Results MRI of all WE patients showed symmetrical high signals on the brain T2WI, Flair and diffusion weighted imaging, 6 cases of them in the medial thalamus, 4 cases in surrounding the aqueduct, 3 cases in the third ventricle gray matter, 2 cases in the mamillary bodies, 1 case in the putamen,1 case in the optic chiasm, 1 case in the superior cerebella vermis and 1 case in the subcortical white matter; 2 cases had reinforcement effect. 2 cases showed no abnormal signals on T2WI and Flair early, but showed high signal symmetrically in the medial thalamus on DWI imaging.

When chondroitinase ABC was given to degradate CSPGs in the developmental nervous system such as the optic chiasm, the projection and destination of growing axons were altered. Also in SCI, ChABC treatment in the injuryed sites can increase regenerating ability of axons and improve spinal cord rehabilitation.

以往对发育阶段的神经系统如视交叉部位给予软骨素酶ABC降解CSPGs后，可观察到生长轴突延伸方向和终止部位的改变；SCI后，受损处给予ChABC处理，轴突再生能力可增加，脊髓功能有所恢复。

Nonfunctioning adenomas are discovered incidentally or present with mass effect such as bitemporal hemianopsia with compression of the optic chiasm, headache with hydrocephalus, hypopituitarism, and cranial nerve palsies secondary to invasion of the cavernous sinus.

Oculocutaneous albinism type 4 (OCA4) is characterized by hypopigmentation of the skin and hair plus the characteristic ocular changes found in all other types of albinism, including nystagmus; reduced iris pigment with iris translucency; reduced retinal pigment with visualization of the choroidal blood vessels on ophthalmoscopic examination; foveal hypoplasia associated with reduction in visual acuity; and misrouting of the optic nerves at the chiasm associated with alternating strabismus, reduced stereoscopic vision, and an altered visual evoked potential.

疾病特征： 4型眼皮肤白化病（OCA4）的特点是皮肤和头发的色素减退以及所有白化病类型都有的典型的眼部改变，包括眼球震颤、虹膜色素减少而使其呈半透明状、视网膜色素减少而使得脉络膜血管在眼底镜检时可见、与中央凹发育不全导致的视敏度降低以及视神经交叉处路径错误引起的交替性斜视、立体感降低和视觉诱发电位改变。

Then the intracellular calcium concentration of neurons was measured by laser confocal scanning microscope , represented by the mean intracellular fluorescent intensity. On the ice, the cerebral cortical tissue at the infarction margin of the section after optic chiasm was rapidly dissociated about 100mg, then made into brain homogenate in low temperature. The high performance liquid chromatography was used to determine the Glu, Asp and Gly contents in homogenized brain tissue.

视交叉平面用2％TTC染色，用图像处理软件计算出脑梗死面积占该片脑组织面积的百分比；取视交叉前平面梗死边缘区皮层组织约100mg，用酶消化法制作神经细胞悬液，用激光扫描共聚焦显微镜检测皮层神经元细胞内游离钙离子浓渡，以细胞平均的荧光强度代表细胞内钙浓度；冰上迅速分离视交叉后梗死边缘区皮层组织约100mg，于低温下制作脑组织匀浆，用高效液相色谱法测定皮层匀浆中谷氨酸、天门冬氨酸、甘氨酸的含量。

The cerebral cortical tissue at the infarction margin of the section before optic chiasm was dissociated about 100mg and made into neuronal suspension by zymolysis.

于再灌注终点处死动物，冰上迅速取脑，冠状切为三部分：视交叉平面厚约2mm，视交叉前平面厚约2mm及视交叉后平面厚约4mm。

Moreover, we found that there was no direct relationship between visual problems and downward herniated optic chiasma in patients of empty sella syndrome.

此外吾等亦发现此类病患视觉上的问题与视径交叉之下凹无一直接的关係。

Results Among 38 cases of pituitary macroadenomas which had ivaded the surrounding tissue,5 cases showed the tumor growing upward simply and oppressing the optic chiasma,20 cases growing upward mainly and involving the sphenoid sadele,13 cases involving one or both sides of the sphenoid sadele mainly and ivading up or／and down.
