The limitations of kinetic perimetry in early scotoma detection.

When tested by Goldmann kinetic perimetry ten patients with glaucomatous optic disc cupping had no visual field defects, but visual field defects were detected when tested by threshold static perimetry on the Tubingen perimeter. To improve the detection ability of kinetic perimetry, we suggest placing the interisopter spot-checks close together or expanding the central 30 degrees plotting area.
