Wet Macular Degeneration

Wet AMD occurs when abnormal blood vessels behind the retina grow under the macula. Wet AMD is also known as choroidal or subretinal neovascularization. The new blood vessels are fragile, and often leak blood and fluid. This leakage causes the macula to be raised from its normal position at the back of the eye, leading to rapid damage.

The loss of central vision associated with wet AMD occurs rapidly. You may first notice that straight lines appear wavy. At the first sign of this symptom, you should immediately have a dilated eye exam.

A person with normal vision will see straight lines in an Amsler Grid, while you would see the lines as wavy if you have AMD. In addition, you may see a dark spot or blurring in the center.

Wet AMD is considered advanced age-related macular degeneration. Although dry AMD does not always turn into wet AMD, if you have wet AMD, you will have had the dry form first. Dry AMD can turn into wet AMD, even in its early stages.

Continuing to self-monitor using the Amsler Grid is even more critical if you have been diagnosed with wet macular degeneration. If you notice a rapid increase in vision distortion on the Amsler Grid, you should make an appointment to see your doctor as soon as possible.
