  • Descrição: Background: Results from several cohort studies have indicated that long-term low-dose aspirin (acetylsalicylic acid, ASA) use markedly increases the risk for neovascular age-related macular degeneration (nAMD). nAMD is a serious condition that causes rapid decline in central-field vision over the course of days to weeks. The studies currently available obtained data from questionnaires, therefore lacking high-quality information regarding exposure to low-dose ASA, and had few nAMD cases. Objectives: To quantify the risk for nAMD associated with long-term low-dose ASA use. Methods: A case-control study was conducted, including all cases of nAMD in the period 1 January 1987 - 31 December 2012 aged 50 years and older from the UK Clinical Practice Research Datalink (CPRD) database. Cases were matched to up to five controls on age, gender and general practice. Conditional logistic regression was used to estimate odds ratios for the risk of nAMD associated with increasing durations of low-dose ASA use, adjusting for smoking status, obesity, glaucoma, hypercholesterolaemia, and lipid lowering medication, and cardiovascular diseases. Results: 4,125 cases were matched to 20,173 controls. Cases had a median age of 80.1 years and were in majority female (64.7%). Overall, the risk for nAMD associated with low-dose ASA use was a small but significantly increased adjusted risk of 1.12 (95% confidence interval 1.03 - 1.21). We observed a trend for increasing risk with prolonged use: odds ratios were 1.06 (use for less than twoand- a-half years; 95% CI 0.96 - 1.17), 1.07 (twoand- a-half to five years; 95% CI 0.94 - 1.21), 1.17 (five to ten years; 95% CI 1.04 - 1.31), 1.23 (ten to fifteen years; 95% CI 1.05 - 1.45), and 1.33 (more than fifteen years; 95% CI 1.08 - 1.63), compared to no ASA use. Conclusions: Long-term use of low-dose ASA is associated with an increased risk for nAMD. This risk is lower than previously observed and small compared to other risk factors and the benefit-risk balance of low-dose ASA for the prevention of cardiovascular disease will not be impacted.
