Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring a field of vision require patient cooperation and specialized equipment, limiting accessibility and reliability of the measurements.
Innovation Solution
An implant with a transponder coil for intraocular pressure measurement is used to objectively measure eye movement parameters, allowing for continuous, independent monitoring of the field of vision using a reading coil and storage means, enabling data transmission and evaluation without requiring complex optics or specialist presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If perimetry with optical stimuli is used to measure field of vision, then measurement precision can be achieved, but patient cooperation and presence of trained specialist are required
Solution Approach 1:
The system enables self-measurement by the patient using a mobile device to record eye movements and field of vision boundaries without requiring a trained specialist to perform the measurement, while maintaining measurement precision through automated tracking algorithms
2Reliability
If perimetry is performed in a doctor's practice with appropriate measuring systems, then reliable measurement can be obtained, but patient must visit clinic frequently
Solution Approach 1:
The patent replaces complex optical measuring systems with a mobile device equipped with a camera and accelerometer, enabling reliable field of vision measurements to be performed at home without requiring clinic visits or specialized equipment
3Measurement precision
If static perimetry with fixed location stimuli is used, then field of vision boundaries can be determined, but measurement is subjective and requires patient signaling
Solution Approach 1:
The system replaces subjective patient signaling with objective automated detection using a mobile device to track eye movements and determine field of vision boundaries based on recorded movement patterns, eliminating the need for patient cooperation during measurement

AI summary
To specify an arrangement and a method for measuring a field of vision of an eye (6) which, while avoiding the disadvantages of the prior art, enable an objective, less complex and more reliable measurement of a field of vision of an eye (6), it is proposed that the arrangement comprises measuring means (1, 3) for measuring an eye movement and in the method, the eye movement is measured in an initial measurement (S1). Furthermore, the use of an implant (2) comprising a transponder coil (1) for introduction into an eye (6) for determining an intraocular pressure for the objective measurement of the boundaries of a field of vision is proposed.
