GC-IPL = ganglion cell-inner plexiform layer; MRI = magnetic resonance imaging; RNFL = retinal nerve fiber layer.
All values for the total population are given as means (standard deviations) or as frequencies.
Cerebrovascular lesions were defined as brain infarction or hemorrhage on MRI regardless of the presence of absence of neurological symptoms.
