PURPOSE To elucidate whether the gene polymorphisms of glutathione S-transferase (GST) M1, T1, and P1 are associated with the development of exudative age-related macular degeneration. METHODS The authors genotyped 35 white patients with exudative age-related macular degeneration and 159 healthy controls. Genomic DNA from peripheral blood was examined using polymerase chain reaction and defin...

Emerging treatments for dry age-related macular degeneration (AMD) and geographic atrophy focus on two strategies that target components involved in physiopathological pathways: prevention of photoreceptors and retinal pigment epithelium loss (neuroprotection induction, oxidative damage prevention, and visual cycle modification) and suppression of inflammation. Neuroprotective drugs, such as ci...

Macular pigment (MP) is a pre-receptoral filter that is diet derived and deposited in relatively high optical density in the foveal region of the retina. Due to its yellow coloration, MP absorbs light of relatively short wavelengths, ranging from 400 nm to 520 nm. Despite the spectral and spatial nonuniformity imposed upon the sensory retina by MP, perception appears to be relatively uniform ac...

This study presents a mouse model for human age-related macular degeneration (AMD) as characterized by subretinal deposit and choroidal neovascularization. Matrigel, a basement membrane extract, solidifies after implantation in tissue and can stimulate local angiogenesis. This study demonstrates the induction of neovascularization and focal retinal degeneration following subretinal Matrigel inj...

purpose: to evaluate the visual outcomes and complications of low power transpupillary thermotherapy (ttt) in patients with neovascular age-related macular degeneration (amd). methods: the study included 20 eyes of 17 patients. diagnosis of exudative amd was established on the basis of fundus examination and fluorescein angiography (fa). ttt was performed using a diode laser at 810 nm wavelengt...

OBJECTIVE To determine the effects of age and central vision loss on driving skills. METHODS Ten subjects with age-related macular degeneration and average binocular visual acuity of 20/70, and 11 age-similar subjects with normal vision, were examined with a battery of cognitive and visual tests, an interactive driving simulator, and an on-road driving test. Data were collected on the frequen...
