OCTOPUS® Visual Fields showing severely constricted bilateral fields, with only central island of field preserved in both eyes. In this kinetic perimetry study with stimuli V4e and III4e (indicating the largest and brightest light stimuli settings), there is significant constriction of visual fields bilaterally. In this study, both bilateral vertical and horizontal field extends no further than 20 degrees from fixation in all 4 quadrants. This is stark comparison to normal visual fields which extends 90 degrees temporally to central fixation, 50 degrees superiorly and nasally, and 60 degrees inferiorly (indicated by shaded outline)
