It has been known for many years that smoking triples to quadruples one's risk of getting AMD. Smokers also get AMD an average of 5 to 10 years earlier than non-smokers and are more likely to get the more aggressive wet form of the disease.
New research from a large, government-funded study in the USA also shows that people who commence injections for wet AMD, but continue to smoke, do not respond as well to treatment. Smokers were more than twice as likely to be legally blind by 5 years, compared to non-smokers receiving injections.
Most importantly however, smokers who give up when they start injections do almost as well as non-smokers.
So the message is clear. The earlier you give up smoking the better, but it is never too late to quit.
