A 79-year-old female with a history of dry age-related macular degeneration reports seeing dark spots in her central field of vision over the past week. What could be the cause?
The appearance of dark spots in her central field of vision could suggest that her condition has progressed to wet (neovascular) age-related macular degeneration. This progression occurs when new, abnormal blood vessels grow under the macula and leak fluid and blood, causing symptoms such as dark spots or loss of central vision.
