Given that many patients have mobility issues, office space is at a premium, staff can be stretched thin, and it’s Optometric Management’s clinical technology issue, ODs may want to investigate using virtual reality headsets. Worn by the patient, the portable devices can perform various tests. The following are available:

• Heru Platform (Heru, Inc.): This is a multi-modal augmented/virtual reality headset that allows physicians to perform six vision diagnostic exams to detect progressive, sight-threatening eye conditions, such as glaucoma, cataracts, and AMD. The platform performs: VFs (suprathreshold and full threshold), contrast sensitivity, color vision (Ishihara and Farnsworth D-15), and dark adaptation. 
  

  

  
  Additionally, the Heru platform tracks the patient’s eye movement using ActiveTrack to ensure the pa- tient’s fixation is always appropriate, resulting in fewer fixation losses. Heru’s Autoflow adapts and predicts an optimized full-threshold testing workflow in a short testing time, ensuring continuity of care with clinical results strongly correlated to legacy perimeters (seeheru.com ).
• SmartSystem VR headset (M&S Technologies): This virtual reality vision testing system allows for testing in a fully illuminated room and requires no internet connection to operate. The headset, with built-in eye tracking for fixation monitoring, provides accurate 10-2, 24-2, and 30-2 VF and contour stereo testing, M&S technologies says. The headset is adaptable to add many SmartSystem vision testing modules (mstech-eyes.com ).
  

  

• VisuALL VR devices (Olleyes): This virtual reality headset is available in three different products (Visual ETS, Visual S, Visual H) that offers perimetry, VA, color vision, contrast sensitivity, and low contrast VA testing, an automated comprehensive eye examination suite, and extraocular motility, pupillometry, and VF with eye-tracking testing. The latter model has been proven to allow for the home monitoring of patients in recent studies. (https://olleyes.com ).
  

  

• XO Exam System (Xenon Ophthalmics): This is a headset that contains VF testing featuring liquid lens technology that decreases errors and delivers one’s refractive correction in seconds, Xenon Ophthalmics says. Additionally, its eye-tracking software improves both the accuracy and reliability of test results, and eye care providers can continuously monitor eye position via the headset’s built-in camera, which shows a live video feed, the company says. The device also offers aberrometer and phoropter modules, set to release in 2023. Commercial availability of the system is expected by the end of 2022, according to a company press release.
