Vitreous hemorrhage is the most frequent finding in ocular trauma. In cases with obscured fundus visualization associated pathologies (retinal tear, choroidal detachment, intraocular foreign body, retinal etc.) should be evaluated by ultrasonography and vitreous motility monitored even if retina attached. A decrease points to development of proliferative vitreoretinopathy requires early vitrect...

Staphylococcus aureus is an important cause of severe bacterial endophthalmitis. Both immunoglobulin (Ig) G and A antibody titers to ribitol teichoic acid (RTA), the major antigenic determinant of the S. aureus cell wall, were measured by an enzyme-linked immunosorbent assay in serum, tears, aqueous, and vitreous on days 3, 7, 10, 14, 21, and 30 after intravitreal injection of viable S. aureus ...

PURPOSE A new redox regulating enzyme, thioltransferase (TTase), has been found in the lens. The authors investigated whether TTase is also present in other ocular tissues. METHODS Fresh enucleated bovine eyes were obtained from a local abattoir 4 hours after death. The eyes were processed immediately to remove corneal epithelial cells, conjunctiva, corneal endothelial cells, iris, ciliary bo...

Purpose: The aim of our present work is the development of a quasi steady-state model for the distribution of intravitreally injected drugs and investigation of the effects of various model parameters on the drug distribution in normal and diseased eyes. Method: A simple mathematical model for the intravitreal transport of drugs was developed using Fick’s law of diffusion, Darcy’s law of convec...

The incorporation of U-^C-glucose into the nondialyzable polymers of the vitreous was studied both in vitro, xoith bovine tissue preparations, and in vivo, after the infusion of radioactive glucose through the lateral long ciliary artery of the cat. The radioactivity present in glucosamine isolated after Doioex 50 chromatography was taken as a measure of hyaluronic acid synthesis. It was found ...

recently, the use of stem cells has expanded into numerous areas including cell therapy. in this study, we investigated the differentiation capacity of human wharton’s jelly stem cells (hwjscs) into lens fiber cells. morphological changes and expressions of four crystallin genes (αa, αb, βb1 and βb3) were studied. the bovine vitreous body has been shown to induce expression of crystallin genes ...
