Sixth Nerve

Dolichoectasia refers to distinct elongation, dilatation and tortuosity of an artery. We present a rare well-illustrated case of dolichoectatic vertebrobasilar artery compressing the cisternal portion of the sixth cranial nerve resulting in chronic sixth nerve palsy. High spatial resolution, three-dimensional, heavily T2-weighted MRI sequences are uniquely positioned to assess the cranial nerves especially in their cisternal and canalicular portions and need to be performed for all patients with non-resolving cranial nerve palsies. Dolichoectatic vessels can be the cause of neurovascular conflict and cause non-resolving oculomotor palsies.

The Impact

OBJECTIVEThe precise threshold differentiating normal and elevated intracranial pressure (ICP) is variable among individuals. In the context of several pathophysiological conditions, elevated ICP leads to abnormalities in global cerebral functioning and impacts the function of cranial nerves (CNs), either or both of which may contribute to ocular dysmotility. The purpose of this study was to assess the impact of elevated ICP on eye-tracking performed while patients were watching a short film clip.METHODSAwake patients requiring placement of an ICP monitor for clinical purposes underwent eye tracking while watching a 220-second continuously playing video moving around the perimeter of a viewing monitor. Pupil position was recorded at 500 Hz and metrics associated with each eye individually and both eyes together were calculated. Linear regression with generalized estimating equations was performed to test the association of eye-tracking metrics with changes in ICP.RESULTSEye tracking was performed at ICP levels ranging from −3 to 30 mm Hg in 23 patients (12 women, 11 men, mean age 46.8 years) on 55 separate occasions. Eye-tracking measures correlating with CN function linearly decreased with increasing ICP (p < 0.001). Measures for CN VI were most prominently affected. The area under the curve (AUC) for eye-tracking metrics to discriminate between ICP < 12 and ≥ 12 mm Hg was 0.798. To discriminate an ICP < 15 from ≥ 15 mm Hg the AUC was 0.833, and to discriminate ICP < 20 from ≥ 20 mm Hg the AUC was 0.889.CONCLUSIONSIncreasingly elevated ICP was associated with increasingly abnormal eye tracking detected while patients were watching a short film clip. These results suggest that eye tracking may be used as a noninvasive, automatable means to quantitate the physiological impact of elevated ICP, which has clinical application for assessment of shunt malfunction, pseudotumor cerebri, concussion, and prevention of second-impact syndrome.
