The third and sixth cranial nerves are most frequently affected in diabetic extraocular
mononeuropathies. In diabetic oculomotor involvement the pupil is undisturbed. Of
the 21 patients of diabetic oculomotor paralysis 4 patients (19 percent) had dilated
unreactive pupil suggestive of pupillomotor involvement. No other cause could be attributed
to oculomotor paralysis. These patients showed complete but slow resolution as compared
to those without pupil involvement.
