Introduction: Optic neuritis is an inflammation of the optic nerve that usually affects young females. In Western countries, natural history and treatment of optic neuritis(ON) has been studied extensively. However aetiology, natural history, clinical features of ON and their relation to multiple sclerosis in Asian population needs to be defined yet. Methods: 30 patients who were diagnosed as optic neuritis were included between June 2013 to December 2014 at BP Koirala Lions Centre for Ophthalmic Studies (BPKLCOS). A detailed history was obtained followed by examination of anterior and posterior segment. Assessment of visual acuity, color vision, contrast sensitivity, visual evoked potential (VEP),visual field and MRI of orbit and brain was done in all cases. All patients were treated with intravenous Methylprednisolone 500mg twice daily for 3 days followed by oral steroid for 11 days which was tapered in the next 4 days.The patients were reassessed at 2 weeks, 1 month and 3months. Results: Commonest presenting symptom was diminution of vision(65%). MRI showed multiple paraventricular oval plaques definite of multiple sclerosis in one patient and one was diagnosed as probable MS who had a single periventricular plaque. Visual evoked potential (VEP) showed increase in the mean P100 latency at 60’ and reduction in amplitude in eyes affected with optic neuritis compared to normal eyes. At 3 months follow up, 70% had good visual recovery (>6/18). The cause of non-improvement in vision was disc pallor. Optic disc pallor was detected in 37.5% of the eyes during follow up. Conclusions: Good visual recovery was observed in most eyes with acute optic neuritis. Multiple sclerosis was seen in 1 patient who had recurrent optic neuritis.
