Visual field mean deviation and threshold values found with Heru’s automated visual field testing platform strongly correlated with those of the Zeiss Humphrey Visual Field Analyzer, according to a study released during Vision Expo West.

Heru’s re:Vive is a portable mixed reality headset designed to provide automated screening and diagnostic exams without the constant presence of a physician, the company said in a press release.

The study, which included 47 eyes (21 healthy and 26 with glaucoma and neuro-ophthalmic diseases) found strong correlations between re:Vive and Humphrey Field Analyzer (HFA) visual field mean deviation and threshold values in all subjects. An additional study involving 34 subjects showed similar results, according to the release.

“Our patented re:Imagine threshold algorithm in the re:Vive platform shows a strong correlation with the Humphrey SITA Standard with excellent reproducibility and a shorter testing time,” Heru CEO and founder Mohamed Abou Shousha, MD, PhD, said in the release.

The study showed the re:Vive by Heru platform was 15% faster than the HFA SITA Standard in eyes with pathology and 8% faster in healthy eyes, the company said.

“Unlike legacy technology that requires patients to fixate on a static location for uncomfortable lengths of time, Heru’s patented ActiveTrack real-time gaze tracking confirms the patient’s fixation is always appropriate, improving data quality while keeping the patient engaged and focused throughout the exam,” Heru chief marketing officer John Trefethen said in the release.

The technology, which was created at the University of Miami’s Bascom Palmer Eye Institute, provides flexibility to collect data anywhere in the office or at a remote location, according to the release.
