GarwayHeath R Documentation
Garway-Heath angles for the HFA-II
Description
These Garway-Heath angles are used as the dissimilarity metric when implementing the boundary
detection model for a longitudinal series of visual fields.
Usage
data(GarwayHeath)
Format
A vector with length 54, where each entry represents the angle (in degrees) that the
underlying retinal nerve fiber enters the optic nerve head. The measure ranges from 0-360,
where 0 is designated at the 9-o’clock position (right eye) and angles are counted counter
clockwise. These angles are estimates for the Humphrey Field Analyzer-II (Carl Zeiss Meditec
Inc., Dublin, CA). The 26th and 35th entries are missing as they correspond to a natural
blind spot.
