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.
