Staging Glaucoma Patient: Why and How?

Abstract

Staging glaucomatous damage into appropriatecategories enhances management of the disease. Automated static perimetry is the benchmark for testing visual function in glaucoma. Numerous examples of standard automated perimetry staging systems have been proposed but difficulties such as lack of accuracy, absence of information related to location and depth of the defect(s) and need of time-consuming analysis of every visual field test result may reduce their day-to-day clinical usefulness.A new visual field staging system is proposed: the University of São Paulo Glaucoma Visual Field Staging System (USP-GVFSS). In this system, qualitative and quantitative characteristics of the visual field defect are described. The method is intuitive, comprehensible and describes severity, extension and hemi field involvement.
