Objective To investigate the clinical features, causes of blindness and diagnosis of Vogt Koyanagi Harada syndrome Methods The data of 157 patients with VKH syndrome were reviewed and analyzed Patients were carefully examined with slit lamp, ophthalmoscope, three mirror lens, fundus fluorescein angiography, indocyanine green angiography and HLA typing Results Headache was noted in 73 5% of these patients Simultaneous involvement of both eyes occurred in 80 8% of these patients Chroiditis,papilledema and edema of the retina adjacent to the optic nerve were noted in 100% of these patients in the posterior uveitis stage, whereas recurrent granulomatous anterior uveitis (98 4%),"sunset glow" fundus (95 8%) and Dalen Fuchs nodules (71 2%) were the common ocular findings in the recurrent anterior uveitis stage The common causes of blindness were papillitis, exudative retinal detachment and complicated cataract in the posterior uveitis stage, anterior uveal involvement stage and its recurrent stage Poliosis (36 3%) and alopecia (35 0%) were the most common extraocular findings Early irregular patches of fluorescence, followed by localized hyperfluorescent spots were the typical findings of FFA Dilation of choroidal vessels and leakage of ICG from the choroidal vessels were the common ICGA findings The prevalence of HLA DR4 and HLA DRw53 in patients (54 9% and 71 8% respectively) was significantly higher than that in controls (14 7% and 38 2% respectively) Conclusions VKH syndrome is characterized by chroiditis, papillitis or neuroretinitis in the posterior uveitis stage, followed by a generalized uveitis with a typical recurrent granulomatous anterior uveitis Extraocular findings and relevant examinations including FFA, ICGA and HLA typing are helpful to the diagnosis of VKH syndrome

目的探讨Vogt-Koyanagi-Harada综合征患者的临床特征、盲目原因及诊断等有关问题。方法对在1996年1月至2000年12月间就诊资料完整的157例VKH综合征患者进行回顾性分析，并对裂隙灯、眼底镜、三面镜、荧光素眼底血管造影(fundus fluorescein angiography，FFA)、吲哚青绿血管造影(indocyanine green angiography，ICGA)及人类白细胞抗原分型等检查结果进行分析。结果 VKH综合征最常见的前驱症状为头痛(102例，73.5%)，双眼同时患病118例(80.8%)；后葡萄膜炎期眼部主要表现为脉络膜炎、视乳头及附近视网膜水肿(100.0%)；前葡萄膜炎反复发作期眼部表现为复发性肉芽肿性前葡萄膜炎(128例，98.4%)、晚霞状眼底改变(95.8%)及Dalen-Fuchs结节(71.2%)；后葡萄膜炎期、前葡萄膜受累期及前葡萄膜炎反复发作期导致盲目的主要原因分别为视乳头炎、视网膜脱离及并发性白内障；毛发变白(36.3%)及脱发(35.0%)是最常见的眼外表现；炎症活动期FFA典型表现为斑驳状高荧光，ICGA发现脉络膜血管扩张、通透性增高等改变；VKH综合征患者HLA-DR4及HLA-DRw53的阳性率(54.9%及71.8%)显著高于正常对照组(14.7%及38.2%)。结论 VKH综合征患者在后葡萄膜炎期眼部典型表现为双侧脉络膜炎、视乳头炎或神经视网膜炎，随后出现以反复发作的肉芽肿性前葡萄膜炎为特征的全葡萄膜炎。眼外症状及相关的辅助检查包括FFA、ICGA 及HLA分型等有助于VKH综合征的诊断。

Results①The formation of posterior capsule opacification in rabbit eyes: observation in different stages after the operation showed the inflammatory response remarkable at the first three days with iris congestion; edge of anterior capsule circularity opacification at the 1st week, but no remarkable change in the posterior capsule; just gauze-like at the 2nd week; strip-like opacification at the end of the 1st month, funicular opacification after 2～3 months, while visible opacification at the 5th month after the operation.

结果：①兔眼后发性白内障形成情况：术后不同时期裂隙灯下观察可见术后前3d前房内炎症反应明显，虹膜充血；术后1周可见前囊截缘出现白色环状混浊，但后囊尚透明；术后2周后囊呈薄纱状；1个月出现线条状混浊，2～3个月成条索状混浊，术后5个月后囊明显混浊。

The results show that the karstification of marlite is influenced by many different factors. Joints and fissures are the most important factors. Different karst morphs come into being during the karst process, including twig-like, ring-shaped, radial pattern, beading-shaped, dispersed and biologic shell shaped ones.

结果表明：泥灰岩的溶蚀作用受不同因素的影响，特别是受节理裂隙发育的影响，形成多种不同的溶蚀形态，包括树枝状、环状及放射状、串珠状、分散状和生物壳状。

The gold orebody exists in phyllite, the second member of Gaixian Formation, Liaohe Group, lowerProterozoic Erathem, mainly in the form of vein, layer and lens, controlled by NNEschistosity belt and low order, secondary structure fissure.

金矿体主要以脉状、似层状、透镜状产于下元古界辽河群盖县组二段的千枚岩中，受北北东向片理化带及低序次构造裂隙所控制。

Results The tristar of groove was consisted of beak of the ethmoidal bulla and its prolonging process, apex of the uncinate process and anterior peak of the middle turbinate, at the region of frontal recess. The structures called meatal groove, uncinate groove and bullar groove were observed around the ethmoidal bulla and the tristar of groove located at their origination. Under endoscopic view these structures looked like a triangular clefts, so it was named.

结果 星状裂是由筛泡的顶端及其向上伸出的角、钩突的顶端、中鼻甲的前顶端在额隐窝区域汇合形成的一个星状裂隙，上述结构围绕筛泡形成鼻道沟、钩突沟、筛泡沟，星状裂为三条沟的起始部。

Furthermore, large-scale fold and fault structure hasn't been found around the Tianchi Lake, but the original prismatic joints and radial joints developed well in the trachyte, so the rock mass is dissected into fractured fragmental structure and the integration of rock mass is further destroyed.

在构造方面，长白山天池周围虽然没有发现大规模的褶皱断裂构造，但粗面岩中原生柱状节理、放射状节理十分发育，这些节理裂隙将岩体切割成十分破碎的碎裂结构，使岩体极易产生岩崩、落石，使岩体的完整性遭到了进一步的破坏。

According to the attitude, spacing and length of the joint cracks, t heir probability distribution was deduced.

根据实测的节理裂隙产状、间距及迹线长度，推断节理裂隙概率分布特征。
