Glaucoma and Alzheimer's disease: Their clinical similarity and future therapeutic strategies for glaucoma

Figure 1 Representative examples of normal, Alzheimer’s disease and Alzheimer’s disease-like cerebral perfusion patterns by SPECT images (sagittal sections and 3D images). A: Normal pattern; B: AD pattern; C: AD-like pattern. Arrows indicate decreased CBF; D: Comparison of relative CBF in the parietal lobe between NTG patients and controls. ^aP = 0.02, paired t-test; E: Classification of cerebral perfusion patterns by SPECT images in 64 patients with NTG. AD: Alzheimer’s disease; NTG: Normal tension glaucoma; CBF: Cerebral blood flow.
