PURPOSE To determine whether specific dietary and synthetic flavonoids can protect human retinal pigment epithelial (RPE) cells from oxidative-stress-induced death. METHODS The efficacy and potency were determined of a variety of dietary and synthetic flavonoids on the survival of human ARPE-19 cells and primary human RPE cells treated with either(More)
We recently characterized three FGF-binding proteins (FGF-BPs) which are soluble forms of the extracellular domains of the high affinity FGF receptors (Hanneken, A. M., W. Ying, N. Ling, and A. Baird. Proc. Natl. Acad. Sci. USA. 1994. 91:9170-9174). These proteins circulate in blood and have been proposed to modulate the biological activity of the FGF(More)
A long-standing yet controversial bioactivity attributed to polyphenols is their beneficial effects in vision. Although anecdotal case reports and in vitro research studies provide evidence for the visual benefits of anthocyanin-rich berries, rigorous clinical evidence of their benefits is still lacking. Recent in vitro studies demonstrate that anthocyanins(More)
PURPOSE Mounting evidence suggests that oxidative stress contributes to the pathogenesis of many ocular diseases, including glaucoma and diabetic retinopathy. No treatments are available to prevent the neuronal degeneration that occurs in these disorders. The purpose of this study was to determine whether flavonoids, natural products that are abundant in(More)
Four consecutive patients with carotid-cavernous sinus fistulas that could not be treated by the standard techniques of endoarterial balloon occlusion or embolization were successfully treated by advancement of a detachable balloon catheter through the ipsilateral superior ophthalmic vein. Under angiographic monitoring, the balloon was passed into the(More)
Basic fibroblast growth factor (FGF) is a potent endothelial cell mitogen that has been proposed to play a role in proliferative diabetic retinopathy and other neovascular processes. Our understanding of the in vivo role of basic FGF in the pathogenesis of these disorders is limited. We studied the immunolocalization of basic FGF in 16 clinical cases of(More)
OBJECTIVE The authors performed a study to determine the effectiveness and safety of silicone oil as a substitute for gas to fill the vitreous cavity to treat macular holes. DESIGN Multicenter, nonrandomized, interventional trial. PARTICIPANTS Thirty-seven consecutive patients chose vitrectomy with silicone tamponade instead of gas to treat 40 eyes with(More)
PURPOSE Eriodictyol, a flavonoid found in citrus fruits, is among the most potent compounds reported to protect human RPE cells from oxidative stress-induced cell death. The present study sought to determine whether eriodictyol-induced phase 2 protein expression further enhances the resistance of human ARPE-19 cells to oxidative stress. METHODS The(More)
Retinal ischemia is a common cause of visual impairment and blindness. However, despite the significant advances that have been made in understanding the pathophysiology of retinal ischemia, effective treatments are still lacking. The goal of these studies was to use an in vitro model to identify molecules that could be neuroprotective for retinal ganglion(More)
Rabbit and human corneas were mounted in a specular microscope and perfused with a balanced salt solution of varying osmolality (200 to 500 mOsm). Measurements of corneal thickness were made throughout the perfusion period, and at selected times the corneas were fixed and prepared for scanning and transmission electron microscopy. A hypo-osmotic perfusion(More)
