Retinal Vision Aid Redirecting Light to Functional Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for vision impairments such as age-related macular degeneration (AMD) and glaucoma do not effectively address the loss of central or peripheral vision, as there is no approved treatment for dry AMD and vision loss in glaucoma progresses gradually, affecting the ability to perceive a complete field-of-view.
Innovation Solution
A device comprising optical components like prisms, mirrors, and lenses, or cameras with a microprocessor and display screens, which redirect or manipulate images to project functional areas of the retina, allowing individuals with impaired vision to perceive a more complete field-of-view by distributing light or image information from non-functional areas onto functional areas, using retinal maps to customize image transformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If optical components or image processing devices are used to redirect light or image information onto functional areas of the retina, then the field-of-view coverage is improved, but the device complexity increases
Solution Approach 1:
The device segments the visual field into multiple regions corresponding to functional and non-functional retinal areas. Optical components divide the incoming light path into separate channels, each directed to appropriate retinal regions, thereby covering a broader field-of-view through systematic division of visual information processing
Solution Approach 2:
The patent introduces optical intermediaries (prisms, mirrors, lenses) and electronic intermediaries (cameras, display screens) that mediate between the external visual environment and the retina. These intermediaries capture, process, and redirect visual information to functional retinal areas, effectively expanding the usable field-of-view without directly modifying the retina
2Loss of information
If images are transformed and compressed to fit functional areas of the retina, then the information utilization efficiency is improved, but the processing complexity increases
Solution Approach 1:
The patent applies two-dimensional image compression and transformation algorithms that map visual information from a standard field-of-view onto the distorted geometry of functional retinal areas. This dimensional transformation efficiently packs more visual information into the available functional retinal space, maximizing information utilization while maintaining spatial relationships through computational mapping
Solution Approach 2:
The system dynamically adjusts image transformation parameters based on the specific pattern of retinal dysfunction. By changing compression ratios, mapping coordinates, and distortion correction parameters according to individual patient needs, the device optimizes information transfer efficiency while adapting to varying degrees of retinal damage
