Objective:To investigate extraocular muscles(EOM) susceptibility to myasthenia gravis(MG). 目的探讨重症肌无力(MG)患者眼外肌易于受累的机制。
Materials and Results In 322 patients with MG, 18 cases had alternative involvement of extraocular muscle (EOM) (5 6%). 材料及结果322例MG患者出现18例眼外肌交替受累，占5.;6%25。
Four months after the decompression, no morbidity of the extraocular muscles or other complications ensued. 而在右侧则经皮下行筛房切除术来做内侧及眼窝底减压术；而左侧则经鼻腔以内视镜行减压术。
Results The incidence of extraocular extension of malignant uveal melanoma was 15%. 结果葡萄膜恶性黑色素瘤眼外蔓延的发生率为15%25。
The extraocular extension account for about 20% of retinoblastoma of the same period. 眼外蔓延的发生率约占同期视网膜母细胞瘤的20%25。
However, range of motion of the extraocular muscles were severely compromised in both cases postoperatively. 但二往患者之眼球运动在术后均显著受到影响。
