N-Acetylcysteine Amide (NACA) Prevents Retinal Degeneration by Up-Regulating Reduced Glutathione Production and Reversing Lipid Peroxidation

“…Oxidative stress is believed to play a fundamental role in the pathogenesis of AMD and other retinal degenerations. 6,48,49 Patients with late AMD have been shown to have significantly lower antioxidant enzyme levels and higher lipid peroxidation by-product levels compared with patients with early AMD (P Ͻ 0.001 for each). 50 The role of oxidative stress in AMD has been further supported by several epidemiologic studies.…”

Ocular perfusion and age‐related macular degeneration

“…A recent study showed that primates raised on carotenoid‐depleted diets had a significantly increased incidence of angiographic transmission defects in the macular regions (Neuringer et al 1999). Previous studies have shown that a higher dietary intake of L and Z has been associated with a lower risk for AMD (Seddon et al 1994; West et al 1994). Another link between macular pigment and AMD derives from observations of atrophic AMD.…”

Mobile zinc as a modulator of sensory perception

“…A small but well‐controlled study published in 1988 found that adults who took twice‐daily zinc sulfate tablets experienced significantly less vision loss than those who were administered a placebo [ 142 ]. Given the uncertainty surrounding the small population sample size and relatively short duration of this study, a larger prospective investigation of the benefits and risks of zinc dietary supplementation was undertaken [ 143 ]. The results suggested a therapeutic benefit to taking either zinc, as zinc oxide, or a combination of zinc and antioxidants for patients at high risk of developing AMD [ 144 ].…”
