Specvis: Free and open-source software for visual field examination

Fig 6

Intra-test variance for all visual field tests, subjects, and groups each using different fixation monitor technique, i.e. Blindspot, Fixation point change, and Both.

Each subject’s violin consists of six global variance values calculated across all six visual field graphical maps. Middle line present in each violin plot represents the median. Bottom and top “whiskers” of the plots are variance extrema. The smaller the spread between the extrema, the lower inter-test variance.
