Following on the heels of recent studies showing gadolinium retention in the body following the use of contrast agents in MRI, a new study reveals involvement of the eye. In a National Institutes of Health (NIH) sponsored study, published in ‘Neurology’ on Feb. 7, 2018, 167 patients with acute stroke were studied following MRI of the brain. Patients were selected who had an MRI with gadolinium at baseline and another MRI with fluid-attenuated inversion recovery (FLAIR) imaging at 2 and/or 24 hours later. Leakage of gadolinium into the eye was found in 76% of the patients. After a 2-hour follow-up examination, leakage was found in 67% in the aqueous chambers of the eye, compared to 6% of participants who showed evidence of leakage in the vitreous chambers. Twenty-seven per cent of patients had leakage in both chambers. The aqueous chamber is the fluid-filled space inside the eye between the iris and the cornea's innermost surface. The vitreous chamber is located behind the lens and in front of the optic nerve. The fluid in both chambers is crucial for normal vision.
