B型超声对眼外肌的观察

Observation of extraocular muscle with B-mode ultrasound

摘要:

目的:了解正常人及不同眼外肌疾病患者的眼外肌B型超声的图像特点。方法:回顾性分析我院2007-10/2010-10间利用10MHzB型超声进行眼外肌检查的情况,归纳总结正常人群眼外肌的厚度以及不同眼外肌疾病B超声像图特点。结果:正常人群双眼对称眼外肌厚度无明显差别;4条直肌中,内直肌最厚;20岁之前4条眼外肌厚度随年龄增大而增厚。不同眼外肌疾病眼外肌B超表现各不相同。结论:B型超声可以较好的显示4条眼外肌的形态,便于眼外肌疾病的随诊观察。B型超声是检查眼外肌的有效手段。

Abstract:

AIM:To understand extraocular muscles image features in B-mode ultrasound.METHODS:The extraocular muscles on normal persons and different extraocular muscle diseases were observed using B-mode ultrasound from Oct.2007 to Oct.2010.RESULTS:Symmetric extraocular muscle thickness had no significant difference in normal eyes,the medial rectus was the thickest muscle among four rectus;before the age of 20,four extraocular muscles thickness increased with age.Different extraocular muscle diseases had different performance in B-mode ultrasound.CONCLUSION:B-mode ultrasound can show good form of four extraocular muscles and it is benefit for follow-up observation of extraocular muscle disease.B-mode ultrasound is an effective means of checking extraocular muscles.
