PURPOSE Topical nepafenac readily penetrates the cornea and is metabolized to amfenac, a potent cyclooxygenase (COX)-1 and COX-2 inhibitor. In this study, we tested the effect of topical nepafenac in three murine models of ocular neovascularization (NV). METHODS A masked trial was performed to compare the topical effects of vehicle with one of several(More)
PURPOSE Polyamine analogues inhibit tumor growth in vitro and in vivo, and oligoamines with a chain length of 10, 12, or 14 are particularly potent. This study was conducted to investigate the effect of the decamines CGC-11144 and CGC-11150 in a mouse model of choroidal neovascularization (CNV). METHODS Mice with laser-induced rupture of Bruch's membrane(More)
PURPOSE Oral administration of PKC412, a kinase inhibitor that blocks several isoforms of protein kinase C (PKC) and receptors for vascular endothelial growth factor (VEGF), platelet-derived growth factor, and stem cell factor, inhibits ocular neovascularization in a murine model. The purpose of this study was to determine whether sustained local delivery(More)
PURPOSE To evaluate the effect of vitrectomy on the concentration of vascular endothelial growth factor (VEGF) and the pharmacokinetics of intravitreally injected bevacizumab in the aqueous humor in cynomolgus macaques. METHODS Pars plana lensectomy and a standard three-port vitrectomy were performed in one eye each of six macaques. After a minimal(More)
PURPOSE Platelet-derived growth factor (PDGF) is an important stimulatory factor for proliferative retinopathies. Expression of PDGF-B in the retinas of transgenic mice (hemizygous rho/PDGF-B mice) results in rapid-onset retinal detachment caused by proliferation of glial cells, endothelial cells, and pericytes, whereas expression of PDGF-AA (homozygous(More)
PURPOSE Our aim was to compare the 1 year efficacy and safety results of intravitreal bevacizumab (IVB) in two prospective, consecutive groups of patients with macular edema (ME) following branch retinal vein occlusion (BRVO). PATIENTS AND METHODS Twenty-five eyes with ME after BRVO received one IVB injection (single-injection group) and 27 eyes received(More)
