Methods Twenty-seven patients with orbital inflammatory pseudotumor, of which 12 were myositis, 7 were diffuse, 3 were posterior and 5 were anterior. Gradually taper after 2 weeks, 20 ~ 30 days after the withdrawal. After discontinuation of small doses of radiation therapy (cobalt-60 orbital foramen lateral orbital irradiation, the total 20Gy, 2 weeks, 10 times given, 2Gy / times). Results The patients were followed up for 3 years. Twenty-seven patients (85%) had eye pain, prominent eyeballs and eye movement disorders disappeared after the above comprehensive treatment. Among them, 2 cases were partly relieved (74%), while 2 were ineffective Cases, accounting for 74%; 3 years follow-up, no recurrence in 23 cases. Conclusions The combination of corticosteroids and low dose radiation therapy can significantly reduce the clinical symptoms of patients with orbital inflammatory pseudotumor, improve the cure rate and reduce recurrence
