Virtual reality perimetry

virtual reality perimetry

Virtual reality perimetry is a way of checking the full field of vision using a headset similar to consumer virtual reality glasses. Instead of placing your face at a large machine, you wear the headset while small lights or shapes appear in different places and you indicate when you see them. The test maps the areas where you can and cannot see, helping to identify blind spots and tiny changes in vision that may not be obvious in everyday life. It works by presenting visual targets at different positions and brightness levels and recording your responses and head movements. Because it uses a compact headset and software, this approach can be done in many settings and may even be offered for remote or home use with clinician oversight. It is often more comfortable and less intimidating than traditional devices, which can help children, older adults, and people with mobility issues complete the test. Software can also speed testing by adapting to your responses and focusing on areas of concern. However, the method still needs careful calibration and clinical validation to ensure results match standard tests, and some users may experience discomfort or motion sensitivity. Overall, it matters because it offers a modern, accessible tool to monitor vision, detect problems earlier, and help clinicians tailor care more quickly.
