xy-position mapping between FDP device convention and visualFields convention for patterns of location

Share:

Description

A table with relevant information about test location data for the pattern of locations 24-2. The convention for visualFields is to use always a right-eye format. That is, a left eye would be "flipped" left-right and location number are counted row-wise from top-left to bottom-right. Information about the size of the stimulus and the corresponding angle of incidence and slope with Jansonious map [1] are included.

Format

The structure fdplocmap has 3 tables, one for each test pattern: p24d2, p10d2, p30d2. Each table has six columns:

xod

stimulus x position

yod

stimulus y position

loc

sequential location number in the original device

size

size of the stimulus presentation

jmangle

angle of incidence in blind spot from Jansonious map

jmslope

orientation of an average bundle at that position of the visual field as calculated from the Jansonious map

region

region of the visual fields in comparison with ONH sector. Garway-Heath map
