As dry AMD deteriorates the central vision, you may see a blurred spot. This occurs because a large group of cells in the macula have stopped working. Over time, the spot will enlarge and become darker, giving you loss of central vision. Those who suffer from dry AMD in only one eye often do not notice a change in their vision. With one good eye, they can see fine details and still drive and read.
Some people only notice a change in their vision when both eyes have been affected.
Wet AMD has early warning signals. Straight lines may appear wavy. This happens when the new blood vessels leak fluid under the macula. The fluid moves the macula out of position at the back of the eye and vision is distorted. Another symptom of wet AMD is rapid loss of central vision.
