Study Summary

This trial uses psychophysical measures to study neural plasticity in both adults and children with amblyopia, a developmental abnormality that impairs spatial vision and is a major cause of vision loss.

Who is the study for?

This trial is for both adults and children who have normal vision or amblyopia, commonly known as 'lazy eye', where there's a noticeable difference in visual sharpness between the eyes. People with any eye diseases or involuntary eye movement (nystagmus) cannot participate.Check my eligibility

What is being tested?

The study is testing new treatments for lazy eye by using video game vision training, perceptual learning exercises, and traditional occlusion therapy which involves covering the stronger eye to improve the weaker one.See study design

What are the potential side effects?

While not explicitly stated, potential side effects may include eyestrain, headaches, or dizziness from intensive visual tasks. Traditional occlusion therapy might cause discomfort from wearing an eye patch.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.

Primary outcome measures

Change in positional (or Vernier) acuity before and after the intervention

Trial Design

3Treatment groups

Experimental Treatment

Active Control

Group I: Video GamesExperimental Treatment1 Intervention

Participants will be required to play video games for a period of time: 1-2 hrs per session, 4-5 sessions/week for ~1-6 months

Group II: Perceptual learningExperimental Treatment1 Intervention

Participants will be required to practice a visual discrimination task (e.g. visual acuity, position acuity, contrast sensitivity, & stereoacuity) for a period of time: 1-2 hrs per session, 4-5 sessions/week for ~1-6 months

Group III: Occlusion therapyActive Control1 Intervention

Participants will be required to cover the dominant eye during the day in order to push the brain to use the fellow amblyopic eye: 1-2 hrs per session, 4-5 sessions/week for ~1-6 months

Why did patients apply to this trial?

I have tried many options in hoping something will help. I want to help speed up the process of research in this field. I want to find out if it's possible to get rid of this condition completely in adulthoood.

PatientReceived 1 prior treatment

I have applied a decent job but disquialified because of amblyopia, then i found that i have this disease and learnt that this not curable at the moment. it is my pleasure if you.

PatientReceived no prior treatments
