Age-related macular degeneration (AMD) is the leading cause of blindness among Americans. Local inflammation is implied in the pathophysiology of AMD that may cause photoreceptor destruction and blindness. Vitamin D may prevent AMD progression via its anti-inflammatory and antiangiogenic properties. Scientific evidence is discussed for the associations of vitamin D (serum, diet, and sunlight) and AMD. Evidence suggests inverse associations between serum vitamin D and its sources (specifically fish), and AMD. Associations with sunlight, hypothesized to increase risk for AMD, have been inconsistent possibly due to protection from vitamin D. Vitamin D may be a new protective factor against AMD.
