MD – mean deviation; PSD – pattern standard deviation; VFI – visual field index; SAPrgc – Number of retinal ganglion cells estimated from SAP sensitivity values; OCTrgc – number of retinal ganglion cells estimated from optical coherence tomography data; wrgc – weighted estimated of the number of retinal ganglion cells; CSFI – combined index of structure and function.
