目的分析后天性麻痹性斜视的常见病因。方法对64例复视患者的临床资料进行回顾性研究。分析复视的病因,各年龄组病因特点,受累眼外肌分布情况。结果20-50岁发病率最高,占48.44%,其病因以外伤和甲状腺相关眼病居多,分别为25.81%、22.58%;50岁以上占35.93%,以血管性疾病为主,占52.17%;20 岁以下占17.18%,以外伤和重症肌无力为主,均为36.36%。眼外肌及颅神经受累情况,外展神经麻痹最多占32.87%,其后依次为复合神经麻痹,占18.75%,内直肌15.62%,上斜肌和上直肌各10.93%。结论发病原因中以血管性疾病和甲状腺相关眼病(Graves病)占多数,而从受累部位来看,外展神经占首位,而且不同年龄的致病因素不尽相同。
Objective To analyze the common causes of acquired paralytic strabismus. Methods The clinical data of 64 patients with diplopia were retrospectively studied. Analysis of the etiology of diplopia, etiology and characteristics of each age group, affected the distribution of extraocular muscle. Results The highest incidence was 20-50 years old, accounting for 48.44%. The causes of traumatic and thyroid-related ophthalmopathy were 25.81% and 22.58% respectively, 35.93% were over 50 years old, and vascular diseases accounted for 52.17%. Under the age of 17.18%, mainly with trauma and myasthenia gravis, were 36.36%. Extraocular muscles and cranial nerves involved the most cases, with 32.87% of abducens nerve palsy, followed by composite paralysis, accounting for 18.75%, 15.62% of rectus abdominis and 10.93% of upper rectus and superior rectus muscle respectively. Conclusion The causes of vascular diseases and thyroid-related eye disease (Graves disease) accounted for the majority, but from the affected parts, the top of the abducens nerve, and different age-related risk factors vary.
