Optic nerve sheath fenestration (ONSF) is a well-known, relatively safe, and effective surgical treatment for visual loss related to papilledema. Visual loss following ONSF is uncommon but can occur from direct surgical trauma, ischemic optic neuropathy, orbital or intrasheath hemorrhage, or arterial occlusion. Transient severe (e.g., light perception (LP) or no light perception (NLP) visual loss) after ONSF is uncommon but has been reported. We describe a case of LP vision following uncomplicated ONSF with orbital imaging demonstrating significant postoperative inflammation and slow recovery after intravenous steroid treatment. We discuss the various mechanisms for this phenomenon after ONSF. To our knowledge, this is the first clinico-radiologic description with follow up and recovery of this postoperative complication of ONSF to be reported in the English language ophthalmic literature.
