Wet macular degeneration (WMD)

Definition

Wet macular degeneration (WMD) is an eye condition that leads to the deterioration of the central portion of the retina, known as the macula. It is characterized by abnormal blood vessel growth under the retina which can leak fluid or blood.

5 Must Know Facts For Your Next Test

1. WMD is more severe and less common than dry macular degeneration.
2. Anti-VEGF medications are commonly used for treatment to inhibit abnormal blood vessel growth.
3. Symptoms include blurred vision, dark spots in central vision, and distortion of straight lines.
4. Early diagnosis and treatment are crucial to preventing significant vision loss.
5. Risk factors include age, smoking, high blood pressure, and genetic predisposition.
