In addition to the above, if mass effect is present with resulting displacement of brain tissue, additional signs may include pupillary dilatation, abducens palsies, and the Cushing's triad.

The abducens nucleus along with the internal genu of the facial nerve make up the facial colliculus, a hump at the caudal end of the medial eminence on the dorsal aspect of the pons.
23.
A pituitary tumour may also extend into the cavernous sinus, compressing the oculuomotor nerve ( III ), trochlear nerve ( IV ) and abducens nerve ( VI ), leading to double-vision and strabismus.
24.
Focal neurological deficits may also occur, such as abducens nerve palsy and vertical gaze palsy ( Parinaud syndrome due to compression of the quadrigeminal plate, where the neural centers coordinating the conjugated vertical eye movement are located ).
25.
Unlike the nerves listed above, the abducens nerve ( CN VI ) does not run within the lateral wall of the cavernous sinus; rather, it runs through the middle of the sinus alongside the internal carotid artery.
26.
Abducens nerve palsy is also known to occur with halo orthosis placement . The resultant palsy is identified through loss of lateral gaze after application of the orthosis and is the most common cranial nerve injury associated with this device.
27.
As far as the non-wiki stuff you brought up, I was banned from the Outpost because I protested the treatment of Abducens ( who by the way, was ultimately reinstated, but refused to return ).
28.
The control of conjugate gaze is mediated in the brainstem by the medial longitudinal fasciculus ( MLF ), a nerve tract that connects the three extraocular motor nuclei ( abducens, trochlear and oculomotor ) into a single functional unit.
29.
The central anatomy of the sixth nerve predicts ( correctly ) that infarcts affecting the dorsal pons at the level of the abducens nucleus can also affect the facial nerve, producing an ipsilateral facial palsy together with a lateral rectus palsy.
30.
Internuclear ophthalmoplegia occurs when MS affects a part of the brain stem called the medial longitudinal fasciculus, which is responsible for communication between the two eyes by connecting the abducens nucleus of one side to the oculomotor nucleus of the opposite side.
