en General پژوهشي Research Article The present study reported the case of a 23-year-old female patient with right-sided enophthalmos. After several episodes of spontaneous periorbital ecchymosis, she developed positional proptosis. The ophthalmologic examination was normal, except a 3-mm enophthalmos measured using the Naugle exophthalmometer, which improved significantly by the Valsalva maneuvers. The diagnostic imaging tests in orbital disease consisting of orbital computed tomography and orbital magnetic resonance imaging showed a retro-orbital vascular lesion. The most likely diagnosis was orbital varix, which is a rare orbital vascular lesion. It was decided to manage the patient conservatively, in the absence of complications such as proptosis with corneal exposure, optic nerve compression, or unacceptable appearance.
