The impact of metabolic syndrome on retinal findings in patients with erectile dysfunction.
OBJECTIVE
In the present study, we investigated the association between metabolic syndrome (MS) and retinal findings in patients presenting with erectile dysfunction (ED) complaints.


METHODS
A total of 102 patients with ED were included in this study. The patients were divided into two groups according to the National Cholesterol Education Program Adult Treatment Panel - III consensus definition: patients with MS (Group 1, n=62) and patients without MS (Group 2, n=40). The severity of ED was determined according to the first five versions of the International Index of Erectile Function. A detailed fundus examination was performed to evaluate the patients for retinopathy. The patients' retinopathy grades were classified according to the Early Treatment Diabetic Retinopathy Study.


RESULTS
The mean age of the patients was 51.4 years. Twenty-two patients (35.5%) in Group 1 and nine (22.5%) in Group 2 had severe ED (p=0.241). Ten (16.1%) patients in Group 1 and one (2.5%) patient in Group 2 had any degree of retinopathy (p=0.047). The logistic regression analysis of the correlation between severe ED and MS risk factors revealed that a fasting glucose level (FBG) of >110 mg/dL increased the risk of severe ED by 2.5 times (95% CI 1-6.2, p=0.058). Additionally, the logistic regression analysis of metabolic risk factors showed that only the FBS level was strongly associated with retinopathy, with the relative risk increased to 10.6 (95% CI 1.2-93, p=0.033).


CONCLUSIONS
Our results showed that elevated FBG levels were the most critical MS component in the development of severe ED and retinopathy.
