Atrial fibrillation's eye impact
A recent study has revealed that subtle changes in some layers of the retina may be linked to atrial fibrillation, a heart rhythm disorder that increases the risk of stroke by five times. The findings suggest that thinning of the retinal layers, especially the neural layer responsible for transmitting visual information, can be observed approximately four years before the clinical diagnosis of the disease. Although eye examination does not directly diagnose atrial fibrillation, it can serve as a useful tool in identifying individuals who need further cardiac evaluations, particularly those with risk factors such as high blood pressure and diabetes. The study emphasizes the importance of early detection, as atrial fibrillation can be treated by regulating heart rhythms and reducing the risk of blood clots and stroke.
