A pilot study of 21 patients found that sequential unassisted, home-administered virtual reality visual field (VRVF) tests were reliable and accurate as well as easy to use and comfortable. Reporting in the Journal of Glaucoma, the authors said the study is novel “compared with other reports on remote VF testing because of its longevity, study sample, and comparison to the standard testing paradigm.”

Patients had a baseline standard automated perimetry (SAP) test and then tested remotely on a VRVF device for 4 weeks, the last 3 unassisted. Researchers compared the mean sensitivities of VRVF results with each other and to SAP results for reliability. 

External factors may impact at-home testing, and age and visual impairment may hinder fixation, wrote Danielle E. McLaughlin, MD, and colleagues from the Bascom Palmer Eye Institute, University of Miami Miller School of Medicine. They recommended future studies.
