Bilateral Retinal Vein Occlusion-Simulated Coats’ Disease

Retinal vein occlusion (RVO) is a differential diagnosis for Coats’ disease due to retinal arterial Leber’s aneurysms. Occasionally, RVO shows a Coats-like appearance. The differential diagnosis between Coats’ disease and RVO is essential for clinical therapy, especially for those obsolete RVOs with collateral vessels and without retinal hemorrhage. In this case report, we describe and discuss the imaging characteristics of bilateral RVO-simulated Coats’ disease with tortuous retinal arterioles and its prognosis after anti-vascular endothelial growth factor therapy, which will be beneficial for its definite diagnosis and aid further investigation.
