Performance of the Visual Field Index in Glaucoma Patients With Moderately Advanced Visual Field Loss – Corrected Proof

Purpose: To explore the relationship between the visual field index (VFI) and the visual field mean deviation (MD) in glaucoma patients with moderately advanced perimetric damage and to identify the magnitude of the boundary effect of VFI that occurred when the VFI estimation strategy changed from pattern deviation probability value to total deviation probability value as the MD crossed −20 dB in longitudinal visual field (VF) series.Design: A retrospective cohort study of longitudinal data analysis.Methods: The MD and VFI values obtained from VF tests conducted on 148 eyes of 148 glaucoma patients having an MD around −20 dB were studied. A total (Read more...)
