The patient’s pupil reactions should be evaluated by shining a bright light into each eye. This checks the neurological integrity of the connections between the optic nerve and the brain, and many optic nerve diseases (including advanced glaucoma and ischemic optic neuropathy) may be first detected this way. Many diabetics are found to have sluggish pupil responses, and this suggests some degree of autonomic neuropathy affecting Cranial Nerve III.
The patient also is asked to follow a moving target with her eyes only, which allows the doctor to evaluate the function of the six extra-ocular muscles and assess any possible paresis or double vision from diabetic nerve palsy
