Properties of the Statpac Visual Field Index
Investigative Opthalmology & Visual Science, 2011 Purpose. To compare the properties of the visual field index (VFI) to those of mean deviation (MD) in patients with glaucoma. Methods. MD and VFI were calculated in data obtained from an ongoing longitudinal study in which patients with glaucoma (N = 109, 204 eyes) were observed for 9.8 years (median, 21 tests) with static automated perimetry.

“Over London at Night”: Gasworks, Ballooning, and the Visual Gas Field
British Art Studies, 2022 In 1865, the scientist James Glaisher described the way that gaslights illuminated the outline of the serpentine river Thames when seen from a balloon: “On leaving Charing Cross I looked back over London, the model of which could be seen traced—its ...

Clinical Validation of Visual Field Index
Journal of the Korean Ophthalmological Society, 2010 Purpose: To determine the associations of visual field index (VFI) with advanced glaucoma intervention study (AGIS) score, mean deviation (MD), pattern standard deviation (PSD), and average retinal nerve fiber layer (RNFL) thickness as measured by optical coherence tomography (OCT) and to evaluate the diagnostic abilities of these parameters.

Behavior of Visual Field Index in Advanced Glaucoma
Investigative Opthalmology & Visual Science, 2013 To evaluate the magnitude of Visual Field Index (VFI) change attributable to change in the estimation algorithm from the pattern deviation probability plot (PDPP) to the total deviation probability plot (TDPP) when the mean deviation (MD) crosses -20 decibels (dB).In a retrospective study, 37 stable glaucoma eyes in which MD of the VFs crossed -20 dB ...
