[Conventional techniques of visual field examination: part 4 Static perimetry: interpretation--perimetric indices--follow-up--perimetry in childhood].
Visual field examination with fixed stimuli was first realized in manual static profile perimetry. The transition from a linear stimulus alignment along a profile section towards a two-dimensional arrangement introduced the era of static grid perimetry. Application of computer technology nowadays allows automation and standardization of this procedure, which enables the examiner to select the necessary visual field area, the adequate grid, and the optimal strategy for an estimation of differential luminance sensitivity. Furthermore, the computer independently takes over the recording, visualization, and processing of the perimetric procedure. This contribution discusses conventional static visual field examinations since these are widely used, easily accessible, well established for practical application, and standardized. This paper (part 4) explicitly focuses on the correct interpretation of automated static strategies of visual field examinations. Furthermore the classification and scoring of visual field defects as well as quality control, progression analysis, and perimetry in childhood are addressed. This manuscript is based on three preceding parts, which were published in previous issues of this journal [27, 28, 29].
