Eye Diagnostics TRIZ Cases
- VR Eye-Tracking Assessment for Visual Reaction Time Testing
A VR headset with eye tracking adapts optotype tasks in real time to measure visual processing speed, reaction time, and eye movement abnormalities.
- Gaze-Contingent VR Eye Tracking for Adaptive Ocular Assessment
Adaptive gaze-contingent VR testing uses self-calibration and real-time stimulus changes to assess eye-tracking stability and ocular disorders.
- VR Eye-Tracking for REM Sleep and Ocular Condition Detection
Eye-tracking in a VR headset monitors REM sleep, gaze, and pupil response to detect ocular conditions non-invasively at home or in clinic.
- HMD Pupillary Response Testing Under Controlled Light Exposure
An HMD alternates eye stimulation and captures pupil images under standardized lighting to improve RAPD detection reliability.
- Line-Field OCT Retinal Imaging Without Mechanical Beam Scanning
A fixed OCT scanline and stepped fixation target capture multi-position retinal B-scans, cutting OCT cost and complexity for home monitoring.
- Polygon Scan Line Alignment for Stable Ophthalmic Imaging
A fixed detector tracks each polygon mirror facet to synchronize scan-line starts and reduce ophthalmic image jitter from optical tolerances.
- Ophthalmic Pupil Alignment for Ultra-Widefield Fundus Imaging
Dynamic pupil-distance guidance adapts to pupil size, enabling automatic ultra-widefield fundus capture with less clipping.
- Stereo Pupil Alignment in Ultra-Widefield Fundus Imaging
Stereo pupil images taken through a fixed mirror orientation guide eye alignment while avoiding added optics, reflections, and artifacts.
- Ophthalmic Imaging Modality Switching With Shuttered Power Control
A shutter blocks the beam during modality changes while the controller adjusts source power, protecting the eye without sacrificing image quality.
- Head-Worn Eye Tracking Optics Without Fixation Points
A translucent, edgeless viewing chamber admits ambient light while removing fixation points for more accurate torsional eye tracking.
- Intraocular Illumination Calibration for Transscleral Color Control
Sensor feedback compensates for scleral color filtering during vitreoretinal surgery to keep intraocular illumination consistent.
- Functional Visual Field Analysis Across Postures and Tasks
Measures visual fields across changing postures and tasks to build a functional visual space for tailored lenses and treatment.
- Multi-Detector Tear Film Assessment Using Aligned Ocular Surface Data
Aligned OCT, aberrometry, and topography data reveal tear film abnormalities without invasive eye-surface procedures.
- Tear Film Imaging Optics for Automatic Eye Alignment
A shared optical path captures tear film fringes and wider anterior-eye images to detect X-Y-Z deviation without enlarging the instrument.
- Dry Eye Neurosensory Testing for Treatment Efficacy Assessment
A calibrated ocular provocation test battery measures neurosensory abnormalities in dry eye and tracks treatment response more accurately.
- Dual-Display Visual Function Measurement for Objective Accommodation Testing
Dual displays, motion sensing, and pupil tracking make visual function testing more objective and reproducible across different viewing distances.
- Foveal Photobleaching Endpoint Target for Cone Recovery Measurement
Focal white or color light bleaching uses a contrast endpoint target and gaze anchor to measure cone dark adaptation more consistently.
- Ophthalmic Image Partitioning for Full-Scale Multi-View Comparison
Partitioned synthesis of eye images enables side-by-side comparison without shrinking scale, preserving fine detail for more accurate examination.
- Ophthalmic Image Capture for Persistent Astigmatism Axis Registration
Interactive smartphone-guided eye imaging replaces fading ink marks with stored astigmatism axis references for surgical registration.
- Adaptive Visual Acuity Modeling for Cross-Chart Precision
Adaptive psychometric scoring standardizes visual acuity testing across chart types, improving precision and tracking changes over time.
- Adaptive Audio Guidance for Virtual Vision Testing Accuracy
Real-time sensor feedback adapts audio instructions and visual stimuli to improve virtual vision test accuracy on household devices.
- Gaze Tracking for Routine Neurological Weakness Detection
Eye movement tracking during normal visual tasks enables fast neurological weakness screening without lengthy specialist eye exams.
- Inflatable Eye Exam Mask With Anti-Reflective Sealed Ocular Cavities
An inflatable eye exam mask seals around the eye sockets and uses anti-reflective transparent sections to reduce cross-contamination and stabilize positioning.
