Visual Field Test Machine: A Comprehensive Guide to Automated Perimetry for Glaucoma Screening

Do You Know?

According to a 2020 report, approximately 80 million people worldwide have glaucoma, with 60 million affected by open-angle glaucoma.

Vision loss can be caused by a range of factors, but the major one is glaucoma. 

In this condition, the optic nerve gets damaged by the pressure of blood.

As it damages the main nerve of the eyes that transmits the information to the brain, if this gets damaged, then the patient will suffer permanent vision loss.

To detect it at early stages, an eye test is mandatory. An innovation helps the ophthalmologists by supporting them in eye examinations. 

It is a VR headset that performs as a visual field test machine, providing more accurate images of the optic nerve and providing effective results. 

It provides the result of each change in the eye which are unnoticed by the professional during certain instances. 

In this article, we will discuss the Visual Field Test Machine, which helps in glaucoma screening effortlessly and accurately.

Understanding Automated Perimetry for Glaucoma

This method maps the field of vision of individuals by detecting how well they can see an object in their peripheral vision. 

It’s going to help identify if there’s damage in the patient’s optic nerve due to glaucoma, which can lead to vision loss. 

The results are plotted in such a way that it’s going to creates a visual representation of blind spots, and it’s later analyzed for further diagnosis.

Automated systems use algorithms to calibrate the responses of the ones being tested to the visual stimuli and measure their reactions. 

It’s a machine that’s designed to adjust to the challenges of each stimulus based on the responses that it’s receiving. 

The result is often consistent, and it reduces human error, so the specialists will be able to interpret the findings accurately. 

Over time, it can determine if the treatments for glaucoma are effective or if there’s progress at all.

Since the process is standardized and there’s no subjective variability, the automated perimetry is more objective. It’s going to be an essential part of a clinic that sees a lot of patients daily, and the practitioners can get data that can support long-term care plans. 

They can also reproduce the test on another testing machine and get the same results as automated perimetry because this provides high-level diagnostics.

A VR is a great alternative to bigger machines because it’s more flexible. Usually, the patients will look at a bowl-shaped perimeter, and the eye that’s not going to be tested will be covered. 

They will be asked to keep looking, and dim lights will begin to appear at various places throughout the bowl. 

A button should be pressed when the patient sees a light, and the machine is going to record what he didn’t see. See info about virtual reality when you go to this site here. 

Lightweight with the portability of the analyzers, it’s also going to be a good option for clinics in remote areas.

Features of Modern Testing Equipment

Most analyzers today are designed to optimize their functionality, and a compact device like a VR is often lightweight. 

It’s compact which aims to reduce the total physical strain that’s typically associated with old machines, and they can save space. 

They also offer flexibility, especially in how the test is administered, and they can be used in mobile clinics.

Some advanced models provide high-resolution displays, which makes them a good choice for quick tests. The eye-tracking technology has been clinically validated. 

It’s also compliant with the ADA as a model of accessibility, and it involves active eye tracking.

Customizable models are also available with upgraded internal optics and rich 4 K displays. 

Some of them can test for contrast sensitivity or visual acuity, and clinicians can schedule a demo today to see how the VR works. 

Many of the devices work by accommodating various patients, where some might have difficulties staying still due to health concerns.

This makes it difficult for the classical machines that are bigger. Modern machines are more inclusive, and it’s a great return on investment.

 Clinics will be able to see more patients, and the tests will be performed in less time, which enables the device to pay for itself.

Advantages for Patients and Eye Care Providers

Testing is easily done with the VR, and it’s faster than the traditional methods. 

People feel more comfortable when it comes to eye assessments, and it encourages them to turn to regular testing. It’s a great tool for eye disease management, and the shorter sessions will reduce fatigue. 

It can lead to accurate results, and patients who are often reluctant to undergo eye exams are going to be more compliant when the tests are less intrusive.

Eye care professionals will also have more consistent results even on a busy clinic day.

 With the automated interface, the staff can conduct the tests without undergoing the steep learning curve that many older systems require. 

Most of them will have more time to discuss the results with the patients, especially if there are signs of eye disorder and make sure that they develop the right treatment plans.

With the portability of the analyzers, it’s also going to be a good option for clinics in remote areas. 

There’s no need for the internet, and the elimination of bulky equipment can help bring eye healthcare services to underserved communities.
