Following our recent post about VRFocus’ recent trip to Korea in which we stopped in at MS2 to see their new virtual reality (VR) eye-testing solution, you can now see the test carried out in full in our latest video. VRFocus’ Editor Kevin Joyce took to the stage to have his eyes’ tested by the new system which could help to identify weakness or problems with a patient’s eyes by means of a few simple tests.
The eye test process starts with a short calibration which requires the patients to focus their eyes on a number of colour dots before the real test can begin. This is an important step as it helps to ensure the result that patients get at the end is a valid one. Once set up, the first test can be carried out and it is to see how off-center the patients eyes are. In order to test this they are required to look at and focus on some yellow dots for around twenty to thirty seconds. For this test Joyce scored a perfect result in this test which is a superb result.
Test number two checks the muscles around the eyes to ensure they are working properly. The yellow dot will once again need to be focused on as it slowly moves around the screen. As the set up is able to see the patients eyes and track their movements in relation to that of the yellow dot, a result can be drawn up on how effective the muscles around the eyes are working. The outcome is a graph that displays the patients movements against the path of the yellow dot which easily displays the data in a way that both doctor and patient can understand easily.
The third test is one to check a patients depth-perception. By using the computer mouse as a point the patient is asked to looked at a number of different blocks displayed in front of them and to select which one is always the closest to them. This is a tricky test, as seen in the below video, but one that is very important. The fourth test known as the Lancaster Test, which requires the patient to align a light with another one that is being displayed by the doctor. Due to wearing a red-green glasses or display, the patient sees each light with a different eye making it a challenging test. The measurement here is to see how well the patient can align each of the lights together.
Next, the patient needs to focus on dots and click the mouse when they see a white dot come into focus. The test is carried out with one eye at a time and from this test a weakness in the eyes can be detected. The test runs for ten minutes per eye normally but in the essence of time, Joyce did three minutes on each eye. From the outcome of the tests it was suggested that there may be some evidences of glaucoma to which it is suggested further testing be carried out.
