摘要

Study of the structure of the lamina cribrosa is critical in glaucoma research. The purpose of this study is to determine the optimal spectral domain optical coherence tomography imaging protocol for the digital isolation and display of the lamina cribrosa. Three-dimensional datasets centered on the lamina cribrosa were obtained with 200 X 200 to 512 X 512 A-scan densities. The effect of scan density and c-mode slab thickness was subjectively compared. Increasing slab thickness reduced the sharpness of visible prelamina and lamina cribrosa structures. In retrolamina structures, thin slabs provided good visualization, but increased slab size increased the visibility of deeper structures. Scan times as short as 2.3 seconds (256 X 256 A-scans) degraded visualization of the shape of the optic nerve head. The optical scan protocol for lamina cribrosa imaging appears to be a 3 x 3 mm 200 X 200 A-scan volume with the lamina cribrosa positioned near direct current.
