Dichoptic Video Amblyopia Treatment Contrast Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for amblyopia, such as patching and penalization, suffer from poor compliance and may compromise binocular visual development, and existing therapies only partially restore stereoacuity in a significant portion of patients, leaving deficiencies in depth perception unresolved.
Innovation Solution
A method and system for generating and presenting dichoptic video content, where specific target features are made more visible to one eye and background features are suppressed, using anaglyph glasses to improve stereoacuity by adjusting contrast and color characteristics based on individual contrast testing data, ensuring the non-dominant eye is stimulated more prominently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If patching and penalization are used for amblyopia treatment, then visual acuity may be improved, but compliance is poor and binocular visual development is compromised
Solution Approach 1:
The patent transforms traditional amblyopia treatment by changing the parameters of visual stimulation from uniform high-contrast images to dichoptic images with different contrast levels for each eye. The system presents high-contrast images to the amblyopic eye and low-contrast images to the sound eye, creating a parameter difference that drives binocular development while maintaining patient compliance through engaging video content.
2Measurement precision
If traditional therapies are used for amblyopia, then some visual improvement is achieved, but stereoacuity is only partially restored in 15-54% of patients
Solution Approach 1:
The patent applies local quality by presenting different image qualities to different eyes simultaneously. The amblyopic eye receives high-contrast images optimized for its reduced visual acuity, while the sound eye receives low-contrast images. This localized differentiation allows each eye to be stimulated at its optimal level, promoting both visual acuity improvement and stereoacuity development.
Solution Approach 2:
The system dynamically adjusts the contrast characteristics of images presented to each eye based on the patient's specific amblyopia severity and progression. The dichoptic video content can be modified in real-time or across treatment sessions to optimize the contrast difference between eyes, making the therapy adaptive rather than static.
3Reliability
If dichoptic video presentation is implemented, then stereoacuity and visual acuity are significantly improved, but the system complexity increases
Solution Approach 1:
The patent introduces a video processing system as an intermediary that automatically generates dichoptic video content from standard video sources. This intermediary system handles the complex task of separating image content into high-contrast and low-contrast portions for each eye, eliminating the need for manual image creation and reducing the technical burden on clinicians while maintaining therapeutic effectiveness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The approach significantly improves stereoacuity and visual acuity in patients with amblyopia, with clinical and statistical significance observed even after discontinuation of the video program, demonstrating potential for enhanced visual system development beyond standard therapies.
Implementation Method 1
presenting the first portion of the moving images in first one or more colors that are visible through a first filtering lens configured to inhibit visibility of second one or more colors, and presenting the second portion of the moving images in the second one or more colors that are visible through a second filtering lens configured to inhibit visibility of the first one or more colors

AI summary
Disclosed are implementations, including a method for video presentation to cause controllable stimulation of a subject's eyes, that includes preparing a video presentation comprising successive frames of moving images, and, for one or more of the successive frames, selecting a target feature(s) represented in the moving images, with the moving images further comprising one or more background features, the target feature causing stimulation of one of a first eye or a second eye of the subject. For at least some of the frames in which the target feature(s) appears, the method also includes controlling a first contrast characteristic of the target feature(s) to form a first portion of the moving images, and controlling a second contrast characteristic of the one or more background features to form a second portion of the moving images. The method further includes providing the prepared video presentation.
