Radiation Optic Neuropathy Treatment in Seal Beach, California

Medically reviewed by Dr. Alexander Bonakdar, O.D. · Updated February 2026

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.

Seal Beach's coastal environment can influence how radiation optic neuropathy presents and responds to treatment. Factors like UV exposure, wind, and marine air quality are considered in our evaluation and management approach.
