SUMMARY

The pathological findings of pupil-sparing oculomotor palsy in a diabetic patient are presented and discussed in view of the 2 other published necropsy studies of this disorder. Intraneural arteriolar abnormalities were seen in all 3, but our patient was the first in whom the pathological neural process involved the subarachnoid segment of the third nerve.
