In this video, we will cover the information that is included in re:Vive by Heru.
First, you will need to evaluate the reliability of the results by referring to the reliability indices. Heru testing monitors whether the patient is fixating using Heru ActiveTrack™ technology that always monitors the patient’s gaze. If the patient loses fixation, Heru will prompt the patient to look at the fixation target and “wobble” it to draw attention. For some patients, tracking the optic nerve head will work better. When the test switches to tracking the optic nerve head, you will see fixation losses appear real-time in the visual field report to assess reliability.
Second, the threshold value map provides a decibel value for each tested point. The higher the number, the more sensitive the patient’s vision is in that area.
Third, the grayscale map provides a visual representation of the decibel sensitivity seen on the threshold value map. The darker areas correlate to the lower values, indicating lesser sensitivity in those areas.
Fourth, the total deviation maps compares the decibel sensitivity and compares it to others in that specific age group, and highlights points that fall outside of the normal range.
Fifth, the pattern deviation maps shows more localized deviations. It corrects for generalized decreases.
Sixth, Mean Deviation (MD )is the weighted average of the total deviation values. As the patient’s visual field worsens, the MD value becomes more negative.
Seventh, the Pattern Standard Deviation (PSD) is an index for localized visual field loss. The PSD value is higher when there are irregularities in the field.
Eighth, the Probability Symbols show the statistical significance of each decibel group.
