Patching or Gaming as Amblyopia Treatment?

2018-12-13 02:49:11 | BioPortfolio

Summary

Amblyopia affects 3% of the children and is caused by strabismus, anisometropia or both. Standard treatment is glasses and patching therapy. From North-America, behavioural training, i.e. dichoptic training, perceptual learning and video gaming, has become increasingly popular to improve visual acuity not only in children but also in adults. In this study we aim to compare the standard occlusion therapy with dichoptic video gaming.

Description

Amblyopia affects 3% of the children and is caused by strabismus, anisometropia or both. The standard treatment is glasses and patching therapy. From North-America, behavioural training, i.e. dichoptic training, perceptual learning and video gaming, has become increasingly popular. The rationale behind these games is by using dichoptic stimulation, with the contrast of the stimuli presented to the good eye reduced to match the appearance of the same stimuli when shown to the amblyopic eye, suppression can be alleviated. The many studies now conducted, demonstrate improvement in visual acuity with the games, the effect however is limited, but the rate of improvement is higher. In these studies, prescribed patching-time was compared to realised game-time. We have demonstrated in multiple studies that electronically measured compliance is low: on average only 50%.

In this study we aim to compare the effect of patching therapy, using the ODM to objectively measure compliance, with the effect of a novel dichoptic action video game in children as well as in adults. In addition, the adult participants will undergo fMRI scans to document any changes in the visual cortex before and after either therapy.

Will Perceptual Learning Via Video Game Playing Improve Visual Acuity Stereopsis & Fixation Stability in Mild Amblyopes?

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 ef...

Dichoptic Video Treatment for Amblyopia

Treating Amblyopia in Adults With Interactive Video Games

Researchers are trying to determine whether interactive video game play, while wearing a patch over better-seeing eye, will improve subject reduced vision (amblyopia).

Electronic Recording of Compliance With Occlusion Therapy for Amblyopia

The purpose of this study was to determine whether compliance with occlusion therapy for amblyopia could be improved and, secondly, if risk factors for non-compliance could be identified.

Virtual Reality Game Playing in Amblyopia Therapy

Background: "Amblyopia is a neurodevelopmental disorder in both monocular and binocular functions and it extends even beyond the primary visual integration centers", therefore, amblyopia i...

Levodopa Plus Occlusion Therapy versus Occlusion Therapy Alone for Children with Anisometropic Amblyopia.

This study aimed to compare the effects of short-term administration of levodopa plus occlusion therapy versus occlusion therapy alone in preschool children with hyperopic anisometropic amblyopia.

Dichoptic De-Masking Learning in Adults With Amblyopia and Its Mechanisms.

Recently, we reported that dichoptic de-masking training can further boost stereoacuity, but not visual acuity, in adults with amblyopia after extensive monocular perceptual training. Here, we investi...

Video game use among secondary school students and associated factors.

Abnormal Monocular and Dichoptic Temporal Synchrony in Adults with Amblyopia.

We investigate temporal synchrony within one eye and between both eyes in adults with amblyopia.

Eye Conditions in Infants and Children: Amblyopia and Strabismus.

Amblyopia is a developmental disorder of the central nervous system. It occurs in infancy or early childhood when the visual system is susceptible to issues that interrupt development. In the United S...

Medical and Biotech [MESH] Definitions

Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.

A nonspecific term referring to impaired vision. Major subcategories include stimulus deprivation-induced amblyopia and toxic amblyopia. Stimulus deprivation-induced amblyopia is a developmental disorder of the visual cortex. A discrepancy between visual information received by the visual cortex from each eye results in abnormal cortical development. STRABISMUS and REFRACTIVE ERRORS may cause this condition. Toxic amblyopia is a disorder of the OPTIC NERVE which is associated with ALCOHOLISM, tobacco SMOKING, and other toxins and as an adverse effect of the use of some medications.

A therapeutic approach, involving chemotherapy, radiation therapy, or surgery, after initial regimens have failed to lead to improvement in a patient's condition. Salvage therapy is most often used for neoplastic diseases.

Drug therapy given to augment or stimulate some other form of treatment such as surgery or radiation therapy. Adjuvant chemotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.

The use of art as an adjunctive therapy in the treatment of neurological, mental, or behavioral disorders.
