Visual Field Evaluation System for Glaucoma Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current eye examination methods for visual field evaluation, particularly for glaucoma detection, lack accuracy and user-friendliness, as they often require specialist supervision and do not facilitate early detection of visual field abnormalities.
Innovation Solution
An information processing system that includes a visual field evaluation screen with moving objects, allowing users to input manipulations to determine positional relationships and generate evaluation information, which can also provide training screens and alerts for distance and visual field assessment, using computer processors for accurate and accessible visual field evaluation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user performs visual field evaluation without specialist supervision, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The system enables users to perform visual field evaluation independently without specialist supervision. The automated guidance system provides step-by-step instructions, and the system automatically processes responses to generate evaluation results, allowing users to serve themselves while maintaining evaluation quality through structured protocols and automated analysis.
Solution Approach 2:
The system incorporates feedback mechanisms where the computer provides real-time guidance based on user responses. The system analyzes user inputs, compares them against expected patterns, and adjusts guidance accordingly to ensure accurate evaluation while maintaining ease of use for non-expert users.
2Measurement precision
If multiple objects are displayed in different regions, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The visual field evaluation is segmented into multiple regions (first region, second region, third region) with different objects displayed in each. This segmentation allows simultaneous assessment of different visual field zones, improving measurement precision by covering broader areas while the computer automates the complex coordination of multiple displays and responses.
Solution Approach 2:
The display system serves multiple functions by presenting different types of objects (first object, second object, third object) in different regions simultaneously. This multi-functionality enables comprehensive visual field assessment including central and peripheral vision evaluation, as well as detection of various abnormality patterns, all through a single integrated system.

AI summary
An information processing system includes circuitry configured to control display of a visual field evaluation screen including a first, a second and a third objects, the first object being displayed in a first region set in a central portion of a display screen, the second object moving in at least a part of the first region, and the third object being displayed in at least a part of a second region for a predetermined time, perform a first determination to determine whether a positional relationship between the first and the second objects satisfies a predetermined condition in response to a first manipulation input from a user, perform a second determination to determine a second manipulation input from the user while the third object is being displayed in the second region, and generate evaluation information for a visual field of the user based on the first and the second determination.
