Virtual reality technology for visual field testing involves using a separate iPad or screen that displays the patient's visual field in real-time. The screen shows where the patient is missing targets or not looking at them correctly. The virtual reality headset provides a 360-degree view of the visual field, which ensures that the test covers all areas of a patient's vision.
The visual field test generates a printout that highlights the specific areas where the patient has missed targets or has a defect in their visual field. These areas can indicate the presence of eye diseases, such as glaucoma, macular degeneration, diabetic retinopathy, and strokes. Different diseases can cause different types of visual field loss, such as central or peripheral field loss, and the location of the visual field loss can indicate the affected area of the brain.
