Office-based Vision Therapy for Improving Reading and Attention in Children With Convergence Insufficiency...

Convergence Insufficiency

CITT-ART is a multicenter study (8 locations around the United States) of 324 children ages 9 to <14 years with symptomatic convergence insufficiency (CI). The purpose of this study is to see if office-based therapy for convergence insufficiency (CI) improves reading ability and attention. CI is an eye-teaming problem where the eyes would like to drift outward when reading or doing close work. When eyes drift out, double vision can happen. To prevent double vision one must use extra effort to keep the eyes from going out. This extra effort can cause symptoms that can interfere with reading and working comfortably at near. These symptoms often include eyestrain, blurred vision, headaches, double vision, and loss of place when reading or performing tasks at near. In a prior study we found that therapy improves these symptoms. In this study we are looking at whether the therapy improves reading and attention

Comparison of Three Vision Therapy Approaches for Convergence Insufficiency

Comparison of Three Vision Therapy Approaches for Convergence Insufficiency

We compared the effectiveness of three active vision therapy approaches for convergence insufficiency (CI). Patients with eligible criteria and symptomatic CI were included in a prospective study and randomly allocated into three groups. In the home-based vision orthoptic therapy (HBVOT) group, patients were trained to do the pencil push-ups procedure 15 minutes per day, five days a week. In the office-based vision orthoptic therapy (OBVOT) group, 60 minutes of orthoptic therapy using a major amblyoscope twice weekly with additional home orthoptic therapy was prescribed. For the augmented office-based vision orthoptic therapy (AOBVOT) group, orthoptic exercises using three diopter over-minus lenses and a base out prism, in addition to major amblyoscope and additional home reinforcement was prescribed in the same period of time.

Objective Assessment of Disparity Vergence After Treatment of Symptomatic CI in Children

Convergence Insufficiency

This study is designed to evaluate changes in objective measures of disparity vergence after office-based vergence/accommodative therapy (OBVAT) for convergence insufficiency (CI) in children 12-17 years old.

Eyetracking and Neurovision Rehabilitation of Oculomotor Dysfunction in Mild Traumatic Brain Injury...

Mild Traumatic Brain InjuryBrain Concussion4 more

The purpose of this single center, longitudinal, pilot study is to provide evidence for the use of an eye tracking system as an objective tool to identify mild traumatic brain injury (mTBI) related oculomotor dysfunction (OMD) and predict the effectiveness of neurovision rehabilitation (NVR) of OMD. Eye tracking visual stimulus measurements will be compared to objective developmental optometrist (OD) diagnosis and assessments. It will be determined whether an eye tracking system can predict the presence or absence of mTBI related OMD and whether mTBI patients who have OMD based on the eye tracking system will respond positively to NVR.

Study of Eyes and Attention Deficit (SEAD)

ADHDConvergence Insufficiency1 more

Attention-Deficit Hyperactivity Disorder (ADHD) is considered to be one of the most prevalent chronic health conditions in children. It affects between 4% and 12% of young children. A relationship between convergence insufficiency (eye teaming) and ADHD has been shown. However, the effect of ADHD medications on focusing and eye teaming has not been previously investigated. Therefore, the purpose of this study is to determine the effect of ADHD medication on focusing and eye teaming skills.

Study of Cytokines in Children With Opsoclonus-Myoclonus Syndrome

Opsoclonus-myoclonus Syndrome

The purpose of this study is to determine if cytokines, inflammatory mediators, are increased in spinal fluid and blood, correlate with disease activity, and could serve as biomarkers or therapeutic targets in children with opsoclonus-myoclonus syndrome (OMS), an autoimmune complication of the tumor neuroblastoma.

Screening for Convergence Insufficiency in School-age Children

Convergence Insufficiency

The purpose of this study was to assess the ability of common tests of eye alignment, convergence, and accommodation to identify children with convergence insufficiency in a school screening setting.

Eye Movement and Cognitive Dysfunction

Eye Movement DisorderCognitive Dysfunction

There is association between eye movement disorder and cognitive dysfunction. Therefore, utilizing eye movement and screening for cognitive dysfunction is feasible. In the present study, we will develop an artificial intelligence platform to screening for cognitive dysfunction by inspecting the function of eye movement. Futher more, based on the screening results, the platform will offer referral suggestions.
