Morphometry of the human lamina cribrosa surface.
The lamina cribrosa is a sieve-like perforation in the posterior part of the sclera, that allows passage of the retinal ganglion cell axons and central retinal vessels and preserves a pressure gradient between the intraocular and extraocular space. It has been termed the primary site of glaucomatous damage to the optic nerve. Using electron microscopy, the authors morphometrically evaluated the...
متن کاملCell culture of the human lamina cribrosa.
The extracellular matrix of the lamina cribrosa may be important in the changes in the optic nerve head associated with glaucoma. To investigate the cell biology of this tissue, human lamina cribrosa was explanted in tissue culture and two cell types grown from this tissue were characterized. The most common cell type obtained was a large, flat, polygonal cell which was negative for glial fibri...
متن کاملAxon deviation in the human lamina cribrosa.
AIMS To examine the course taken by individual retinal ganglion cell axons through the human lamina cribrosa. METHODS Retinal ganglion cell axons were labelled using the retrograde tracer horseradish peroxidase applied directly to the optic nerve in two normal human eyes removed during the course of treatment for extraocular disease. RESULTS A majority of axons took a direct course through ...
متن کاملVariation of lamina cribrosa depth following trabeculectomy.
PURPOSE To investigate the long-term changes in lamina cribrosa (LC) depth following trabeculectomy. METHODS Serial horizontal B-scan images of the optic nerve head were obtained using spectral-domain optical coherence tomography from 28 primary open-angle glaucoma patients who underwent trabeculectomy and were followed up for at least 2 years. Approximately 65 B-scans covering the optic disc...
متن کاملHuman lamina cribrosa insertion and age.
PURPOSE To test the hypothesis that in healthy human eyes the lamina cribrosa (LC) insertion into the pia mater increases with age. METHODS The optic nerve heads (ONHs) of donor eyes fixed at either 5 or 50 mm Hg of IOP were sectioned, stained, and imaged under bright- and dark-field conditions. A 3-dimensional (3D) model of each ONH was reconstructed. From the 3D models we measured the area ...
