oculomotor nerve palsy

Purpose : To evaluate the value of MRI in diagnosis of the oculomotor nerve palsy.

目的: 探讨MRI诊断动眼神经麻痹的价值.

14 patients were with subarachnoid hemorrhage and 4 patients with oculomotor nerve palsy.

其中蛛网膜下腔出血（SAH）14例、动眼神经麻痹4例。

Two patients developed permanent oculomotor nerve palsy. Twelve patients developed temporary cranial nerve deficit.

术后2例患者出现永久性动眼神经瘫，12例出现暂时性颅神经损害。

Conclusions In atypical cases, the retraction of the globe in adduction was not obvious and the diagnosis of DRS must be differentiated from the following ocular motility disorders, namely, abducens nerve palsy, Mebius syndrome, congenital oculomotor apraxia and congenital or infantile esotropia.

结论非典型患者内转时，眼球后退不明显，诊断DRS时应与眼球运动异常疾病即外展神经麻痹、Moebius综合征、先天性眼球运动不能和先天性或婴儿型内斜视相鉴别。

Methods Digital subtraction angiography ( DSA) were performed in 41 patients with clustering TIA in the carotid artery supplying territory and in 25 patients with oculomotor nerve palsy as control.

方法采用数字减影血管造影（DSA）对41例频发TIA患者（TIA组）及25例单纯动眼神经麻痹患者（对照组）进行检查。

Result: There are 9 cases of oculomotor nerve palsy, 3 cases of abducens nerve palsy and 1 case of trochlear nerve palsy in the total 15 cases. The rest 1 case have both oculomotor and abducens nerve paralysis.

结果：15例患者均为单眼，单动眼神经麻痹9例，单外展神经麻痹3例，单滑车神经麻痹1例，动眼神经合并外展神经1例，15例患者瞳孔均正常。
