Purpose: This study aims to evaluate the association between age-related macular degeneration (AMD) and cardiovascular disease by using the noninvasive flow-mediated dilation (FMD) test to show endothelial dysfunction as an indicator of subclinical atherosclerosis. Method: Participants in this study included 30 dry AMD patients, 30 wet AMD patients, and 30 healthy controls without any systemic disease, including AMD. FMD and the intima media thickness (IMT) of the carotid artery were compared between the groups. Results: Comparison of FMD between the groups showed a 10.96% brachial artery dilation in the healthy controls, 3.99% in the dry AMD group, and 5.03% in the wet AMD group. While a significant difference was not observed between the wet and dry AMD groups, comparison of the control group to the wet and dry AMD groups yielded a significant difference. When brachial artery dilation below 7% was accepted as an abnormal FMD, 26.7% of the healthy controls, 66.7% of the dry AMD patients and 76.7% of the wet AMD patients were found to be abnormal. Similarly, while no significant difference was observed between the wet and dry AMD groups, comparison of the control group with the wet and dry AMD patients yielded a significant difference. When an IMT below 0.7 mm was accepted as abnormal, 26.7% of the healthy controls, 33.3% of the dry AMD, and 43.3% of the wet AMD were found to have an abnormal IMT. However, differences between the groups did not reach statistical significance. Conclusions: In this study, use of the FMD test showed endothelial dysfunction among AMD patients. No significant differences were found between the dry and wet AMD patient groups.
