Effect of 3D Movie Viewing on Stereopsis in Strabismus & / or

Status Completed

Clinical Trial Summary

This study evaluates the effect of 3D movie viewing on stereopsis recovery in anisometropic and / or strabismus amblyopia and the satisfaction with the intervention.

Clinical Trial Description

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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
