Abstract

Clinical automated static perimetry for glaucoma typically measures white-on-white increment thresholds for a grid of locations throughout the central visual field.^1,2 Relative scotomas (regions of the visual field for which threshold is abnormally high) are early signs of glaucomatous damage. Increase in number, size or depth of relative scotomas is an indication of progression of glaucomatous damage. Surgical reduction of intraocular pressure (IOP) to subnormal levels can halt progression of perimetric defect for several years even in cases of extreme damage.³
