How Eye Examination Could Help in Detecting Brain Damage in Stroke Patients

A new study suggests that gadolinium used during MRI imaging in stroke patients leaks into the eyes and can provide clues about the stroke. The study was published in Neurology. The study evaluated the MRI (magnetic resonance imaging) reports of 167 stroke patients. Some patients did not receive treatment before the test while others were treated with the clot-dissolving drug called tissue plasminogen activator. The MRI was first done without and then with a contrast dye called gadolinium which was injected into the blood. The use of a contrast allows the easy detection of the damaged area of the brain.
