Virtual reality has turned what was science fiction into reality. Visual field testing and other visual acuity tests can be performed using a head-mounted VR perimeter. All of this is done with little to no human supervision and with promising results.
Experts say VR visual fields can be beneficial for screening as an additional tool in the clinic. Its applications could also extend to the world of telemedicine. nevertheless, VR visual field test Technology has a long way to go. This article explains what you need before using it in place of regular automatic perimetry. Therefore, in this article, we will reveal what you need to know about this technology.
virtual reality highlights
There is much to look forward to in this new world of computer-generated care. This includes faster thresholding, reduced capacity, and improved usability. Glaucoma experts say the following about glaucoma:
eye tracking technology
One of the key parts of many VR viewing devices is technology that precisely tracks eye movements. This technology can also modify the test to suit the user. The patient is asked to look at a central target, and the device moves across the visual field. This exposes the specific part of the retina that should receive the light.
Micro Medical Devices’ VF2000 is an example of a VR device with this capability. The machine alerts the patient when the patient’s eyes move off center. You can then refocus on the center mark. This is something you can’t do on a regular machine.
A standard perimeter requires at least one technician to be in the room. This individual is always aware of the loss of fixation and informs the patient about it. This leads to overall efficiency.
Reflection-friendly fovea
Similarly, some VR boundaries do not require focusing on a central point at all. For example, the Vivid Vision Perimeter (Vivid Vision) uses a test method that asks the patient to move their head. In some cases, you may be asked to move the pointer toward a fixation, stimulus, or gaze task. After this, they are asked to perform a stimulus task.
Each time a stimulus is displayed, the patient is looking at the stimulus rather than focusing on the central target. This makes it easier for patients to understand and perform the test. This is because you don’t have to fight the urge to look at the stimulus.
patient comfort
The VR perimeter provides a more comfortable environment for the patient compared to standard automatic perimeters. For example, VisuALL (Olleyes) allows patients to sit in any position. These headsets also allow you to take the test from your wheelchair, exam chair, or waiting room chair.
Glaucoma patients often have other health problems, such as back and neck pain. can read This article To learn how to live better with glaucoma. Therefore, it may be difficult to sit on a standard machine. Additionally, it can be difficult to position the patient correctly.
This is because your face must be touching the bar and your chin must be within your chin cup. Therefore, tilting the head may result in different results compared to the normal position. Virtual perimetry can be very helpful for such patients. These devices have been used for people who do not get good results with regular machines.
These gadgets are also great for testing on children. It’s hard to patch kids, but you don’t need to patch these devices. They don’t know which eye they’re looking through. As you can see, it’s very simple.
Testing for advanced glaucoma
VR testing is also useful for patients with advanced glaucoma who have a small island in the center of their vision. With the standard model, it is difficult to see the eye line and position. These devices make it easier to find the central fixation point because it is closer to the eye and position is less important.
easy to use
Many VR perimeters include audio and video capabilities to teach patients how to take the test. They tell the patient how well the test is going. These features make your testing environment more comfortable.
Tests and explanations are easy to understand. Patients prefer Humphrey vision because it is more comfortable and less tiring than Humphrey vision. It is easy to use and requires no training or classification.
save time
Physicians save time by not having to move patients around the clinic when checking visual fields virtually. can visit Learn more about how to prepare for your visual field test. In-headset training also reduces the need for expert testing. This will save you that time.
affordable price
VR Perimeter isn’t very expensive, but prices vary. Something has to be done to allow patients to take these at home. Experts suggest that it is necessary to design the software, not the device itself.
home test
Similarly, experts say that in-home testing could be an application for VR perimetry in the future. It would be fun if patients could test themselves. That way, your doctor can see your results from anywhere.
remote screening
Because these devices are portable, they can be used in locations where regular visual field testing is not available. These headsets become even more useful for screening as new features are added. You can also make sure that many of them are clearly visible.
They can tell the difference between the colors and see how their students are reacting. Some people are doing research to check eye motility. Adding fundus images is also a great feature.
conclusion
VR visual field testing has many advantages, including patient comfort, ease of use, and remote testing. This technology has some advantages, but is still under development. There are still some issues that need to be solved to fully replace traditional boundary measurement methods. But the improvements point to a bright future for both hospitals and homes.
