Immunohistochemistry of Proteoglycans in Human Lamina Cribrosa
American Journal of Ophthalmology, 1991Proteoglycans are macromolecular components of connective tissue, which are believed to have an important role in the organization of other extracellular matrix components and in the hydration and rigidity of tissue. Using antibodies to the heparan sulfate-, dermatan sulfate-, and keratan sulfate-proteoglycans core proteins, we used indirect ...

The Lamina cribrosa of Ornithorhynchus (Monotremata, Mammalia)
Anatomy and Embryology, 1988A vestigial and transitory lamina cribrosa was found in nestling platypus (Ornithorhynchus anatinus). The heads of two nest-young (180 and 333 mm length), one subadult and one adult Ornithorhynchus were serially sectioned and studied with special reference to the development of the nasal region.

Axonal Transport Interruption and Anatomy at the Lamina Cribrosa
Archives of Ophthalmology, 1982Pressure-induced, focal axonal transport abnormalities were studied in 14 cat eyes by the examination of serial step-section tissue radioautogram. Although the patterns of the transport interruption at the lamina cribrosa varied from eye to eye, the temporal sectors of the nerve head were most often involved by this abnormality.

Elastosis of the Lamina Cribrosa in Pseudoexfoliation Syndrome with Glaucoma
Ophthalmology, 1995Pseudoexfoliation syndrome is characterized by the presence of glycoprotein fibers in ocular and extraocular tissues, and often is associated with glaucoma. Pseudoexfoliation material may be associated closely with elastic microfibrillar-associated glycoprotein as well as elastin.Four optic nerve heads of two patients with pseudoexfoliation syndrome ...

The Anatomy at the Lamina Cribrosa in the Normal Cat Eye
Archives of Ophthalmology, 1982In normal cat eyes, the mean cross-sectional area of the nerve fiber bundles is greater in the temporal than in the nasal lamina cribrosa. The area occupied by the interbundle trabeculae is less in the temporal sectors than in the nasal sectors of the nerve. The number and the shape of the laminar pores are similar in all nerve sectors.

Elastosis of the Lamina Cribrosa in Glaucomatous Optic Neuropathy
Experimental Eye Research, 1998The purpose of this study was to determine whether elastotic degeneration of the elastin component of the lamina cribrosa occurs in optic neuropathy associated with different types of glaucoma. Human optic nerve heads with primary open-angle, neovascular, chronic angle closure and pseudoexfoliation glaucoma, and with varying duration of disease were ...

Structural Proteins of the Neonatal and Adult Lamina Cribrosa
Archives of Ophthalmology, 1989Optic nerve heads from three premature infants and six adults were studied immunohistochemically to compare the extracellular proteins in the lamina cribrosa of young and old human eyes. In both age groups, antibodies to the basement membrane components laminin and collagen type IV were associated with blood vessels and laminar beam margins.

Cell Adhesion Glycoproteins in the Human Lamina Cribrosa
Japanese Journal of Ophthalmology, 2001The distribution of the cell adhesion glycoproteins, laminin, fibronectin, tenascin, vitronectin, thrombospondin, and entactin/nidogen, was examined in the human lamina cribrosa.Frozen sections of the optic nerve head from 7 normal human elderly donors were stained by immunohistochemistry.All six glycoproteins were detected in this tissue.

Histomorphometry of the porcine scleral lamina cribrosa surface
Veterinary Ophthalmology, 1998The lamina cribrosa surface of the pig was examined using trypsin digestion, scanning electron microscopy, and computerized image analysis. Six normal eyes from healthy pigs were studied. The total intralaminar scan area, total number of laminar pores, median individual laminar pore areas, median individual pore form factors, and mean pore density were
