Figure A5.

Convergence angles (or corresponding fixation distances) and scotoma widths at which the ONH scotoma intersects the contralateral CFL scotoma. Lines for the close, far, temporal, and nasal intersection points are shown. An intersection exists at a finite distance for all points above its corresponding line. ONHs are assumed to be centered 15° temporal of fixation, with a width of 5° and an IPD of 6.6cm. The close and temporal limit lines go negative at the point that the ipsilateral CFL scotoma begins to and then fully overlaps the ONH scotoma, making the ONH interaction moot.
