For those in the habit of getting their neck adjusted by a chiropractor, the University of Michigan Kellogg Eye Center has interesting information to know about: High velocity neck manipulation has been shown to result in stress on the eye and lead to spotty vision.
The risk is rare, but one that Yannis Paulus, M.D., a retina specialist at Kellogg, reports on in the American Journal of Ophthalmology Case Reports.
The energetic thrusts and rotations sometimes performed in high-velocity neck manipulation have been linked to damage to the blood vessels in the retina. Resulting abnormal bleeding inside the eye may also cause vision loss.
This was the case for a 59-year-old woman who experienced a “tadpole” shaped spot in her vision while driving home from a chiropractor visit — with her sight worsening the next day. She had just received cervical spine manipulation using the high-velocity technique to help with her headaches.
