Macular degeneration linked to stroke risk

Individuals with early age-related macular degeneration (AMD) have almost twice the risk for stroke as those without the disease, a new study has found.

AMD is a degenerative condition of the retina at the back of the eye. The central or macular part of the retina becomes worn and damaged, resulting in distorted or fuzzy vision. It is the most common cause of blindness in individuals aged 40 years and over.

The new study looked at 10,000 people aged between 49 and 73 with no history of stroke or coronary heart disease. Results showed that those with early stage AMD had a higher incidence of stroke than those without AMD.

Based on these findings, the researchers suggest that people with this eye condition should also be monitored for stroke risk.

Researchers had previously thought that there was a link between AMD and cardiovascular disease because they share many of the same risk factors, but this is the first study to show a link between the 2 conditions.

Remember: There may be a relationship between early AMD and increase stroke risk. Have your eyes checked regularly and discuss any changes with your GP.
