RESUMO
Orbital varix is a relatively rare disease that causes exophthalmos due to increase of cerebral venous pressure. We experienced a forty-two-year-old male patient, who complained of intermittent exophthalmos and blurred vision. The diagnosis was based on clinical manifestation and various radiologic studies including computed tomography(CT), venography, and magnetic resonance imaging(MRI). MRI is a useful and safe diagnostic study through which we could observe the orbital varix and assess the relationship between the varix and the orbital structure. In this case, the varix is huge and attached to superior rectus muscle. There being many surgical risks, he has been followed up without surgical treatment and educated to modify the life pattern for prevention of increase of carotid venous presure.
