Abstract
Macula r degeneration is a loss of central vision due to progressive degeneration of the macular region of the retina. It is estimated that 25% of those 75 years or older exhibit some age-related macular degeneration (ARMD). Juvenile forms, such as Stargardt's disease, can also strike younger individuals. ARMD can present as a wet (exudative) form involving choroidal neovascularization or a dry (nonexudative) form. Complement-related genes confer susceptibility suggesting that immune-mediated inflammatory responses contribute to ARMD. Oxidative damage to the retinal pigment epithelium may also contribute. Intravitreal injections of anti-vascular endothelial growth factor agents are the primary therapy for wet ARMD.
