Abstract

|
|
Purpose : The aim of this study is to propose an eye movement test that can be used in clinical practice through several improvements in the existing eye movement tests.
Methods : Based on the NSUCO test, the shortcomings of the test were improved by applying simple hardware and software. For hardware, it is a laptop, monitor, webcap and transparent grid paper, and as software, a target using MS office, Bandicam® for recording the observation process, and WinSplit Revolution 9.02® for dividing the monitor screen observed by a tester.
For the objectivity and reliability of the improved eye movement test, one tester retested the stored eye movement result images after 2 weeks for the repeatability and reliability of the test with 12 normal adults. Reliability between two testers who compared the results of image evaluation was confirmed.
Results : Test-retest and inter-test reliability were compared as an improved test using hardware and software added to the existing NSUCO test. Both tests did not show a significant difference (p<0.050), and the reliability comparison with the NSUCO test showed high reliability.
Conclusion : The improved eye movement test has been confirmed as a test that can be used in clinical practice by increasing the reliability between test-retest and tester by objectifying the existing NSUCO test environment.
