摘　　要：对１５例足月胎儿巩膜筛板的石蜡切片用计算机图像分析系统进行了形态测量学研究，发现足月胎儿巩膜筛板已形成区域性结构差异，即筛板上、下象限较鼻、颞象限筛孔大而结缔组织支撑成分较少，为青光眼性视神经损害发病机理的解释提供了新的理论依据。he computerized image analysis of cross sections at the scleral lamina cribrosa embedded in paraffin in the 15 cases of mature fetus was carried out.It was showed that there was a regional specificity in anatomy of the lamina cribrosa even in mature fetus,i.e.,less connective tissue support and larger pores in the superior and inferior qaudrants than in the nasal and temporal quadrants of the scleral lamina cribrosa. This result provided a new evidence for elaborating the mechanisms of the glaucomatous optic nerve demage.
