Abstract. Purpose:To report a case of optic neuritis after gamma knife radiosurgery for pituitary adenoma. Case:A 41-year-old woman presented with impaired vision in both eyes since 5 days before. She had received surgery for pituitary tumor 5 years before. She was treated by gamma knife radiosurgery for relapse of tumor 50 days before. Her corrected visual acuity was 0.5 right and 0.6 left. She had abnormal color sense. Flicker fusion frequency was decreased in both eyes. Both eyes showed enlarged blind spot and relative scotoma in the superior sector. Magnetic resonance imaging(MRI)showed enhanced signal in the optic nerve sheath. These findings led to the diagnosis of optic neuritis. Pulsed corticosteroid therapy was followed by improved vision of 1.2 in either eye. She has been doing well for 18 months until present. Conclusion:This case illustrates that optic neuritis may develop after gamma knife radiosurgery.
