Intracranial aneurysm is one of the major causes in cerebral hemorrhage and subarachnoid hemorrhage. About 20% patients with intracranial aneurysms have clinical symptoms or signs of eye in early stage. One of them is acute monocular mydriasis without other signs. Sometimes the patients would receive timely treatment and be saved if ophthalmologists can recognize this sign. This editorial reviewed some physiological and pathological factors resulting in acute mydriasis from the point of anatomy, etiology and diagnosis , and emphasized the relation and clinical significance between intracranial aneurysms and monocular mydriasis.

Optic neuritis and multiple sclerosis are common diseases of neuro-ophthalmolgy.It is concord for doctors in the recognition,diagnosis and therapy of optic neuritis abroad.But there is much debate on the concept,diagnosis and therapy in optic neu- ritis and multiple sclerosis in China.It is the responsibility of ophthalmologists to have correct cognition in the concept and diagnosis on optic neuritis and multiple sclerosis,and to save visual function of patients through reasonable normative therapy.Active exploration and necessary disputing are beneficial to recognize this disease,and important to obtain the best therapy program,too.(Ophthalmol CHN,2007,16:361-362,364)

Neuro-ophthalmology is a subspecialty of both neurology and ophthalmology concerning visual problems that are related to the nervous system. As the rapid development of computer technology, information technology and radiology, the development of neuro-ophthalmology is in the best period in history. The following important topics are worthy of attention: 1) the diagnosis and therapy of carotid artery stenosis related ophthalmopathy;2)the relationship between papilledema and cranial venous sinus thrombosis; 3) the diagnosis of optic canal fracture with high resolution computer tomography;4)the relationship between optic neuritis and multiple sclerosis.

Neuro-ophthalmological emergencies are some ocular manifestations, which are associated with the sight or life-threatening diseases if not promptly treated, including acute visual loss, sudden diplopia or anisocoria.Some severe nerve system or orbitocranial inflammatory diseases frequently present neuro-ophthalmological symptoms at the early stage.Acute visual loss is the common complaint of optic neuritis, arteritic anterior ischemic optic neuropathy, rhino-orbital-cerebral mucormycosis, and pituitary apoplexy.Diplopia usually occurs in cavernous sinus thrombosis or intracranial aneurysm because of cranial nerve palsies.Additionally, intracranial aneurysms and carotid artery dissecting aneurysm often present anisocoria initially.The clinical symptoms, signs, diagnosis and management of these disorders were reviewed from the point of emergency medicine, and the role of neuro-ophthalmological signs in the diagnosis was highlighted in this review, aiming to help ophthalmologists improve the awareness of these conditions, and emphasize the urgency of these signs.

Neuromyelitis optica spectrum disorder (NMOSD) is a kind of demyelinating disease of central nervous system which mainly affect optic nerve and spinal cord. Because of its serious blindness and disability, how to effectively prevent relapse has become the focus of ophthalmologists. With the deep understanding of the pathogenesis and the progress of scientific and technological means, more and more monoclonal antibodies(mAb) continue to enter clinical trials. B cell surface antigen CD20 blocker, rituximab, has become a first-line drug for the treatment of NMOSD. CD19 blocker, inebilizumab, can reduce the recurrence and disability of NMOSD patients. The addition of interleukin 6 receptor blocker, satralizumab, and complement C5 inhibitor, eculizumab, reduce the recurrence. Some mAbs such as natalizumab and alemtuzumab may not be effective for the treatment of NMOSD. The expansion of mAb treatment indications and the launch of new drugs still require more clinical trials which are large-scale and international cooperation. At the same time, its potential adverse events and cost issues cannot be ignored.

Background The research field of optic neuritis has developed rapidly and become more complex in recent years.It is very important for the reseachers and clinicians to known its status and the future trend.Objective This survey was to learn the distribution pattern,subject domain knowledge and worldwide research tendency of optic neuritis based on literatures in PubMed database.Methods Literatures on optic neuritis published in January 2000 to July 2012 were identified in PubMed database.The analytic dimention of an article included journal,published year,author,country and language.After core Mesh terms had been characterised by bibliographic item co-occurrence mining system (BICOMS),the co-occurrence matrix was built.Cluster analysis and multiple diamensional analysis were finished by SPSS 17.0.Then visualized network was drawn using ucinet 6.0.Results Totally 2 191 literatures were included,the number of articles increased from 105 in 2000 to 282 in 2011.The United States,England,Germany,Netherlands and Japan together accounted for 73.71％ of articles.There were 52 high-frequency subjects and hot topics were clustered into 9 categories.The visualized domain knowledge map was successfully built.The immunologic research was fully developed.The topic on etiology and diagnostic research,pathologic research,physiologic research and neuromyelitis optica (NMO) research had become core domain,while the studies of medication therapy,non-central nervous system idiopathetic demyelinating optic neuritis,epidemiology and genetics were not developed well.Conclusions Global optic neuritis publications display a continuous growth in the new millennium.The Big 5 in scientific literature on optic neuritis are the United States,England,Germany,Netherlands and Japan.The international main research focus includes 9 fields,which may provide reference or scholars both in scientific research and clinical research.

Optical coherence tomography (OCT) can depict mild papilledema and slight changes in the internal segment and external segment; measure thickness of the retinal nerve fiber layer,retinal thickness and macular volume; detect missing axons and damage to the macular ganglion cell complex.Thus,OCT has important application values and widespread prospects in diagnosis and differential diagnosis of glaucoma and non-glaucoma optic neuropathy,optic nerve diseases and macular diseases,outer and inner retinopathy as well as evaluation of curative effects,follow-up observation,prognosis and mechanisms in neuroophthalmological diseases.Neuro-ophthalmologists should pay more attention to the exploration and application of OCT in the field of neuro-ophthalmology.

Saliva and samples containing saliva were regarded as a kind of potential biological trace evidencefor individual identification in forensic science practice. In this paper, the authors have studied theDNA analysis of saliva and saliva containing samples. The results demonstrated that DNA can be extracted from saliva and saliva-containing samples. RFLPs analysis by DNA fingerprinting and PCRbased typing can be performed according to the amount of DNA extracted from these samples.

Background Neuromyelitis optica,term of Devic's disease,is characterized by the symptoms of both optic neuritis and myelitis.In clinic,misdiagnosis rate of neuromyelitis is too high to ignore because of the unsynchronous exsist of both optic neuritis and myelitis.Objective This study aims to analyze the clinical characteristics of Devic's disease in order to reduce the misdiagnosis rate.Methods Thirty six patients diagnosed as Devic's disease in General Hospital of PLA from January 2000 through October 2008 were included in this study.The clinical data including sex,age,initial events,clinical signs of optic neuritis and myelitis,misdiagnosis status were analyzed.Results The 21 patients showed the initial events of eye and were diagnosed as neurititis.In all of the 36 patient,the ratio of the patients was from 30 to 50 years.The prevalence of atrophy of optical nerve within 1-3 months was 72.7% and that of above 3 months was 91.4% in these patients.The incidence rate was obviously increased in 1-3 months course group (χ~2=7.59,P=0.009) and ＞3 months course group(χ~2= 20.29,P＜0.001) in comparison with ＜1 month course group.Two patients without clinical signs were determined the diagnosis by visual evoked potential.In 22 patients received magnetic resonance imaging of spinal cord,the lesions of 14 patients located in cervical cord and that of 9 patients was in thoracic cord and only 1 patient in lumbar cord.Conclusion Devic's disease is more common in female patients with the age between 30-50 years.Most patients visit ophtalmologist firstly due to initial events of eye.Occurrence of optic atrophy is associated with disease course.MRI suggest that the lesions of spinal cord are often in cervical cord and thoracic cord.
