Macular Degeneration is usually age-related. Over time, the macula, a tissue in the retina near the back of the eye, can deteriorate. This can cause blurriness in central vision and in later stages may result in seeing straight or wavy lines. The two types of Age-Related Macular Degeneration (AMD) are dry (atrophic) and wet (advanced neovascular). Atrophic AMD is more common and vision loss is slower, but few treatments exist. Advanced Neovascular AMD results in rapid vision loss, but more treatments are available. In some cases, Atrophic AMD can transition to a late stage of Advanced Neovascular AMD.
