Signs of meningeal irritation may be present; therefore, meningitis must be excluded. CN V1 (with ciliary ganglion) sends branches to the tentorium (the recurrent nerve of Arnold), as well as to CN III, CN VI, and occasionally CN IV. This may account for the frequency of meningeal signs and the occasional CN III and CN VI nerve palsies associated with HZO.
