies for 4 weeks may be helpful in improving control of alignment in children with intermittent exotropia (IXT), thus allowing IXT to be managed non-surgically Aim 2: To determine pre-IXT surgery use of dichoptic movies for 4 weeks post-operatively may be helpful in maintaining successful control of alignment in children who have surgical correction of IXT
This study presents an opportunity to understand a novel, previously unreported controlled intermittent alternate occlusion (CIAO) therapy glasses, which may improve the control of Intermittent exotropia (IXT).
The main objectives of this randomized trial comparing overminus lens treatment to non-overminus (spectacles without overminus or spectacles with plano lenses) are to determine: * The long-term on-treatment effect of overminus treatment on distance intermittent exotropia (IXT) control score. * The off-treatment effect of overminus treatment on distance IXT control score (following weaning and 3 months off treatment).
To determine the effectiveness of alternate occlusion therapy for the treatment of IXT among patients aged 3 to \< 11 years old.
The objective of this short-term, pilot randomized trial comparing 2.50 diopters (D) overminus lens treatment vs. non-overminus (spectacles without overminus or no spectacles) in children with intermittent exotropia (IXT) 3 to \<7 years of age is to determine whether to proceed to a full-scale, longer-term randomized trial.
The purpose of this study is to evaluate the effectiveness of bilateral lateral rectus muscle recession versus unilateral lateral rectus recession with medial rectus resection procedures for the treatment of basic type and pseudo divergence excess type intermittent exotropia.
The present study is being conducted to assess the natural history of intermittent exotropia and to establish the effectiveness of occlusion in its treatment. Study Objectives: * To determine the effectiveness of occlusion for the treatment of intermittent exotropia among patients aged 3 to \< 11 years who have baseline near stereoacuity of 400 arcsec or better by Preschool Randot stereotest * To determine the natural history of intermittent exotropia among patients aged 3 to \< 11 years who have baseline near stereoacuity of 400 arcsec or better by Preschool Randot stereotest
