fdplocmap: xy-position mapping between FDP device convention and...

Description Usage Format Author(s) References See Also


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.




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


stimulus x position


stimulus y position


sequential location number in the original device


size of the stimulus presentation


angle of incidence in blind spot from Jansonious map


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


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