Practical Recommendations for Measuring Rates of Visual Field Change in Glaucoma

Statement of Interest Assessment of visual field damage is the major index of the functional impact of glaucoma with direct relevance to quality of life measures. Visual field change was used as a primary endpoint for progression in the recent glaucoma trials and its measurement is the cornerstone of glaucoma management influencing therapeutic decisions. The objective of this perspective is to provide practical recommendations for measuring clinically relevant rates of glaucomatous visual field progression to help identify patients at risk for visual impairment. They focus on the frequency of examinations required for detecting various amounts and rates of visual field change.
