Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Amblyopia is a visual neurodevelopmental disorder associated, more frequently, with the presence of strabismus and anisometropia. It is clinically most important visual condition in childhood because, apart from refractive error, it is the most frequent cause of vision loss in children. It is a reversible condition that affects up to 5% of the population, and that is the result of an abnormal visual experience during the most sensitive period of visual development. Although amblyopia is expressed in the clinical practice as a reduction in visual acuity, it is also characterized by an altered stereoscopy. Generally, treatments for amblyopia focus on the recovery of visual acuity, and there are no treatments that focus mainly on the recovery of the altered stereopsis, so present and with an important functional impact.

The aim of this study reviewing, analyzing and, if applicable, updating the current treatment model for amblyopia. On the one hand, to evaluate the effectiveness of viewing a 3D movie in the improvement of stereoacuity and the deviation, as well as visual acuity and sensitivity to contrast. Also, the correlation between them. On the other hand, to assess quantitatively the degree of satisfaction and acceptance of the participants and their families towards the intervention.

A quasi-experimental study will be performed, without a control group, pre- and post- intervention in which subjects with refractive and / or strabismus amblyopia, that have been subjected to traditional treatment for amblyopia, will be selected. Variables of stereopsis, latent or manifest deviation, visual acuity and sensitivity to the contrast will evaluate previously and after the intervention.

The sample will include subjects between 5 to 12 years old with a diagnosis of refractive and / or strabismic amblyopia.
