Neurological manifestation of pre-eclampsia is not so rare. But isolated abducens nerve palsy in pre-eclampsia is very rare. We report a case of severe pre-eclampsia with isolated abducens nerve palsy.

40 patients who were diagnosed as the palsy of the third, fourth and sixth cranial nerve at Seoul national university hospital, were evaluated to reveal the etiology and clinical feature. The palsy of sixth cranial nerve is most common, and those of third and fourth cranial nerve followed it. Trauma was the most common cause of the palsy of the third, fourth, and sixth cranial nerve. Most of the palsy of the third cranial nerve involved both upper and lower branch, and aberrant regeneration was observed at 8 cases and its major cause was also trauma. The palsy of sixth cranial nerve was more frequently accompanied other cranial nerve palsy than those of the other two. Average recovery rate was 44.8% and, that of the sixth cranial nerve was higher than those of the other two.

Seventeen cases of paralytic strabismus secondary to abducens nerve palsy were treated with an injection of Botulinum Toxin A(Oculinum(R)) into the medial rectus muscle under the electromyographic control. All 17 cases, including 3 cases of bilateral abducens palsy, were followed up for 6 months to 23 months after the initial injection, there were no systemic side effects. The etiologic factors follow up deviation angle, dosage and complications were analyzed In the Thirteen cases of Oculinum(R) injection in antagonistic medial rectus muscle, the mean correction of preinjection deviation was 48.7%; the four cases who underwent both Jensen's operation and Oculinum(R) injection obtained 64.6%. The most common complication was ptosis which developed in 15 cases(64.7%) with a dosage of 2.75 u or above. From this study. we concluded that Oculinum(R) chemodenervation was effective in the acute case of abducens palsy without the anterior segment ischemia and systemic side effects.

PURPOSE: To evaluate the clinical features and natural course of sixth cranial nerve palsy. METHODS: We reviewed the medical records of 50 patients who were diagnosed with sixth nerve palsy from January 2000 to December 2006 to analyze the age of onset, etiology, recovery, and natural course of this disease. RESULTS: The mean age at onset was 43.2 years old. Vascular disease (n=17, 34.0%) was the most common cause of sixth cranial nerve palsy, followed by undetermined causes (n=14, 28.0%), trauma (n=10, 20.0%), and neoplasm (n=3, 6.0%). According to age group, vascular disease (n=7, 46.7%) was the most common cause in patients in their fifties and sixties, and trauma and undetermined causes (n=10, 76.9%) were the most common causes of this disease in patients in their twenties and thirties. Of the 40 patients who were followed up for more than 6 months, 28 (70.0%) showed improvement of paresis and 26 (65.0%) achieved complete recovery. The mean period to recovery was 3.7 months. No significant differences were observed in sex, age, laterality, and etiology between non-recovered and completely-recovered patients, but completely-recovered patients showed a significantly smaller initial angle of deviation than non-recovered patients. CONCLUSIONS: Vascular disease was the most common etiology of sixth nerve palsy. Sixty-five percent of patients showed spontaneous complete recovery, and completely-recovered patients showed a significantly smaller initial angle of deviation compared to that of non-recovered patients.
