Walsh & Hoyt: Acquired

As with oculomotor and trochlear nerve palsies, many series report a variety of causes of abducens nerve palsy. These articles have the same limitations as those described with respect to other ocular motor nerve palsies. Nevertheless, certain specific syndromes do occur, depending on the location and nature of the lesion producing the palsy. Lesions of the abducens nerve nucleus. Lesions of the abducens nerve fascicle. Lesions of the abducens nerve in the subarachnoid space. Lesions of the extradural portion of the abducens nerve at the petrous apex. Lesions of the abducens nerve in the cavernous sinus and superior orbital fissure. The sphenocavernous syndrome. Lesions of the abducens nerve within the orbit. Lesions of the abducens nerve of uncertain or variable location. Chronic, isolated abducens nerve paralysis.
