Angle-Selective Eye Evaluation for Amblyopia Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vision screening methods for children and adults are inefficient, require trained personnel, lack standardization, and are not suitable for mass screening, especially for infants and individuals with unstable eye movements or developmental disabilities, and existing technologies like photoscreening and full examinations are costly and inaccurate.
Innovation Solution
A vision diagnostic and treatment system using a gaming platform that allows for vision assessment and treatment without glasses or goggles, utilizing a dynamic video game to test visual acuity, stereo acuity, color vision, and preferential looking, with automated data collection and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional manual vision screening methods are used, then trained personnel can assess visual acuity, but the process requires expensive technical testing machines and trained personnel which creates logistical barriers for mass screening
Solution Approach 1:
The patent replaces complex technical testing machines with a simplified digital display device (such as a smartphone or tablet) that presents visual acuity test content. The system copies the essential function of traditional testing machines by displaying optotypes or visual stimuli through a screen, eliminating the need for expensive specialized equipment while maintaining assessment capability.
Solution Approach 2:
The system enables self-administered vision screening where individuals can test their own visual acuity without requiring trained personnel to operate complex equipment. The automated presentation of test content and automated assessment of responses allows users to perform screening independently, removing the dependency on trained operators and expensive machinery.
2Measurement precision
If conventional testing methods with binary selection cards are used for infants, then visual acuity can be estimated, but the method requires expert screeners and has difficulty keeping infants interested or awake
Solution Approach 1:
The patent transforms the static binary selection card method into a dynamic digital presentation system. Visual stimuli are displayed on a screen with potential animation, color variations, and interactive elements that can adapt to infant behavior. This dynamic approach captures infant attention more effectively than static cards while maintaining the ability to assess visual acuity through preferential looking or fixation patterns.
Solution Approach 2:
The system utilizes color variations and changes in visual stimuli displayed on the screen to engage infants and maintain their attention during testing. By presenting colorful, changing visual content rather than monochromatic static cards, the system makes the testing process more appealing to infants, improving completion rates while preserving measurement accuracy.
3Adaptability or versatility
If photoscreening is used to evaluate vision in children, then very young or developmentally impaired children can be tested, but the method only checks for certain eye conditions and cannot assess visual acuity
Solution Approach 1:
The patent creates a multi-functional digital testing system that can assess multiple visual parameters including visual acuity, color vision, and stereopsis through a single platform. Unlike photoscreening which is limited to detecting specific eye conditions, this system presents various types of visual stimuli and measures multiple aspects of visual function, making it universally applicable for comprehensive vision assessment across different age groups and developmental levels.
4Reliability
If full professional eye examinations are performed in eye doctor's offices, then thorough screening for eye problems can be conducted, but the costs would be overwhelming and not all eye doctors are trained the same
Solution Approach 1:
The patent segments the comprehensive eye examination process into a standardized digital protocol that can be administered outside the doctor's office. By breaking down the examination into discrete, standardized test components delivered through a digital platform, the system maintains thoroughness while reducing dependency on individual examiner expertise and expensive equipment, enabling broader access to reliable vision screening.
Data Source
AI summary
A system for providing visual stimulation to a test subject having an amblyopic eye and a sound eye includes a screen and a controller. The screen configured to display image data, wherein each image data includes a first image data component viewable from a first angle and a second image data component viewable from a second angle, wherein the first image data component has an image quality that is higher than an image quality of the second image data component. The controller is configured to display the image data on the screen such that, when the test subject holds the screen, the first image data component is only viewable by the amblyopic eye of the test subject while the second image data component is only viewable by the sound eye of the test subject.
