Age-related Macular Degeneration (AMD) is not uncommon. In fact, AMD is the leading cause of severe vision loss in people over the age of 60.
Overall it is a progressive eye disease that damages the macula. The macula is the part of the eye responsible for central vision, which is needed to perform straight-ahead activities, such as:
A person diagnosed with AMD has either dry AMD or wet AMD. Although wet AMD is far less common than the dry type, it is responsible for about 85% of severe vision loss. That's why it's important to visit your eye doctor on a regular basis. It's the best defense to help preserve your vision.
When abnormal vessels leak fluid and/or blood under the macula, vision loss occurs because of damage and disruption to the retinal tissue. This damage often rapidly advances over time, affecting more of your vision. That is why it is so important for you to commit to a treatment plan with your eye care professional and stick to your regularly scheduled visits.
Macular Degeneration comes in two basic types: dry and wet. Approximately 85% to 90% of the cases of Macular Degeneration are the dry (atrophic) type, while 10-15% are the wet (exudative) type. Wet AMD starts out as dry AMD. Dry AMD is the early form in which proteins build up in the retina.
Scientists think that the body recognizes that the dry AMD is disrupting the circulation of blood in the eye, preventing oxygen and nutrients from reaching the retina. In response, a growth factor is triggered, which causes blood vessels to grow in the eye, leading to wet AMD.

VISUDYNE® (verteporfin for injection) is used along with laser light treatment to stop leaking from blood vessels in the eye due to the following serious eye conditions: age-related macular degeneration (a condition affecting the retina of the eye which can impair vision), pathologic myopia (extreme nearsightedness) or ocular histoplasmosis (a certain type of fungus infection in the eye).
