The presence of subretinal drusenoid deposits (SDDs) in patients with age-related macular degeneration (AMD) appears to be correlated with cardiovascular disease (CVD) and may serve as a useful tool for predicting certain forms of CVD. Here, we tested this hypothesis by examining whether patients with AMD with SDDs are more likely to have a cardiovascular-related condition and/or undergo a cardiovascular procedure. This is a retrospective cohort study. We included a total of 597 patients with AMD either with SDDs (n = 332) or without SDDs (n = 265). All patients underwent spectral-domain optical coherence tomography (SD-OCT). The SD-OCT scans were annotated by masked, experienced graders. We also extracted data from the patients’ electronic medical records (EMRs), including patient demographics, cardiovascular diagnoses, and CVD-related procedures based on ICD-9 codes. AMD patients with SDDs were more likely to be diagnosed with CVD or undergo a cardiovascular procedure compared to AMD patients without SDDs, particularly percutaneous transluminal coronary angioplasty (PTCA; OR 2.73, 95% CI [1.21, 6.13], p = 0.02). Multivariate analysis confirmed the association between the presence of SDDs and a background of PTCA in the presence of other covariates. These data suggest that the presence of SDDs in patients with AMD correlates with certain severe cardiovascular conditions; SDDs and CVD may share common pathogenic pathways.
