Durante un período medio de seguimiento de 6,5 años, murieron 534 (11%) de los 4753 participantes en el AREDS. Tras la corrección de los modelos, se observó que los participantes con DMAE sin o con escasas drusas tenían una mayor supervivencia. La DMAE avanzada se relacionaba con muertes cardiovasculares. Comparados con los participantes con una buena agudeza visual en ambos ojos, los que la tenían peor de 20/40, en un ojo, mostraban un mayor índice de mortalidad.
La opacidad nuclear y la operación de cataratas se asociaba con un incremento de mortalidad por cáncer y otras causas.
Los participantes a los que, de manera aleatoria, se les administró zinc presentaron menores tasas de mortalidad que los que no recibieron este suplemento.
