目的：采用角膜激光共焦显微镜观察研究颗粒状角膜营养不良家系患者的角膜状况。方法：采用角膜激光共焦显微镜对4例(6只眼)颗粒状角膜营养不良患者的角膜进行扫描检测，对比裂隙灯及普通显微镜观察分析检查情况。结果：颗粒状角膜营养不良患者的病变角膜裂隙灯下呈现面包屑样的灰白色混浊，在苏木精-伊红(hematoxylin-eosin，HE)染色中呈现出伊红染的颗粒，沉积于基质板层之间，在共焦显微镜下则为中高反光的团块，相互融合，并取代了基质细胞。结论：颗粒状角膜营养不良患者角膜病变从裂隙灯到普通HE染色下的显微镜，乃至高倍的共焦显微镜观察到的沉积物，分布情况相吻合，印证角膜病变发展的状况，有利于了解该病变的发展情况。
Objective: To observe and study the corneal in patients of family with granular corneal dystrophy by confocal laser scanning microscopy. Methods: The corneas of 4 patients (6 eyes) with granular corneal dystrophy were scanned by laser confocal microscopy, and the results were compared with those observed by slit lamp and ordinary microscope. Results: The image were gray and white bread-crumb-like opacity under the slit-lamp of cornea in patients of family with granular corneal dystrophy, were eosin-stained granules deposited between stroma layers in hematoxylin-eosin (HE) stain under the microscopy, were high reflective masses under the confocal laser scanning microscopy, which fused with each other. Conclusion: The image of the corneal in patients of family with granular corneal dystrophy were clearer and clearer by from Slit Lamp and microscopy to the confocal laser scanning microscopy. The distribution of sediments was consistent with each other. It can be a good understanding of the development of the disease.
