筛板是位于视旁深部，由胶原纤维构成的筛束和穿行有神经、血管及神经胶质细胞的筛孔组成的复杂结构，为视网膜神经节细胞轴突穿出眼球时提供结构和营养支持。眼压引起机械应力的直接作用以及筛板变形和重塑导致轴浆运输、血运障碍，共同导致视网膜神经节细胞轴突损伤进而死亡。因此，筛板被认为是青光眼病变的始发部位。光相干断层扫描技术的发展提高了对视旁深部结构的成像质量，目前视旁筛板的定量研究指标包括筛板深度、筛板曲率、筛板厚度、筛板前组织、筛孔、局灶性筛板缺损以及血流动力学等。提高对筛板结构的定性定量了解，探究筛板的结构特征，理解筛板生物力学和血流动力学在青光眼发病机制中的作用，有助于将大数据研究运用于临床青光眼的诊断和治疗。“,”The lamina cribrosa (LC) is a complicated collagenous meshwork of trabeculae and laminar pores contain capillaries, nerves and neurogliocytes, which provides structural and nutrient support to the retinal ganglion cell axons as they exit the eye. The intraocular pressure causes direct damage or deformation and remodeling of LC, leads to axoplaxmic transport and blood supply disturbance. The preponderance of evidence suggests that LC is the principal site of glaucomatous damage. The development of optic coherence tomography (OCT) technology has improved the imaging quality of deep structures of the optic nerve head and makes it possible to detect LC. The quantitative research indexes of LC structure include LC depth, laminar curvature, laminar thickness, prelaminar tissue, laminar pore, laminar defect and hemodynamics. To improve the understanding of LC structure, explore the characteristics of LC and understand the biomechanical and hemodynamic pathogenesis of glaucoma, which would be contribute to the application of big data research in the diagnosis and treatment of glaucoma.
