Comparison of the cupping depth of the optic disc among the iNPH+/NTG-, iNPH+/NTG+, and iNPH−/NTG+ groups. The cupping depth of the optic disc was measured using SD-OCT for patients in the iNPH+/NTG-, iNPH+/NTG+, iNPH−/NTG+ groups; the cupping depth for the iNPH−/NTG+ group was significantly greater than that for the other groups (p < 0.001). ***P < 0.001.
