Dichoptic Display Therapy for Amblyopia Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for amblyopia, such as patching, do not effectively address the suppression of the amblyopic eye by the fellow eye, leading to inadequate binocular vision and limited treatment efficacy, and existing methods for assessing and treating binocular vision deficiencies are either passive or lack quantitative measurement.
Innovation Solution
A method and apparatus that utilize a signal/noise paradigm to assess and treat binocular vision by presenting different information content to each eye, allowing for quantitative measurement of interocular suppression and gradual adjustment to achieve balanced binocular performance, using a dichoptic display system to present variable differences in image content to the two eyes, and a handheld device for portable therapy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If patching or penalizing the fellow eye is used to treat amblyopia, then monocular function of the amblyopic eye is improved, but binocular function is not restored and the treatment is troublesome for youngsters
Solution Approach 1:
The visual field is segmented into different regions with different image content characteristics. The fellow eye receives images with certain spatial frequency content while the amblyopic eye receives images with different content, allowing both eyes to function simultaneously without suppression.
Solution Approach 2:
Different quality characteristics are applied locally to different eyes through the display system. The fellow eye receives high-quality images while the amblyopic eye receives images with specific modifications, creating localized treatment effects without requiring occlusion.
2Reliability
If standard patching regimens are used, then amblyopic eye stimulation is increased, but the fellow eye cannot contribute normally to binocular vision
Solution Approach 1:
The treatment merges binocular stimulation with monocular enhancement. Both eyes receive visual stimulation simultaneously, but the amblyopic eye receives enhanced stimulation through the dichoptic display, allowing both monocular and binocular functions to coexist and improve together.
Solution Approach 2:
The system dynamically adjusts image parameters such as spatial frequency, contrast, and temporal characteristics based on real-time feedback about binocular function. This dynamic adaptation allows the system to optimize treatment effectiveness while maintaining binocular vision capabilities.
3Measurement precision
If routine evaluation visits to eye care specialists are required, then treatment efficacy can be monitored, but treatment time and cost increase
Solution Approach 1:
The system performs self-monitoring of treatment progress through integrated sensors and algorithms that continuously assess binocular function during normal use. This eliminates the need for frequent manual evaluations by eye care specialists while maintaining accurate monitoring of treatment efficacy.
Solution Approach 2:
The system incorporates continuous feedback loops that monitor binocular vision parameters in real-time and automatically adjust treatment parameters. This closed-loop control enables precise monitoring of treatment progress without requiring external evaluation visits.

AI summary
This invention is a game platform for the assessment and/or treatment of disorders of binocular vision, such as amblyopia. The game content is devised to maximize the possible therapeutic effects by leveraging advanced research in ophthalmology, as well as advanced display technology to render images independently to each eye. In particular, the game content engages both eyes at different levels of difficulty, forcing an amblyopic eye to work harder to regain its performance in the visual system. The invention herein described provides a mobile device, capable of interaction with an eye care specialist, for the assessment/treatment of binocular vision using innovative mechanisms for ensuring proper use thereof.
