Outcomes of surgically treated rhinogenic optic neuropathy

Conclusion: The visual outcomes of endoscopic treatment of optic neuropathy are favorable. However, no specific prognostic factor was associated with good outcome. Objective: To investigate visual outcomes of patients with optic neuropathy caused by paranasal mucocele or sinusitis. Methods: The clinical course in 38 patients with rhinogenic optic neuropathy was investigated retrospectively. All patients underwent endoscopic sinus surgery and ophthalmologists measured preoperative and postoperative visual acuities. Results: Visual acuity completely recovered in 31 patients and partially in 2 patients, and did not recover in 5 patients. Age, sex, sinus involved (ethmoid or sphenoid), preoperative visual acuity, abnormal fundus findings, duration of symptoms, steroid use, and coexistence of diabetes mellitus showed no significant correlation with full recovery.
