Update the hemodynamic and vascular model of age-related macular degeneration (AMD) by integrating evidence on retinal pigment epithelium lipoprotein clearance and assessing the protective rationale for cardiovascular therapies.
Synthesized theoretical and experimental literature spanning four decades on vascular and hemodynamic drivers of AMD.
Evaluated physiological mechanisms involving retinal pigment epithelium (RPE) lipoprotein processing, Bruch's membrane alteration, and choriocapillaris perfusion.
Reviewed observational and clinical evidence evaluating the protective effects of statins and antihypertensive agents against AMD onset and progression.
Characterizes AMD as a vascular disorder wherein impaired choriocapillaris perfusion prevents clearance of RPE-derived lipoproteins, leading to accumulation in Bruch's membrane and drusen.
Identifies increased intravascular pressure and atherosclerotic processes as key mechanical factors impairing choroidal perfusion to the outer retina.
Concludes that the vascular model provides a mechanistic rationale for testing lipid-lowering statins and blood pressure medications as protective therapies for AMD.
