Radiation Optic Neuropathy (RON) is a devastating complication of radiation therapy to the head, orbit, or paranasal sinuses, causing irreversible vision loss. It typically occurs 6 months to 3 years after radiation exposure, when the total dose exceeds 50 Gy. The condition results from radiation-induced damage to the optic nerve vasculature, leading to ischemic injury and optic nerve atrophy.
