Holmes JM, Leske DA, Christiansen SP. The nerve dysfunction induces esotropia, a convergent squint on distance fixation. Partial lateral rectus function is associated with a smaller primary gaze esotropia and retained ability to abduct to the midline and beyond (Figure 7), but the preservation of some sixth nerve function raises the possibility of other confounding diagnoses (Table 3).

Demer JL, Clark RA, Kono R, Wright W, Velez FG, Rosenbaum AL. have As the VIth nerve passes through the subarachnoid space it lies adjacent to anterior inferior and posterior inferior cerebellar and basilar arteries and is therefore vulnerable to compression against the clivus.
