Retinal Microenvironment Imbalance in Dry Age-Related Macular Degeneration: A Mini-Review

Background: Age-related macular degeneration (AMD) is the leading cause of blindness in the western world. To prevent what will certainly be a tremendous health and economic burden, effective therapeutics for AMD are urgently needed. To develop these agents in a timely fashion, the molecular pathways that cause disease progression must be elucidated. Objective: To briefly describe the clinical features of AMD, and review the current understanding of the molecular basis of AMD. Methods: A literature review. Results: The discussion will primarily focus on the interplay of oxidative stress and complement dysregulation and the resulting chronic proinflammatory state thought to be central in AMD pathogenesis. Conclusions: Oxidative stress and complement dysregulation play a substantive role in the development of AMD.
