The oculomotor disorders due to mesencephalic pathology are very varied. Function of the third cranial nerve may be affected at the level of the nucleus, in the mesencephalic fascicular portion, interpeduncular fossa, pathway anterior to the posterior communicating artery, sinus cavernosus, sphenoid fissure and orbit. Paralysis of the common oculomotor nerve is the least common of these. Generally it is secondary to ischemic, or sometimes to hemorrhagic vascular pathology.
We present the case of a hypertensive woman with an oculomotor nerve syndrome associated with limitation of horizontal gaze of the contralateral eye and reactive head inclination due to a mesencephalic haematoma.
The three neuro-ophthalmological findings seen in our patient have rarely been described in the literature. We consider the clinical observation of this case and the study of the organization of the oculomotor nerve nucleus to be of interest for publication.
中脑病变所致的动眼神经障碍多种多样。第三脑神经的功能可能在核团水平、中脑束状部分、脚间窝、后交通动脉前方的通路、海绵窦、蝶窦和眼眶处受到影响。动眼神经总干麻痹是其中最不常见的。一般来说，它继发于缺血性，有时也继发于出血性血管病变。
我们报告一例患有动眼神经综合征的高血压女性病例，该综合征与对侧眼水平凝视受限及因中脑出血而出现的反应性头部倾斜有关。
我们患者中出现的这三种神经眼科表现很少在文献中被描述。我们认为该病例的临床观察以及对动眼神经核团组织结构的研究值得发表。
