活体粘连虹膜在角膜激光共焦显微镜下表现及图像分类

The study of the human iris of synechiae by in vivo confocal microscopy and images classification

目的应用角膜激光共焦显微镜观察活体粘连虹膜的形态学特征。方法临床病例观察对比研究。对2008年3月至2011年3月在深圳市眼科医院应用共焦显微镜观察15例各种原因引起虹膜与角膜粘连的患者，进行角膜激光共焦显微镜检查，透过透明的角膜组织观察到了活体粘连虹膜组织的共焦显微镜图像，并对图像进行分类研究。结果角膜激光共焦显微镜下活体粘连虹膜的形态结构分为6种：（1）树干状支架结构。（2）树枝状支架结构。（3）树丛状支架结构；（4）结果状结构。（5）上皮样结构。（6）深层结构。结论角膜激光显微镜能够观察特定条件下的活体虹膜显微结构，特别能清晰观察虹膜表面的支架结构和色素团块结构，有助于对各种累及虹膜疾病的深入理解。

Objective To observe and analyze the morphologic characteristics of the human iris of synechiae by in vivo laser confocal microscopy. Methods fifteen eyes of 15 patients were exam- ined by in vivo confocal microscopy, and summarize the morphologic characteristics. Results There were six kinds of the human iris of synechiae images mainly by in vivo confocal microscopy,includ- ing： （ 1 ） trunk-like bracket structure ; （2） dendritic-like bracket structure ; （3） bush-like bracket structure; （4）fruitful-like bracket structure; （5）Epithelioid-like structure; （6）deep structure. Conclusions Laser confocal microscopy is a good tool for study the microstructure of the iris of synechiae under certain conditions , especially for bracket structure and pigment granule in it ,which can help us to study the disease about the iris deeply.
