psi2oct: Angle of incidence in the OCT scan corresponding to angle of incidence in optic nerve head
Description
Obtains the angle of incidence in the circular oct scan from the average path that starts at an angle psi from the optic nerve head.
Usage
psi2oct( psi, diam = 12 )
Arguments
psi
Angle of incidence of the average bundle path on the optic nerve head
diam
Diameter of the scan. Default value is 12 in visual angle, which is the common diameter used in this types of OCT scans
Value
The angle of incidence in the circular oct scan
Details
The operation psi2oct( gloc2psi ) maps vf locations with RNFL angles so that the thickness that corresponds to each vf location can be estimated. This can be used in conjuction with vf2gcloc to correct for ganglion cell body displacement from vf location
