Optic neuritis: characteristics and visual outcome



Optic neuritis: characteristics and visual outcome



Journal of the Medical Association of Thailand 86(3): 238-243



To determine clinical characteristics of patients with optic neuritis and visual outcome after intravenous methylprednisolone treatment. A total of 81 patients with optic neuritis were reviewed retrospectively with regard to their clinical characteristics by dividing into two groups as follows: group I had isolated optic neuritis and group II had optic neuritis with demyelinative disease. The visual outcome in these patients before and after intravenous methylprednisolone treatment was analyzed. Of 81 patients with optic neuritis, 63 patients (77.8%) had isolated optic neuritis and 18 (22.2%) patients were optic neuritis with demyelinative disease. The ages of the patients ranged from 16 to 59 years (mean = 35.3 years) in patients with isolated optic neuritis and from 16 to 73 years of age (mean = 35.8 years) in patients with optic neuritis with demyelinative disease. After treatment, 45 patients (52 eyes) with isolated optic neuritis and 14 patients (25 eyes) with optic neuritis with demyelinative disease who were followed-up for more than 10 days were studied. After treatment, 60 per cent of the isolated optic neuritis patients and 24 per cent of the optic neuritis patients with demyelinative disease had a visual acuity of 6/12 or better respectively. The isolated optic neuritis who had an onset interval to treatment of less than 8 days had a visual acuity better than 6/9 in 75 per cent. The final visual outcome in patients with isolated optic neuritis who received earlier treatment was better than those who received treatment later.
