Smoking causes visual loss in elderly people
Age related macular degeneration is the most important cause of visual loss in elderly people, with smoking a major risk factor. Among patients aged over 75 taking part in a UK Medical Research Council trial in 49 general practices current smokers were found to have twice the risk of age related macular degeneration as non-smokers. The benefit of stopping smoking was seen after 10 years but equality with non-smokers took 20 years. The authors estimate that the condition is attributable to smoking in 28 000 elderly people in the UK. As sight cannot be restored in this condition, the finding is yet another reason to discourage smoking.
