Amblyopia Correction via Dynamic Visual Content Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for amblyopia and ocular deviation, such as occlusion therapy and atropine, face compliance issues and instability in visual gains, while traditional therapies for ocular deviation are uncomfortable and can cause eye strain, highlighting the need for effective non-invasive methods to diagnose and correct visual disorders.
Innovation Solution
A system and method that involves measuring visual functions of both eyes, modifying visual content using image processing to enhance or reduce specific parameters, and adjusting display positions to align images correctly, allowing for amblyopia and ocular deviation diagnosis and correction through a head-mountable display system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If occlusion therapy is used to treat amblyopia, then visual acuity improves, but patient compliance deteriorates due to personal distaste, skin irritation, and cosmetic embarrassment
Solution Approach 1:
The patent replaces the mechanical occlusion therapy (eye patching) with a visual processing system that uses image enhancement and selective presentation to the amblyopic eye. The system processes visual content through a camera and display device, applying computational algorithms to enhance images for the weaker eye without requiring physical occlusion, thereby maintaining visual acuity improvement while eliminating compliance issues related to skin irritation and cosmetic concerns
Solution Approach 2:
The system changes the parameters of visual content presentation by dynamically adjusting image enhancement levels, contrast, brightness, and spatial frequency based on the amblyopic eye's visual function measurements. This allows the treatment to adapt to the patient's specific visual deficits and progress, improving visual acuity through customized visual stimulation rather than uniform occlusion
2Ease of operation
If atropine drug therapy is used to treat amblyopia, then patient compliance improves, but treatment speed deteriorates and optical function is paralyzed
Solution Approach 1:
The patent substitutes pharmacological atropine therapy with a visual processing system that uses computational image enhancement and selective visual presentation. This replacement eliminates drug-induced optical paralysis while maintaining treatment compliance, as the system delivers customized visual content through a camera and display without affecting the eye's natural optical functions
Solution Approach 2:
The system enables continuous visual stimulation and treatment through everyday activities by integrating the camera-display interface into daily visual tasks. Unlike atropine which requires extended periods of optical paralysis, the visual processing system can operate continuously during normal viewing activities, accelerating treatment speed while maintaining compliance
3Reliability
If traditional prism therapy is used for ocular deviation, then binocular vision improves, but eye strain increases when prismatic lenses are improperly adjusted
Solution Approach 1:
The system dynamically adjusts the parameters of visual content presentation, including image position, orientation, and enhancement levels, based on real-time measurement of the user's visual functions and ocular alignment. This adaptive parameter adjustment optimizes binocular vision fusion while minimizing eye strain, eliminating the need for static prismatic lenses that may be improperly adjusted
Solution Approach 2:
The system incorporates feedback mechanisms that continuously measure the user's visual response and ocular alignment, then adjust the visual content parameters accordingly. This closed-loop control ensures optimal binocular fusion is maintained while preventing eye strain, as the system adapts to the user's changing visual state rather than relying on fixed prismatic corrections
4Measurement precision
If occlusion therapy is used to treat amblyopia, then visual acuity improves, but visual gains regress when therapy ceases
Solution Approach 1:
The system provides continuous visual stimulation and reinforcement through integrated camera-display processing during everyday activities, rather than intermittent occlusion therapy. This continuous engagement of the visual system promotes stable neural plasticity changes, reducing regression when treatment ceases by maintaining consistent visual pathway activation
Solution Approach 2:
The system performs preliminary measurement and customization of visual content parameters before treatment begins, and continues to adjust parameters throughout therapy based on progress tracking. This preliminary and ongoing customization ensures optimal visual stimulation is delivered from the start, promoting more stable and sustained visual acuity gains
