PURPOSE Extracellular matrix (ECM) composition, tension, and rigidity modulate cell-ECM interactions and have substantial impact on cell functions. The authors studied the effects of ECM rigidity on human trabecular meshwork (HTM) cells to assess ECM rigidity as a possible pathophysiologic factor in glaucoma. METHODS Trabecular meshwork cells derived from(More)
PURPOSE Riboflavin/ultraviolet A (UVA) cross-linking (CXL) of corneal collagen is a novel method of stabilizing corneal mechanical properties and preventing progression of keratectasias. This study was conducted to investigate whether CXL influences ablation rate, flap thickness, and refractive results of excimer laser procedures ex vivo. METHODS Corneal(More)
Transfer of cDNA to corneal endothelial cells has been demonstrated in cell monolayers in vitro, in endothelium of whole thickness corneas ex vivo and following intracameral injection. Studies examining the feasibility and optimal methods for gene transfer to the cornea have used viral and non-viral vectors, initially histochemical or fluorescent marker(More)
In response to bacterial infection epithelial cells up-regulate expression and secretion of proinflammatory cytokines. Previous work from our laboratory showed that basolateral infection of polarized T84 cells with Yersinia enterocolitica induces interleukin-8 (IL-8) secretion in the absence of significant invasion. Here we studied Y. enterocolitica-induced(More)
Dear Editor, In their article, Søndergaard et al.1 concluded that the riboflavin during CXL treatment is only enriched in the anterior cornea. These results are in conflict with other measurements. Riboflavin fulfills two inseparable functions in the collagen cross-linking treatment (CXL). First, it serves as a photosensitizer of the photochemical(More)
Yersinia enterocolitica infection of epithelial cells results in interleukin-8 (IL-8) mRNA expression. Herein we demonstrate that besides IL-8, increased mRNA levels of five other cytokines, IL-1alpha, IL-1beta, monocyte chemoattractant protein 1 (MCP-1), granulocyte-macrophage colony-stimulating factor (GM-CSF), and tumor necrosis factor alpha (TNF-alpha),(More)
Primary open-angle glaucoma (POAG) is a leading cause of blindness due to chronic degeneration of retinal ganglion cells and their optic nerve axons. It is associated with disturbed regulation of intraocular pressure, elevated intraocular levels of TGF-β2, aberrant extracellular matrix (ECM) deposition and increased outflow resistance in the trabecular(More)
BACKGROUND Photochemical collagen cross-linking with riboflavin and UV-A radiation (CXL) is reported to strengthen the cornea in keratoconus. This retrospective longitudinal study analyses the outcomes 2 years after CXL. METHODS 46 eyes of 45 patients with keratoconus stadium 1 to 3 with disease progression confirmed by topography or patient history(More)
Background: To present a case of conjunctival lymphangioma in a 4-year-old girl with tuberous sclerosis complex. Methods/results: A 4-year-old girl presented with a relapsing cystic lesion of the bulbar conjunctiva in the right eye with string-of-pearl-like dilation of lymphatic vessels and right-sided facial swelling with mild pain. Best-corrected vision(More)
