Figure 7.

Superimposition of kinetic perimetry isopters (from a single representative healthy subject) found using Goldmann size I and size II (equivalent to the HFA 24 dB [log Weber contrast 0.103] level of stimulus intensity) and a two-way Method of Limits (peripheral to central “inner” isopter and central to peripheral “outer” isopter) as per Phu et al.³ on the 30-2 spatial map. The colored test locations in the 30-2 test grid reflect age-specific CSIs found in Figure 5, and show approximate concordance with the isocontrast area bounded by the inner and outer kinetic isopters.
