Representative cases of SAP–FDT difference in peripheral nasal step (PNS) and parafoveal scotoma (PFS) in early stage of open-angle glaucoma. (A) A 51-year-old woman with PNS presented with great SAP–FDT difference. (A-1,A-2). Lamina cribrosa depth (LCD) of 727 μm and lamina cribrosa curvature index (LCCI) of 19.21 was larger (A-5) than those of eye with PFS (B-5). (B) A 50-year-old man with PFS presented with 14 abnormal points in FDT and 16 abnormal points in SAP (B-1,B-2). Fundus photography showed disc hemorrhage (yellow arrow) (B-3). Peripapillary choroidal VD of 53.80% was low (B-4).
