Researchers identified a way of spotting cardiovascular disease in a patient by using a scan. Optical coherence tomography is commonly used to create images of the retina, the innermost light-sensitive layer of the eye.
The researchers examined lesions of the retina to determine if heart disorders could be detected.
Dr Mathieu Bakhoum, of the Shiley Eye Institute in San Diego, California, was the lead author of the study.
He said: “The eyes are a window into our health, and many diseases can manifest in the eye.”
Decreased blood flow caused by heart disease, can lead to inadequate blood flow to the eye and may cause cells in the retina to die, leaving a permanent mark.
The report is in the EClinicalMedicine journal.
