The detection of true visual field deterioration in glaucoma is of fundamental importance but is limited by inherent variability of the measurements. New techniques have been developed that use powerful statistical regression analysis methods to objectively quantify progression of visual field defects. These have been combined with new methods of graphical presentation to reveal the spatial distribution in the visual field of deterioration. New measurement techniques utilizing blue-on-yellow, flicker, and motion stimuli provide further advantages and may be combined with regression analysis to improve the early detection of real progression of visual field loss.
