Wet Macular Degeneration
Wet (neovascular or exudative) macular degeneration accounts for approximately 10 percent of the cases of age-related macular degeneration. However, it results in 90 percent of the cases of legal blindness. All wet macular degeneration is considered advanced.
- The Bruch's membrane begins to break down, usually near drusen deposits, and new blood vessels grow.
- This growth is called neovascularization. These vessels are very fragile and can leak fluid and blood.
- The leaks result in scarring of the macula and the potential for rapid, severe damage.
- Straight-ahead vision can become distorted or lost entirely in a short period of time, sometimes within days or weeks.
