2 115660_vitalux_detailaid.qxd 21/04/04 15:56 Side 2 The retinal oxidative stress cascade Triggers * Free radicals What is oxidative stress? Free radicals initiate local molecular instability leading to cellular damage. Formation of free radicals is caused by: metabolism, sunlight (blue light spectrum), other free radicals, lack of antioxidants and other factors. Oxidative stress AMD/Diabetic Retinopathy 2 Visual deterioration * Age, Smoking, Poor diet, Excessive light exposure, Systemic diseases, Hereditary predisposition The retina is particularly vulnerable to oxidative stress. Contributing factors include 1 high consumption of oxygen a diet high in polyunsaturated fatty acids cumulative exposure to irradiation 1. Beatty et al.

Subjects had AMD and were categorized into four groups according to disease severity. Subjects were randomized to receive either antioxidants (Vit C 500 mg, Vit E 400 IU, and Beta Carotene 15 mg), zinc and copper (80 mg and 2 mg respectively), antioxidants plus zinc and copper, or placebo. Average follow-up was 6.3 years. 7 The AREDS treatment showed a beneficial effect in delaying the progression of intermediate AMD* to advanced AMD**.
