متن کاملPhotoprotection of human retinal pigment epithelium cells against blue light-induced apoptosis by melanin free radicals from Sepia officinalis.
Cultured retinal pigment epithelium (RPE) cells can phagocytize large foreign particles. Heterogeneous melanin aggregates from Sepia officinalis, a species of cuttlefish, were fed to cultured human RPE cells to produce cells laden with Sepia melanin. Blue light-induced apoptosis (BLIA) assays were performed by flow cytometry on parallel cultures consisting of RPE cells isolated from independent...
متن کاملNuclear Factor (Erythroid-Derived)-Related Factor 2-Associated Retinal Pigment Epithelial Cell Protection under Blue Light-Induced Oxidative Stress
Purpose. It is a matter of increasing concern that exposure to light-emitting diodes (LED), particularly blue light (BL), damages retinal cells. This study aimed to investigate the retinal pigment epithelium (RPE) damage caused by BL and to elucidate the role of nuclear factor (erythroid-derived)-related factor 2 (Nrf2) in the pathogenesis of BL-induced RPE damage. Methods. ARPE-19, a human RPE...
متن کاملLight-induced retinal changes observed with high-resolution autofluorescence imaging of the retinal pigment epithelium.
PURPOSE Autofluorescence fundus imaging using an adaptive optics scanning laser ophthalmoscope (AOSLO) allows for imaging of individual retinal pigment epithelial (RPE) cells in vivo. In this study, the potential of retinal damage was investigated by using radiant exposure levels that are 2 to 150 times those used for routine imaging. METHODS Macaque retinas were imaged in vivo with a fluores...
متن کاملBlue light-absorbing intraocular lens and retinal pigment epithelium protection in vitro.
PURPOSE To compare the Alcon AcrySof Natural (SN60AT) and AcrySof (SA60AT), the AMO Sensar (AR40e) and ClariFlex, and the Pfizer CeeOn Edge 911A intraocular lenses (IOLs) as to their ability to protect retinal pigment epithelial (RPE) cells from light damage mediated by the lipofuscin fluorophore A2E. SETTING Department of Ophthalmology, Columbia University, New York, New York, USA. METHODS...
