Dynamic Exophthalmos Secondary to an Orbital Varix

Abstract

We present a case of dynamic exophthalmos secondary to an orbital varix. Objectives of this paper are to describe this rare entity and review its etiology, diagnosis and treatment options. A 21-year-old woman presented complaining of exophthalmos in the right eye on bending forward. Neuroimaging studies revealed an irregularly shaped mass located in the posterior intra-extraconal region adjacent to the orbital roof. Surgical and interventional endovascular therapies were considered, but due to the complex nature of the lesion the patient was followed-up conservatively. Orbital varix may cause dynamic exophthalmos and most patients may be managed conservatively. Patients harboring non-treatable orbital varix should be advised to avoid any strenuous exercises and postures which may increase intraorbital pressure.
