Mortality in patients treated with intravitreal bevacizumab for age-related macular degeneration

Background: The aim of this study is to analyze mortality in patients treated with bevacizumab for wet AMD. Methods: We conducted a retrospective case-control study between patients who received intravitreal injections of bevacizumab as the sole treatment for exudative AMD between September 2008 and October 2014 (n = 5385) and age and gender matched controls (n = 10,756). All individuals included in the study were reviewed for sociodemographic data and comorbidities. Survival analysis was performed using adjusted Cox regression, using relevant adjusted variables. Results: During follow-up (maximum: 73 months), 1063 (19.7%) individuals after bevacizumab died compared with 1298 (12.1%) in the control group (P <.001). After adjusted Cox survival regression, mortality differed significantly between the groups, Odds ratio = 1.69, (95% C. I. 1.54-1.84), P <.001. Conclusions: We found an increased long-term mortality in individuals with wet AMD treated with bevacizumab compared to a same age and gender group without wet AMD.
