The clinical challenge often posed to neurologists is to diagnose parkinsonian patients with abnormal eye movements. As noted above, most patients with PD have normal eye movements for their age, whereas as most patients with PSP do not. In fact, a number of other parkinsonian disorders have been reported to produce abnormal eye movements, and it is those disorders that we review in this section, noting features that help to differentiate from PSP.
