Temporal Response Properties of Optic Neuritis Patients Manifesting Statokinetic Dissociation (SKD)

Abstract

Statokinetic dissociation (SKD) refers to a greater impairment for detecting stationary targets (e.g., static perimetry) relative to detecting moving targets (e.g., kinetic perimetry). Riddoch (1917) originally described this phenomenon in a small group of patients with post-chiasmal lesions, although Zappia, Enoch, Stamper and Winkelman (1971) subsequently reported its presence in several cases of chiasmal disorders and optic neuropathies. Recent investigations (Safran and Glaser, 1980; Johnson and Keltner, 1980; Wedemeyer, Johnson and Keltner, 1989) indicate that SKD is probably most prevalent in optic nerve disease, particularly optic neuritis.
