RVO = retinal vein occlusion, POAG = primary open-angle glaucoma, RNFL = retinal nerve fiber layer, GCIPL = ganglion cell-inner plexiform layer. * General linear model with analysis of covariance. † Age, sex, average RNFL thickness, and signal strength of optic disc scan adjusted mean ± SD. § Age, sex, average RNFL thickness, and signal strength of macular scan adjusted mean ± SD. ‡, ¶, # In patients with a ‘damaged hemisphere’ in the superior hemisphere, the thickness parameters of this hemisphere were converted upside down: superior interchanged with inferior, superotemporal with inferotemporal, and superonasal with inferonasal. As a result, the inferior hemisphere was the ‘damaged hemisphere’ in all patients.
