Introduction: Retinal vein occlusion is a common vascular disorder disrupting vision. Two basic types of RVO are branch retinal vein occlusion and central retinal vein occlusion (CRVO).Retinal vein occlusion is a multifactor process including systemic illness and local retinal factors.RVO may be associated with atherosclerotic risk factors. We analyzed the role of 2 dimensional transthoracic echocardiography (TTE) for detecting the cardiac disease in patients with retinal veins occlusion. Materials and Methods:In this cross-sectional study 70 recently diagnosed patients with RVO enrolled in the study. The clinical diagnosis of retinal vein occlusion and its type was confirmed by a vitreoretinal specialist. The Patients were then referred for performing complete TTE. Results: The prevalence of RVO increased with age, but did not vary by sex. The most frequent cardiovascular risk factor was hypertension. The findings of our study revealed that a variety of echocardiographic abnormalities may be presented in patients with RVO. Diastolic dysfunction was the most frequent echocardiographic finding and we found positive correlation between diastolic dysfunction with increasing age and the presence of hypertension. Other findings included mitral regurgitation (52.9%), mitral stenosis (2.9%), mitral annulus calcification (1.4%), mitral valve prolapse (8.6%), aortic insufficiency (22.9%), sclerotic aortic valve (27.1%), tricuspid regurgitation (45.7%), pulmonary insufficiency (8.6%), mild pulmonary hypertension (8.6%), and moderate to severe pulmonary hypertension (4.3%) Mild LVH (11.4%), Moderate LVH (8.6%). Abnormality on IAS was defined in these patients, including paten foramen ovale, lipomatosis IAS, exaggerated motion of IAS, and aneurysm of IAS. Conclusion: In our study, the most common echocardiographic finding was diastolic dysfunction which was compatible with the patients' age and the fact that the most prevalent risk factor was hypertension. Other findings were not more prevalent than general population.We think that a routine workup for structural heart diseases is unwarranted in these patients.
