ObjectiveTo explore the association between age-related macular degeneration (AMD) and arthritis in a representative sample of the US population.DesignPopulation-based, cross-sectional study.SettingThe National Health and Nutrition Examination Survey (NHANES) 2005–2008.ParticipantsA total of 4813 participants aged 40 years and older with available information on AMD and arthritis in the 2005–2008 NHANES.MethodsThe status and types of arthritis were obtained from questionnaires. Non-mydriatic fundus photographs were collected. The types of AMD were assessed using the modified Wisconsin Age-Related Maculopathy Grading Classification Scheme. The association between arthritis and AMD was evaluated using logistic regression models.ResultsAfter adjusting for covariates, participants with any or early AMD had significantly lower odds of having any type of arthritis (any AMD: OR=0.56, 95% CI: 0.36–0.86; early AMD: OR=0.55, 95% CI: 0.34–0.88) or osteoarthritis (OA) (any AMD: OR=0.43, 95% CI: 0.26–0.71; early AMD: OR=0.44, 95% CI: 0.25–0.76) compared with those without AMD. When considering AMD as the outcome, significant negative associations were also found between any arthritis or OA and any (any arthritis: OR=0.64, 95% CI: 0.43–0.94; OA: OR=0.52, 95% CI: 0.33–0.82) or early AMD (any arthritis: OR=0.61, 95% CI: 0.40–0.93; OA: OR=0.51, 95% CI: 0.31–0.86) in the multivariable logistic models. There was no significant association between different types of arthritis and late AMD.ConclusionsPeople with arthritis, especially those with OA, were less likely to have AMD compared with those without arthritis and vice versa. Further studies are needed to confirm this potential protective effect of arthritis and/or arthritis treatment on AMD and to explore the underlying mechanisms.

ObjectiveTo determine the association between cataract surgery and age-related macular degeneration (AMD) in a representative US sample.DesignPopulation-based, cross-sectional study.SettingThe US National Health and Nutrition Examination Survey 2005–2008.ParticipantsA total of 5401 participants aged ≥40 years had information in cataract surgery status and gradable retinal photographs for right eyes.MethodsCataract surgery status was obtained from questionnaire. Non-mydriatic fundus photographs were collected and AMD status was assessed. The associations between AMD and cataract surgery were evaluated in right eyes using logistic regression models.ResultsOf 338 right eyes with any AMD, 107 right eyes (28.9%) had cataract surgery. After adjusting for multiple variables, there were significant associations between cataract surgery and any AMD (OR 1.36; 95% CI 1.03 to 1.81) or late AMD (OR 2.48; 95% CI 1.01 to 6.09). No significant association was found between cataract surgery and early AMD after adjusting for multiple covariates (OR 1.20; 95% CI 0.91 to 1.59).ConclusionOur results suggest that cataract surgery is associated with the presence of AMD, particularly for late AMD. Longitudinal studies investigating the risk and progression of AMD after cataract surgery are needed in the era of phacoemulsification.
