Age-related macular degeneration (AMD) is the leading cause of vision loss among people aged 65 and older in the US. Since the advanced form of this disease affects central vision function, reading difficulties are one of the most common complaints of AMD patients. Most research on reading in AMD has focused on people with advanced disease, who already have significant central vision losses. However, research suggests that reading and other non-standard functional vision measures are affected earlier in the disease, prior to losses in standard visual acuity.
