FIGURE 6.

Comparison of the characteristics with isolated trochlear and abducens nerve palsy. (a) The etiological distribution of isolated oculomotor nerve palsy differed from those of isolated trochlear and abducens nerve palsies in the same cohort reported previously (p < 0.001). (b) Patients with isolated oculomotor nerve palsy more frequently visited the emergency department first than trochlear or abducens nerve palsy (p < 0.001). (c) The proportion of involved specialties differed amongst the isolated ocular motor nerve palsies. For all three nerve palsies, the ophthalmologists were mostly involved in the management, especially for trochlear nerve palsy. In contrast, the neurologists were more frequently involved in the care of oculomotor and abducens nerve palsies than trochlear palsy.
