Methods

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.
