Despite being relieved of the stresses of a presidential campaign, Hillary Clinton’s apparent eye problems reoccurred during a welcome video she produced for the Democratic National Committee meeting on Friday.

Clinton provided a nearly three-and-a-half minute video urging Democrats to fight Trump’s agenda for America.

“We as Democrats must move forward with courage, confidence and optimism, and stay focused on the elections we must win this year and next,” Clinton said.

“Let resistance plus persistence equal progress for our party and our country.”

A close examination of the video shows Clinton’s eye problems — which appeared while she was on the campaign trail — are still evident.

At several points in the video, Hillary’s eyes were not in sync, a condition at least one doctor said can be caused by brain swelling and can lead to double vision.

While Clinton was seen numerous times with her eyes not appearing to be in sync with one another during the fall campaign, the worst example came during a September speech to students at Temple University in Philadelphia.

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

After that 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.”
