Figure 2. Mean number of peaks in Western blots against optic nerve antigens

Mean number of peaks in sera of subjects with primary open-angle glaucoma (POAG), normal tension glaucoma (NTG), ocular hypertension (OHT), and healthy volunteers (CTRL). Against optic nerve antigens, no significant difference in the number of peaks can be found in POAG, OHT, or NTG compared to controls.
