2013, Vision ResearchCitation Excerpt :Finally, although nystagmus with an amplitude of 1 deg or more is visible by clinical observation, extended periods of eye-movement recording can be useful to document if the direction of the nystagmus fast phase changes over time. A periodic change in the direction of the fast phase influences the choice of a possible surgical intervention in patients with infantile nystagmus (Gradstein et al., 1997; Hertle et al., 2003) and provides diagnostic information in patients with acquired nystagmus (Leigh & Zee, 2006; Shallo-Hoffmann & Riordan-Eva, 2001). The documentation of tiny amplitudes of acquired nystagmus, which may not be readily visible even in a careful clinical examination, can provide an explanation for worrisome symptoms, such as blur and oscillopsia.
Nystagmus and saccadic intrusions
2011, Handbook of Clinical NeurologyCitation Excerpt :In congenital forms of PAN, the reversal of the nystagmus is much less regular in timing. Furthermore, the slow phases show an increasing-velocity profile, as is typical for other congenital forms of nystagmus (Abadi and Pascal, 1994; Gradstein et al., 1997; Shallo-Hoffmann et al., 1999; Shallo-Hoffmann and Riordan-Eva, 2001). Acquired PAN can occur in association with a number of conditions (Table 13.5), many of which involve the cerebellum.
