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

Description

A table with relevant information about test location data for each pattern of locations, 24-2, 10-2, and 30-2, and the conventional Goldman size III stimulus. 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.

Usage

data( saplocmap )

Format

The structure saplocmap has 1 table for the test pattern p24d2. The 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
