Summary of Proposed Objective Criteria for Definition of GON

	SDOCT	SAP
GON
Global loss	Global RNFL thickness outside normal limits	GHT outside normal limits or PSD, P < 5%
Localized loss	RNFL thickness outside normal limits in at least one superior sector (temporal superior and/or nasal superior)	Inferior MD, P < 5%
	RNFL thickness outside normal limits in at least one inferior sector (temporal inferior and/or nasal inferior)	Superior MD, P < 5%
Normal	RNFL thickness within normal limits for all sectors and global	PSD probability not significant (P > 5%) and GHT within normal limits

To be considered glaucomatous optic neuropathy, it was necessary to meet the criteria for global or localized loss. To be considered normal, it was required that both SDOCT and SAP results were normal. SDOCT-SAP pairs that do not meet the criteria for GON or normal are considered suspects. GHT, glaucoma hemifield test; PSD, pattern standard deviation; GON, glaucomatous optic neuropathy; SDOCT, spectral-domain optical coherence tomography; SAP, standard automated perimetry.
