MALONDIALDEHYDE LEVELS IN PATIENTS WITH AGE-RELATED MACULAR DEGENERATION: A Systematic Review and Meta-analysis

Background/Purpose: The role of blood malondialdehyde (MDA) in age-related macular degeneration (AMD), the leading cause of new blindness in industrialized countries, is still matter of debate. We performed a systematic review and meta-analysis of the published data on the MDA levels in AMD patients. Methods: PubMed, ISI Web of Sciences, and Scopus searches were performed according to MOOSE guidelines. Case–control studies were eligible for inclusion. Participants and controls were AMD patients and subjects without AMD, respectively. The main outcome measures were wet AMD and dry AMD. MDA level was the main exposure variable. Data were pooled using a random-effects model. Results: Twelve case–control studies were identified. A total of 634 AMD patients (mean age 66.7 years) and 656 controls without AMD (mean age 67.8 years) were evaluated. Extreme between-study heterogeneity was observed (I2 = 96.8%, P
