Acute optic neuropathy in Behçet disease.

PURPOSE: To report a patient with Behcet disease presenting with acute optic neuropathy.

METHODS

A 47-year-old man was admitted to the authors' clinic owing to sudden visual loss in the left eye. Ophthalmologic and systemic examinations were performed.

RESULTS

Visual acuity was 4/10 in the left eye. Fundus examination demonstrated swollen optic disc with blurred margins. There was relative afferent pupil defect in the same eye. Mega-dose corticosteroid treatment was started with the diagnosis of acute optic neuropathy. Ocular findings resolved within 2 weeks.

CONCLUSIONS

Behçet disease rarely presents with acute optic neuropathy.
