Idiopathic orbital inflammation is the third most common orbital disease, following Graves orbitopathy and lymphoproliferative diseases. We present a 11 year old girl with 15 days history of painless diplopia. There was no history of fluctuation of symptoms, drooping of eye lids or diminished vision. She had near total restricted extra-ocular movements and mild proptosis of the right eye. There was no conjunctival injection, chemosis, or bulb pain. There was no eyelid retraction or lid lag. Rest of the neurological examination was unremarkable.Erythrocyte sedimentation rate was raised with eosinophilia. Antinuclear antibodies were positive. Liver, renal and thyroid functions were normal. Antithyroid, double stranded deoxyribonucleic acid and acetylcholine receptor antibodies were negative. Repetitive nerve stimulation was negative. Magnetic resonance imaging (MRI) of the orbit was typical of orbital myositis. The patient responded to oral steroids. Orbital myositis can present as painless diplopia. MRI of orbit is diagnostic in orbital myositis.
特发性眼眶炎症是继格雷夫斯眼病和淋巴增生性疾病之后第三常见的眼眶疾病。我们报告一名11岁女孩，有无痛性复视15天病史。无症状波动、眼睑下垂或视力减退病史。她几乎完全限制了眼球运动，右眼轻度突出。无结膜充血、结膜水肿或眼球疼痛。无眼睑退缩或眼睑滞后。其余神经系统检查无异常。红细胞沉降率升高伴嗜酸性粒细胞增多。抗核抗体阳性。肝、肾和甲状腺功能正常。抗甲状腺、双链脱氧核糖核酸和乙酰胆碱受体抗体阴性。重复神经刺激阴性。眼眶磁共振成像（MRI）表现为典型的眼眶肌炎。患者对口服类固醇有反应。眼眶肌炎可表现为无痛性复视。眼眶MRI对眼眶肌炎具有诊断价值。
