Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity in using existing fundus imaging apparatus and perimeter devices for eye examinations leads to unnecessary procedures and increased time due to differences in optical systems and examination methods, making it challenging for examiners unfamiliar with these devices to perform effective examinations.
Innovation Solution
A control method that integrates a fundus imaging apparatus with a perimeter, allowing for cooperative use by processing examination data to obtain positional information of abnormal sites and setting examination positions, enabling controlled imaging and analysis of the fundus using both devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fundus imaging apparatus and perimeter are used separately with different examination methods, then each device can perform its specific function, but the examination process becomes complex and time-consuming
Solution Approach 1:
The patent combines fundus imaging apparatus and perimeter into a single integrated system that shares common hardware resources (light source, optical system, detector) while performing both visual field measurement and fundus imaging functions. The control unit coordinates both examination types through a unified interface, eliminating the need for separate device operations and reducing examination time.
Solution Approach 2:
The integrated system is designed to perform multiple functions using the same hardware platform. The optical system can switch between presenting visual field stimuli and capturing fundus images, while the detector processes both types of optical signals. This multi-functionality reduces device complexity and improves ease of use despite the diverse examination requirements.
2Reliability
If examiners are unfamiliar with the differences between fundus imaging apparatus and perimeter, then each device maintains its specialized functionality, but unnecessary examinations are performed and diagnostic efficiency decreases
Solution Approach 1:
The integrated system incorporates a control unit that automatically processes examination data from both the perimeter and fundus imaging components. The system provides feedback by analyzing the results and generating coordinated examination plans, reducing reliance on examiner expertise to interpret the differences between examination types and improving diagnostic efficiency.
Solution Approach 2:
The system performs automatic data processing and analysis functions that were previously requiring examiner intervention. The control unit autonomously coordinates the examination sequence, processes the combined data from both examination types, and generates diagnostic information, thereby improving productivity while maintaining reliability.
3Measurement precision
If separate examination procedures are used for fundus imaging and perimeter, then each examination can be optimized for its specific purpose, but the overall examination process becomes complicated
Solution Approach 1:
The patent merges the optical systems of fundus imaging and perimeter into a single integrated platform, reducing device complexity while maintaining the precision of both examination types. The shared optical components and unified control architecture simplify the overall system while preserving the specialized measurement capabilities of each examination mode.

AI summary
A control method of a fundus examination apparatus constructed as a perimeter for examining a fundus of an examinee's eye, includes: controlling a monitor provided in the fundus examination apparatus as the perimeter to display a two-dimensional map pertinent to a two-dimensional analysis result of the fundus based on a tomographic image of the examinee's eye obtained by an optical coherence tomography device; setting an examination position in the fundus examination apparatus as the perimeter on the two-dimensional map displayed on the monitor; and controlling the fundus examination apparatus as the perimeter based on the set examination position to examine the fundus.
