Scotoma mapping

REV. B 02/03 PN 51680-1
The Scotoma Mapping feature allows the user to measure the size of a scotoma through the
testing of multiple kinetic meridians. A point within the scotoma is located. When activated, the
Scotoma Map feature sends the stimulus outward from the central point (a fixed number of
times) to outline the boundaries of the scotoma.
