A new graphical procedure for topographical trend analysis (graphical analysis of topographical trends: GATT) is able to distinguish several possibilities of evolution of a visual field. Analysis of 100 cases with GATT made it possible to classified them into 10 types of development. This signifies an improvement over global statistical analysis, which distinguishes only 3 different types of evolution. In addition, the individual evaluation of visual field development with GATT is enhanced by quantitative and topographical differentiation within an evolutional type.
一种用于地形趋势分析的新图形程序（地形趋势图形分析：GATT）能够区分视野演变的几种可能性。对100例患者进行GATT分析后，可将其分为10种发展类型。这表明相较于仅区分3种不同演变类型的整体统计分析有了改进。此外，通过在一种演变类型内进行定量和地形区分，GATT对视野发展的个体评估得到了加强。
