Smokers risk sight loss, study claims

Smokers have a greater chance of losing their sight in later life, a new study has claimed.

Research published in the Royal College of Ophthalmologist’s journal Eye suggested that smoking “greatly increases” the chance of developing age-related macular degeneration (AMD), which leads to severe irreversible sight-loss.

The Royal National Institute of the Blind has called for the government to introduce warnings on cigarette packets, following the publication of the research.

A team of scientists, led by Simon Kelly, Consultant Ophthalmic Surgeon at the Bolton Eye Unit, reviewed 17 studies of the association between smoking and AMD. They found that smokers in 13 of the studies were significantly more likely to develop AMD than non-smokers.

Heavy smokers were at higher risk, the researchers claimed, and the risk was lower for ex-smokers – suggesting that the negative effects could at least be partly negated by quitting smoking.

AMD is the UK’s leading cause of sight loss, with around 500,000 suffering from the condition. An estimated 54,000 of those have the condition as a result of smoking.

However, according to a new report published by the AMD Alliance UK, only 7% of people know that AMD affects the eyes. However, seven out of ten smokers said that they would either stop smoking completely or reduce the amount they smoked, if they thought their eyesight could be affected.

Steve Winyard, RNIB’s Head of Campaigns and Chairman of AMD Alliance UK, called on the government to introduce specific warnings on cigarette packets and to fund a major public awareness campaign. He said: “Smoking is the only proven cause of AMD that people can do anything about, yet people are not aware of the link and most people have not even heard of the condition.”

Simon Kelly also supported calls for warnings on cigarette packets. He said: “Knowledge of the link between smoking and AMD is very low, but evidence from Australia and New Zealand shows that raising awareness of this link creates a powerful message for the general public.

“In my clinical experience when people are diagnosed with AMD and learn of the link with smoking they are often sufficiently shocked and motivated to want to stop smoking straight away.”
