[Rhinogenous retrobulbar optic neuritis: a case report].
Rhinogenous retrobulbar optic neuritis is characterized by neuritis secondary to paranasal sinusitis. A case of rhinogenous retrobulbar optic neuritis that was successfully treated by surgery is reported. A 40-year-old man complained of progressive right visual disturbance. The clinical course and neurological examination suggested right retrobulbar optic neuritis. CT and MRI scans demonstrated a massive tumor-like lesion near the right optic canal. Fifteen days after the onset, decompression of the right optic nerve was performed using a right pterional approach. After surgery, visual disturbance improved, and after about 1 month, the symptom had disappeared. Operative findings, histological examination and the postoperative course were consistent with the characteristics of rhinogenous retrobulbar optic neuritis. We consider decompression of the optic nerve to be effective for the treatment of rhinogenous retrobulbar optic neuritis.
