The Claim

Current cigarette smoking is associated with a 96% higher risk of developing neovascular age-related macular degeneration compared to non-smoking individuals, based on pooled case-control data, while cohort data show a weaker and non-significant association.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

People who currently smoke cigarettes have a 96% higher rate of developing neovascular age-related macular degeneration than people who do not smoke, according to case-control studies; cohort studies show a smaller and statistically insignificant link.

See the scientific wording

Current cigarette smoking is associated with a 96% higher risk of developing neovascular age-related macular degeneration compared to non-smokers, based on pooled case-control data, while cohort data show a weaker, non-significant association, indicating that study design and population selection influence the observed strength of this association.

Why this might work

Cigarette smoke chemicals enter the bloodstream and damage cells in the back of the eye, causing inflammation and stress that force new leaky blood vessels to grow where they shouldn't, leading to vision loss.

  1. Study: Smoking and the risk of age-related macular degeneration: a meta-analysis.

    Smokers are almost twice as likely to get a serious eye disease called wet AMD, especially according to studies that compare people who already have the disease to those who don’t. Long-term studies don’t show this as clearly, which means how you study it changes the result.
