[New visual field testing possibilities (a preliminary report)]

Area of Science:

• Ophthalmology
• Medical Technology
• Visual Science

Background:

• Current portable perimetry options are limited, restricting visual field testing to clinical settings.
• Visual field testing is crucial for diagnosing and monitoring conditions like glaucoma.

Purpose of the Study:

• To develop and evaluate a mobile perimetry technique utilizing a virtual reality (VR) headset.
• To assess the feasibility and accuracy of VR-based perimetry for visual field testing.

Main Methods:

• 26 patients (30 eyes) with primary open-angle glaucoma (POAG) underwent visual field testing.
• Testing was performed using a standard Humphrey analyzer and a VR headset integrated perimeter (Total Vision, Russia).
• Results were compared using a similar testing strategy (30-2, 76 points) with intervals of 1 hour to 3 days.

Main Results:

• The VR headset-based perimetry demonstrated a high degree of identity with the Humphrey analyzer results.
• Patients tolerated the VR examination well.
• The VR headset effectively eliminated distractions and ensured stable light conditions.

Conclusions:

• The developed VR headset-perimeter is a viable, portable, and mobile solution for visual field testing.
• This technology offers comparable accuracy to conventional methods and can be used by visiting medical teams or for home examinations.
• It enhances accessibility for individuals with glaucoma, allowing testing outside traditional clinical environments.
