Filter by:Objective: Prospective evaluation of GoCheckKids™, a smartphone application ('App') as a photo screening device in a pediatric population to detect amblyopia risk factors (ARFs) Method: Photorefraction images are captured using up to 4 different devices with GoCheckKids™ App and patients are evaluated with cycloplegic refraction.
The research deals with amblyopia or lazy eye, a condition that affects about 3% of the population, and results in a variety of visual deficits. Recent work suggests that there is limited neural plasticity in the visual system of adults with amblyopia. This study is aimed at understanding and increasing this plasticity. In this study, the investigators aim to understand how the amblyopic brain learns and how this process is affected by a drug called donepezil, which is sometimes given as a treatment for Alzheimer's disease. The investigators hope that this study will help to identify the chemical components that help the brain to learn, as well as the mechanism of amblyopia. The investigators also plan to test the normal periphery, as control.
This is a study to investigate efficacy of over-glasses patch treatment for amblyopic children using visual function improvement and Amblyopia Treatment Index (ATI) changes.
Contrast balanced dichoptic videogame training has been found to improve sensory functions in adults with amblyopia; best corrected distance visual acuity (BCVA) and stereopsis, but its effect on motor function, namely amblyopic eye fixation stability, is unknown. Furthermore, the effect of treatment in cases of mild amblyopia is not well understood. The aim of this study is to find out the difference on fixation stability, BCVA and stereopsis in mild amblyopes after 6 weeks' contrast balanced dichoptic video game training.
To compare the efficacy of 1 hour/day of binocular game play 5 days per week plus spectacle correction with spectacle correction only, for treatment of amblyopia in children 4 to <13 years of age.
To evaluate the efficacy and safety of Eyetronix Flicker Glassess therapy in treating anisometropic amblyopia.
The validation of a French questionnaire is very important to assess rigorously and objectively the impact of the treatments of strabismus and amblyopia on children quality of life.
Around one child in fifty has a lazy eye (termed amblyopia) where the eye is structurally normal but the vision fails to develop correctly. Around half of these children also have a squint (strabismus) where each eye has a different direction of gaze. This condition is the commonest cause of visual impairment in one eye in children. This is a randomised control trial of wearing glasses alone (which will result in some visual improvement, termed refractive adaptation) and wearing glasses combined with using I-BiT Plus. The hypothesis is that using I-BiT Plus will result in an improved visual outcome.
Amblyopia is a significant health problem, affecting up to 4% of the population in the United States. Amblyopia, commonly known as "lazy eye," is a developmental visual disorder in which one or both eyes suffer from poor vision as a result of being disadvantaged in early life. Strabismus, or eye misalignment, such as crossed eyes (esotropia) or wandering eyes (exotropia), and anisometropia, or a power difference between the eyes, are the most common causes of amblyopia. If conventional treatment, such as patching the better seeing eye, is not initiated during the critical period of visual development, lasting visual impairment may persist throughout life. This critical period of visual development has been thought to end around age 10. However, recent research has demonstrated that the critical period of visual development can be extended into adulthood. Complete light deprivation in animal models has restored plasticity in the visual cortex and has demonstrated drastic recovery of vision in amblyopic eyes. The objective of this pilot study is to evaluate the impact of complete light deprivation on visual function in a cohort of human adults with severe amblyopia from anisometropia.
A single-arm, multi-center, open-label pilot study to evaluate the feasibility, safety, and efficacy of the Luminopia One digital therapeutic in improving visual acuity in a pediatric amblyopia population.
