  • Ocular manifestation of multiple sclerosis and neuromyelitis optica

      Objective To observe the ocular manifestations and therapeutic effect of multiple sclerosis (MS) and neuromyelitis optica (NMO) with ocular symptoms.Methods The clinical data of 107 patients who was diagnosed with MS and NMO with ocular symptoms in our hospital were retrospectively analyzed, including 81 MS patients and 26 NMO patients.The counting of erythocytes and leukocyte,protein content and oligoclonal bands were detected by MRI and cerebrospinal fluid (CSF) in order to ensure the clinical diagnosis with MS and NMO. All the patients had undergone regular ophthalmologic examination of visual acuity,slit lamp microscope and fundus examination.In addition,visual field and visual evoked potential (VEP) examination were performed to analyze the clinical characteristics of ocular manifestations.The patients were received therapy with large dose methylprednisolone or activating blood and dissolving stasis and trophic nerve by chinese medicine. The effects of three methods on ocular manifestations were analyzed. All the patients were followed up for one month to five years. Results Among 81 MS patients,retrobulbar neuritis occurred in 24 patients (29.6%), the other common symptoms included paralytic strabismus and diplopia(30.3%). Among 26 NMO patients,acute papillitis occurred in 12(46.2%),while retrobulbar neuritis occurred in 14 (53.8%). The most common symptom of both MS and NMO was impaired vision and high abnormal rate. The results of MRI showed that demyelinating lesions beside ventricle was the most performance in MS patients,while abnormalities in spinal cord were found in NMO patients.The results of CSF showed that the positive oligoclonal bands was 75.3% and 19.2% in MS and NMO patients respectively. The potential time delay and (or) amplitude declination were observed by VEP. Large dose methylprednisolone can improve vision and diplopia in a short period.Conclusion The abnormal ocular manifestations of MS and NMO patients are common and complicated. Ocular symptoms has important reference value in the early diagnosis of MS and NMO.

  • Concentration of endothelin-1 of plasma in patients with nonarteritic anterior ischemic optic neuropathy

    ObjectiveTo observe the concentration of plasma endothelin (ET-1) in patients with nonarteritic anterior ischemic optic neuropathy(NAION) and investigate the relationship between ET-1 and NAION.MethodsThe plasma levels of ET-1 in 41 patients with NAION and 15 age-matched normal control subjects were measured by radioimmuoassay (RIA). The patients with NAION were divided into high papilloedema group, light papilloedema group, and recovery group according to the degree of papilloedema; and were divided into group1 (within 14 days), 2 (within 15-30 days), 3 (within 31-60 days), and 4 (within 61-180 days) according to the disease course. The plasma levels of ET-1 in different groups were detected and compared.ResultsThe plasma level of ET-1 in patients with NAION was significantly higher than that in the normal subjects (t=5.02,P<0.05)and there was no obvious difference in NAION patients with different genders.There were significant differences of the plasma level among the groups with different degree of papilloedema(F=4.65,P<0.05). ET-1 plasma level gradually decreased as the disease course increased, and there were significant differences among the groups with different disease course(F=4.29,P<0.05). The difference of plasma level of ET-1 between Group 13 with corresponding disease courses and the control group was significant respectively(t1=5.92,t2=3.47,t3=2.18, P1lt;0.01, P2lt;0.05, P3lt;0.05)ConclusionThe plasma level of ET-1 in patients with NAION may be related to the degree of papilloedema lesion and disease courses.

  • 非动脉炎性前部缺血性视神经病变发病相关因素及治疗

    非动脉炎性前部缺血性视神经病变(nonarteritic anterior ischemic optic neuropathy,NAION)是一种多因素性眼病,与众多全身和局部因素有关。全身因素中,高血压,夜间低血压,糖尿病,失血,血流变性异常等较为常见;眼局部因素主要与视盘解剖特征,眼压和屈光状态有关。在全身和局部各种因素共同作用下,睫状后动脉病变导致视盘和部分筛板后视神经缺血性损害是其发病的基础。尽可能针对各种相关因素以预防其发生和减轻病变程度至关重要,视不同情况可分别使用全身皮质类固醇,左旋多巴与卡比多巴,阿斯匹林,血液透析,高压氧,视神经鞘减压术等进一步治疗。 (中华眼底病杂志,1999,15:125-127)
