Summary
This study introduces an automated fundus perimeter system to simplify visual field testing. The computer-driven technology reduces manual effort and examination time for fundus perimetry.
Area of Science:
- Ophthalmology
- Medical Technology
- Computer Science
Background:
- Fundus perimetry is essential for diagnosing visual field defects but is often time-consuming and labor-intensive.
- Manual operations and involuntary eye movements complicate traditional fundus perimetry procedures.
Purpose of the Study:
- To develop an automated fundus perimeter system using computer technology to overcome the limitations of manual methods.
- To enhance the efficiency and precision of fundus perimetry through automation.
Main Methods:
- The system integrates an infrared fundus camera with computer-controlled pursuit and target-display units.
- Real-time tracking of the fundus reference region by the pursuit unit allows for precise stimulus targeting.
- The target-display unit automatically corrects stimulus coordinates based on real-time eye movement data.
Main Results:
- The automated measuring system enables precise and automatic execution of fundus perimetry.
- Examination duration is significantly reduced, freeing operators from laborious manual tasks.
- The system accurately displays stimuli on preset retinal points despite eye movements.
Conclusions:
- The automated fundus perimeter system simplifies the process for operators.
- This technological advancement is expected to increase the clinical adoption and popularity of fundus perimetry.
