The Claim
Cigarette smoking is independently associated with an increased risk of neovascular age-related macular degeneration after adjustment for age, comorbidities, and other potential confounders using propensity matching.
What the research says
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.
People who smoke cigarettes have a higher risk of developing neovascular age-related macular degeneration, a type of vision loss, even when accounting for other factors like age and existing health conditions.
See the scientific wording
The association between cigarette smoking and neovascular age-related macular degeneration persists after adjusting for age, comorbidities, and other potential confounders using propensity matching, suggesting that smoking is an independent risk factor for this form of blindness.
Cigarette smoke introduces toxic chemicals into the bloodstream, which damage cells in the eye and trigger persistent inflammation. This inflammation causes abnormal blood vessels to grow under the retina, leading to bleeding and vision loss.
What the research says
1 studyEven after accounting for age and other health problems, people who smoke are much more likely to develop a serious eye disease that can cause blindness — and the more they smoke, the higher the risk.
