To study the demographic pattern and clinical characteristics of optic neuritis cases in a tertiary eye care centre in Nepal.
Descriptive, cross-sectional study.
Complete ocular examination was done in all the newly diagnosed cases of optic neuritis presenting from January 1st 2012 to June 30th 2013. Demographic pattern, clinical features, visual acuity, colour vision, contrast sensitivity and visual field defects were studied.
Sixty seven eyes of 50 patients (28 females and 22 males) with optic neuritis were included in the study. The mean age was 34.32 years ± 13.72 years. The male: female ratio was 1:1.27. All the cases presented with complaint of blurring of vision. Painful ocular movement was noted in 58%. On ophthalmoscopic examination around 2/3rd of eyes suffered from papillitis (72%) and 1/3rd from retrobulbar optic neuritis (27%). Only one case of neuroretinitis (1%) was seen in the study. The colour vision pattern was variable. Contrast sensitivity was reduced in 94%. Centrocaecal scotoma was seen in 10.5%.
Females were predominantly affected. Unilateral involvement was the most common presenting as papillitis.

描述性横断面研究。
对2012年1月1日至2013年6月30日期间所有新诊断的视神经炎病例进行全面的眼部检查。研究人口统计学模式、临床特征、视力、色觉、对比敏感度和视野缺损情况。
本研究纳入了50例（28例女性和22例男性）视神经炎患者的67只眼。平均年龄为34.32岁±13.72岁。男女比例为1:1.27。所有病例均有视力模糊的主诉。58%的病例出现眼球运动疼痛。眼底检查发现，约2/3的眼患有视乳头炎（72%），1/3患有球后视神经炎（27%）。本研究仅发现1例神经视网膜炎（1%）。色觉模式各异。94%的患者对比敏感度降低。10.5%的患者出现中心暗点。
女性受影响更为显著。单侧受累最为常见，表现为视乳头炎。
