Three-dimensional imaging of lamina cribrosa defects in glaucoma using swept-source optical coherence tomography.
PURPOSE To visualize lamina cribrosa defects using three-dimensional (3D) swept-source optical coherence tomography (SS-OCT), and to determine the factors associated with this feature. METHODS All subjects were examined using an SS-OCT prototype system, which uses a tunable laser as a light source, operated at 100,000 Hz A-scan repetition rate in the 1050-nm wavelength. A 3D raster scan proto...
متن کامل3D Evaluation of the Lamina Cribrosa with Swept-Source Optical Coherence Tomography in Normal Tension Glaucoma
PURPOSE Although the lamina cribrosa (LC) is the primary site of axonal damage in glaucoma, adequate methods to image and measure it are currently lacking. Here, we describe a noninvasive, in vivo method of evaluating the LC, based on swept-source optical coherence tomography (SS-OCT), and determine this method's ability to quantify LC thickness. METHODS This study comprised 54 eyes, includin...
متن کاملPositional and Curvature Difference of Lamina Cribrosa According to the Baseline Intraocular Pressure in Primary Open-Angle Glaucoma: A Swept-Source Optical Coherence Tomography (SS-OCT) Study
PURPOSE To investigate the variation of lamina cribrosa (LC) structure based on the baseline intraocular pressure (IOP) in eyes with primary open-angle glaucoma (POAG) and healthy individuals using swept-source optical coherence tomography. METHODS A total of 108 eyes with POAG and 61 healthy eyes were recruited. Based on the baseline IOP, the POAG eyes were divided into higher-baseline IOP (...
متن کاملImaging of the Lamina Cribrosa using Swept-Source Optical Coherence Tomography.
The lamina cribrosa (LC) is the presumed site of axonal injury in glaucoma. Its deformation has been suggested to contribute to optic neuropathy by impeding axoplasmic flow within the optic nerve fibers, leading to apoptosis of retinal ganglion cells. To visualize the LC in vivo, optical coherence tomography (OCT) has been applied. Spectral domain (SD)-OCT, used in conjunction with recently int...
متن کامل[Enhanced Depth Imaging- optical coherence tomography technique and the lamina cribrosa in glaucoma].
The importance of the lamina cribosa in the pathogeny of glaucoma is well known, although exploration utilizing the “Enhanced Depth-Imaging” (EDI) technique with spectral domain optic coherence tomography (DS-OCT) is quite recent. Initially, it was used to assess and quantify choroidal thickness1–3 and now it has facilitated a quantum leap in qualitative, quantitative and dynamic in vivo examin...
