Fig. 7. Comparison of static and kinetic perimetry to detect shallow scotomas and determine the slope of the scotoma. A. Kinetic evaluation can clearly outline the normal visual field. B. Kinetic perimetry may miss shallow scotomas and poorly define the flat slope seen nasally. C. The edge of steeply sloped scotomas may be identified easily with kinetic perimetry, but the steepness of the slope may not be appreciated. D and E. Static perimetry readily detects shallow scotomas and can define the slope of both shallow and steep scotomas. (Aulhorn E, Harms H: Early visual field defects in glaucoma.
