Estimating glaucomatous anatomical damage by computerized automated perimetry.

The ability of two methods (the Glaucoma Staging System and the Functional Score index) in estimating anatomical damage from automated visual field data was studied in 100 patients with chronic open-angle glaucoma. The level of association between functional and anatomical loss (classified by cup/disk ratio assessment) was satisfactory in both systems. Both the GSS (Glaucoma Staging System) and the FS (Functional Score) could be useful for estimating and quantifying the glaucomatous anatomical damage, both in the day-to-day clinical practice and in research.
