[Procedures for the quantitative follow-up control of computerized perimetric findings in glaucoma]

A statistical model for long-term follow-up of glaucomatous visual fields is described. Using an analysis of individual testpoints, a statistical evaluation of visual field change is done by the Bowker symmetry test. Eccentricity of test points in the visual field, density of scotomas and number of defective test points were used as parameters. The authors demonstrate that evaluation with this method is superior to methods using total sensitivity loss or mean sensitivity of the visual field. This model is currently being used in a retrospective and a prospective glaucoma study.
