眼眶

The most common cytologic forms of malignant lymphoma involving the orbit are the histiocytic and lymphocytic types.

累及眼眶的恶性淋巴瘤的最常见的细胞学类型是组织细胞和淋巴细胞型。

No blood flow signal was obtained in 12 cases with dermoid and 8 cases with lymphangioma.

目的 探讨彩色多普勒超声技术在儿童眼眶肿瘤诊断中的临床价值。

Objective To compare and analyze the modern photographic methods used for locatization and analysis of the nature of orbital dermoid cysts.

目的：比较分析影像检查方法对眼眶皮样囊肿的定位及定性诊断的价值。

Results among 34 cases of orbital tumor,29 cases were with benign tumor, 5 cases of malignant tumor, 8 cases of hemangioma,5 cases of dermoid,5 cases of inflammatory pseudotumor,3 cases of liparomphalus,3 cases of haematoma,3 cases of mixed tumor of lacrimal gland,2 cases of optic nerve glioma, 2 cases of cancerometastasis,2 cases of adenocarcinoma,1 cases of malignant lymphoma.

结果 34例眼眶肿块患者中，良性肿块29例，恶性肿瘤5例；其中血管瘤8例，皮样囊肿5例，炎性假瘤5例，脂肪瘤3例，泪腺混合瘤3例，血肿3例，视神经胶质瘤2例，腺癌2例，转移性癌2例，恶性淋巴瘤1例。

Objective To studay the best time and method of reconstruction of orbit and enophthalmos,and the influence on visual fuction.

目的：研究眼眶骨折眼球内陷手术复位的方法和手术最佳时期，探讨手术前后视功能变化。

Methods 100 cases with enophthalmos and orbital fracture were operated, and examinated by using the computed tomography, flash electroretinogram and pattern visual evoked potentials before and after operation.

应用螺旋CT影像和视觉电生理检查技术对100例施行眼眶重建和眼球复位手术的患者进行观察研究。

The orbital fracture may lead to many serious consequences including diplopia, enophthalmos and disturbance of ocular movement.

讨论：眼眶骨折可导致一系列并发症，包括眼球内陷、复视和眼球运动障碍，复视和眼球运动障碍与骨折移位和眼外肌嵌顿有关，骨折复位、解除嵌顿多可得到治疗，而眼球内陷的治疗则较为困难。

Methods 96 cases were devied into early stage group (60 cases, within three weeks )and later period group(36 cases, over three weeks).In early stage group, the time and degree of enophthalmos were observed. In later period group, the orbital volume behind the axis of the globe and degree of the enophthalmos were measured. The relation between the changes of orbital volume behind the axis of the globe and the degree of the enophthalmos was assessed by using Pearson correlation coefficients.

将96例患者按发病时间分为早期病例组（60例、受伤时间1周以内）和晚期病例组（36例、受伤时间3个月以上），早期组除进行后部眼眶容积测量外，分别于1周、2周、3周测定眼球突出度（相差＞1mm为阳性），记录眼球内陷出现时间，用卡方检验进行统计学分析；晚期组测量后部眶容积增大值和眼球内陷量，对其相关性采用Pearson统计方法进行统计学分析，并得出回归方程及相关系数。

The research cases are the patients with single lateral orbital fracture accepted treatment in the trauma center of Peking university school and hospital of stomatology during 2004.9 to 2007.3. All patients accepted ophthalmological examination including the degree of enophthalmos, the degree of diplopia and eyesight.

材料和方法：2004年9月～2007年3月在北大口腔医学院接受治疗的眼眶骨折患者，所有患者在手术前后常规行CT平扫（层厚0.625mm），并行眼科检查，包括：眼球突度、视力、复视、眼球运动等。

METHODS:Forty cases of traumatic optic neuropathy were analyzed retrospectively. Univariate analysis (Chi-square test) and logistic regression were performed to filter the risk factors to the visual prognosis of traumatic optic neuropathy. Eight variables were tested, including corticosteriod treatment in 2 days after trauma,no light perception,frontal or temple trauma,orbital hemorrhage and/or fracture,disturbance of consciousness,age ,other ocular trauma and presence of blood within the sphenoidal or ethmoidal sinus.

回顾分析40例外伤性视神经病变患者的临床资料，将伤后2d内是否接受激素治疗，伤后有无光感，有无意识障碍，是否有额颞部受伤，有无眶内积血和或眼眶骨折，患者年龄，是否合并其它眼外伤及是否有蝶、筛窦积血等8个变量纳入研究，通过单因素分析（χ 2检验）和多因素分析（Logistic回归分析），筛选出影响外伤性视神经病变视力预后的危险因素。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
