Suh MH, et al. - The visual field (VF) sensitivity was compared according to the presence of parapapillary deep-layer microvasculature dropout (MvD_P) and focal lamina cribrosa (LC) defect. Findings suggested a difference in both retinal nerve fiber layer (RNFL) thickness and VF sensitivity among the 4 groups [eyes without either focal LC defect or MvD_P (group 1); eyes with focal LC defect but no MvD_P (group 2); eyes without focal LC defect but with MvD_P (group 3); eyes with both focal LC defect and MvD_P (group 4)] in all areas except the nasal and superonasal sectors for RNFL thickness. Compared to the eyes without MvD_P, those with MvD_P had worse VF sensitivity and VF difference was more distinguished than differences of axonal loss and focal LC change.
