摘要
目的:为评价眼型Graves病视神经病变影像学诊断提供形态学基础。方法:在15个防腐固定成人尸头的颅前窝底上作9个连续冠状断面,观测眼球后第2~5断面眼直肌的宽、厚、断面面积之和与眶断面面积的比率及水平肌厚度之和与眶宽的比率。结果:在第 2~5断面上,眼直肌断面面积之和与相应眶断面面积的比率(x±s%)分别为:22±4、29±4、24±3、14±2。水平肌厚度之和与相应眶宽的比率(x±s%)分别为:37±5、40±7、35±4、26±3。结论:在第3断层上利用此2个比值可预测眼型Graves病视神经病变发生的可能性。
Objective:To provide morphological basis for imageologic diagnosis of the developing likelihood of optic neuropathy in Graves' Ophthalmopathy.Methods:On the anterior cranial fossa of 15 antiseptic fixed cadaveric heads specimens,9 successive orbital coronal planes were made. The width, thickness of rectus m. and the ratio of the area of rectus m. to the area of orbit as well as the ratio of the total thickness of the horizontal m. to the corresponding width of orbit on aection 2 ~ 5 were observed and measured . Results: The ratio of the area of rectus m. to the area of orbit was 22 +4, 29 + 4,24 +3,14 +2 on section 2-5 respectively . The ratio of the total thickness of the horizontal m. to the corresponding width of orbit was 37 +5,40+7,35 +4,26 +3 on section 2 - 5 respectively. Conclusion: The two ratios in section 3 can be employed to evaluate the developing likelihood of optic neuropathy in Graves' Ophthalmopathy.
