Quantifying the signal/noise ratio with perimetric stimuli optimised to probe changing spatial summation in glaucoma [Abstract]

Purpose : Guided by changes in spatial summation in glaucoma, we undertook a cross-sectional prospective study to compare disease signal, response variability, and signal/noise ratio (SNR) between perimetric stimuli varying in area, contrast, and both simultaneously, in patients with glaucoma and age-similar healthy controls. Methods : Participants were 30 glaucoma patients (median [interquartile range] age: 70.4 years [66.2, 73.5], MD:...
