What is wrong with Hillary Clinton’s eyes?

Several instances of her eyes not appearing to be acting in sync happened again during a rally in Cleveland, Ohio on Friday evening.

Her left eye seemed to turn more than her right while she strained to make a point as she was looking to her right.

Here are a few examples:

Clinton’s apparent eye problems first emerged during a rally in Philadelphia last month.

The same issue seemed to be occurring as she strained primarily while looking to her right.

After this incident, several doctors voiced their opinions publicly.

Writing for The Hill, Dr. John R. Coppedge observed:

It appears that she has a problem with her left sixth cranial nerve. That nerve serves only one function and that is to make the lateral rectus muscle contract. That muscle turns the eye in the direction away from the midline.

It comes out of the base of the brain and runs along the floor of the skull, immediately beneath the brain before coursing upward to the eye. Dysfunction of that muscle causes the striking picture of the eyes not aiming in the same direction and causes the patient to suffer double vision.

Like all things medical, there is a long list of potential causes but in my opinion the most likely one, based on Clinton’s known medical history is an intermittent lateral rectus palsy caused by damage to or pressure on her sixth cranial nerve.

“If, as is statistically likely, Clinton’s transverse sinus is still blocked,” Coppedge writes, “she would still have increased pressure and swelling and decreased blood flow to her brain. That swelling would place pressure on the exposed portion of the sixth cranial nerve at the base of her brain, explaining the apparent lateral rectus palsy. And such a deficit can be partial and/or intermittent.”
