Assessment

Primary outcomes

To determine the proportion of cases that are inconsistent with those that follow the conventional order of abnormal appearance among the Humphrey visual field, Pulsar visual field, retinal ganglion cell thickness, peripapillary nerve fiber layer thickness, and macular and peripapillary retinal perfusion density and then to identify the factors associated with the discrepancy using a logistic multiple regression model.
