Filter by:To understand the benefits of the neurolens Measurement Device and neurolens treatment as it pertains to treating symptoms related to Chronic Headaches. It is a Prospective randomized double masked two arm performed on a minimum of 200 to a maximum of 300 subjects identified as symptomatic (HIT-6 questionnaire score equal to or greater than 56) done across 3-15 clinical sites. There are two subgroups: a minimum of 100 in each subgroup (subgroup 1: pre-presbyopic (18-40 years); subgroup 2: presbyopic subjects (41-60 years).
Convergence insufficiency (CI) is a prevalent binocular vision disorder with symptoms that include double/blurred vision, eyestrain, and headaches when engaged in reading or other near work. CI is present in 4% of the population where approximately 27% of CI patients do not improve even with validated therapy. The project will quantitatively study changes in convergence eye movements and neural substrates before and after validated therapy in CI patients. This knowledge can lead to improvements in currently validated therapy, reduction in therapy sessions, and reduced healthcare costs.
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.
The Baltimore Reading and Eye Disease Study (BREDS) is a two year study to determine the prevalence of vision problems in an early school age population with reading difficulty. Comprehensive vision and reading tests will be administered to 400 students at participating schools in the Baltimore City Public School system. A secondary goal is to examine the impact of vision treatment on reading performance. Children with refractive error or convergence insufficiency will be provided treatment free of charge. The investigators will evaluate the impact that the treatment has on vision function and reading performance.
The purpose of this study is to describe clinical characteristics, treatments, and one-year outcomes of adults with convergence insufficiency, divergence insufficiency, or small angle hypertropia.
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.
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.
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.
The Convergence Insufficiency Treatment Trial (CITT) is a multi-center, placebo-controlled, single-masked, clinical trial designed to compare the benefits of two commonly used treatment approaches for patients with convergence insufficiency (CI)
This study is designed to compare the use of special prism glasses to placebo treatment for children with symptomatic convergence insufficiency.
