title: Optic neuropathy following endovascular coiling of an orbital varix.
abstract: Orbital varices are vascular malformations consisting of abnormal venous channels. Indications for intervention include loss of vision, elevated orbital pressure with motility deficit, and intractable pain. We present a case of a 65-year-old woman with an orbital varix, who underwent embolization via endovascular coiling. This treatment resulted in an intralesional thrombosis with subsequent enlargement of the varix, leading to a compressive optic neuropathy and severe vision loss. If an intervention is to be contemplated, the possibility of this rare but serious complication should be carefully considered and patients appropriately counseled.
