Relationship between central corneal thickness and retinal nerve fiber layer thickness in ocular hypertensive patients 高眼压患者角膜中央厚度与视神经纤维层厚度之间的关系
Results: The improvement of corneal pellucidit is in evidence and the area of supplying corneal layer has a little macula and nebula only after operation. 对角膜白斑、斑翳、云翳均有效,无明显差异;结果:7只兔术后瞳孔区透明度均明显改善,供角膜区少量云翳。
Results There were corneal epithelial apoptosis after LASEK, particularly in the based epithelial layer. 结果在所有行准分子激光角膜上皮下磨镶术的患者角膜上皮均见有凋亡细胞,以基底细胞层多见。
Conclusion After PRK, corneal epithelium cells and Bowman's layer were removed and fibroblasts were actived to produce new collagen. Most anterior stroma showed irregular lamellar structures with an increased number of fibroblasts which induce haze. 结论PRK去除了角膜上皮及前弹力层,术后上皮及浅基质层细胞增生明显,成纤维细胞活化增殖,新生胶原排列不规则,是导致角膜透明度下降的原因。
Results: The expression of iNOS mainly located into the inflammatory cells in corneal stroma layer and endothelial cells of neovascularization. 结果:碱烧伤后大鼠角膜上诱导型一氧化氮合成酶主要表达于基质层中浸润的炎性细胞和新生血管内皮细胞。
Reconstruct Rabbit Corneal Epithelium in vitro with a Free-feeding Layer Culture System and Autograft 家兔角膜上皮植片无饲养层构建与自体移植
Conclusion The migration of corneal epithelial stem cells in the human fetuses was from the whole layers to basal layer and confined to limbus region finally, and their ultrastructure was immature. 结论胎儿角膜上皮干细胞呈现由全层向基底层,再向缘部逐渐迁移的分布规律,且超微结构较幼稚。
Conclusion the reconstructed rabbit corneal epithelium hi vitro with a free-feeding layer culture system could be autografted to repair total corneal limbal stem cells deficiency. 结论采用无饲养层细胞培养体系构建自体角膜上皮组织,移植后可以成功修复角膜缘干细胞缺失的角膜上皮。
The corneal epithelium has good proliferating ability under normal conditions, because of existing corneal stem cells in the corneal limbus basal layer, the corneal stem cells are the origin for corneal epithelial proliferation and differentiation. 正常情况下角膜上皮具有很强的再生能力,这和角膜缘上皮基底层存在着角膜干细胞有关,角膜干细胞是角膜上皮细胞增殖和分化的源泉。
Histopathologic and Ultrastructure Changes of Corneal Dystrophy of Bowman Layer, Type I I型角膜前弹力层营养不良的组织病理学与超微结构研究
Culture corneal limbal cells on amnion membrane by cell-suspension method could obtain plentiful cells and the cellular layer was better for transplantation. 因此,以羊膜为载体悬浮细胞培养法较组织块法可以在体外获得大量均匀连续、性质单一角膜缘上皮细胞,并且传代后的细胞具有较高的增殖能力。
Methods: Using needle sensor digital thermometer to determine the variation of the temperature in the anterior chamber, corneal deep layer and the incision on the limbus of pig eye underwent Er: YAG lens photolysis in vitro. 方法:使用针式传感器数字型温度计,测量Er:YAG激光乳化晶体过程中离体猪眼球前房、角膜深层及角膜缘切口三部位组织温度。
Purpose: To explore the histopathologic and ultrastructure changes of corneal dystrophies of bowman layer, type ⅰ ( CDB ⅰ) in Chinese. 目的:探讨Ⅰ型角膜前弹力层营养不良(cornealdystrophyofBowmanlayer,CDBI)的组织病理学和超微结构改变。
The corneal endothelial cells form a boundary layer between anterior chamber and cornea. 角膜内皮细胞作为单层细胞在前房和角膜之间形成一层边界。
Injuries of the corneal endothelial layer in humans lead to corneal swelling and translucence. 角膜内皮细胞的损伤会导致角膜的水肿和混浊。
Epi-K epithelial knife detach a complete corneal flap, there is neither residual epithelial cells, it will not damage before the elastic layer, but will not damage the substrate layer, can be retained to prepare a smooth surface for excimer laser ablation. Epi-K角膜上皮刀可分离出完整的角膜上皮瓣,既不会有上皮细胞残留,也不会损伤前弹力层,更不会损伤基质层,可以保留光滑的平面以备准分子激光切削。
