Wet macular degeneration

Wet macular degeneration is a chronic eye disease that causes vision loss in the center of your field of vision. Wet macular degeneration is generally caused by abnormal blood vessels that leak fluid or blood into the region of the macula (MAK-u-luh). The macula is in the center of the retina (the layer of tissue on the inside back wall of your eyeball).

Wet macular degeneration is one of two types of age-related macular degeneration. The other type — dry macular degeneration — is more common and less severe. Wet macular degeneration almost always begins as dry macular degeneration. It's not clear what causes wet macular degeneration.

Early detection and treatment of wet macular degeneration may help reduce vision loss and, in some instances, improve vision.

Symptoms Causes Risk factors Prevention

Wet macular degeneration symptoms usually appear and progress rapidly. Symptoms may include:

  • Visual distortions, such as straight lines appearing wavy or crooked, a doorway or street sign looking lopsided, or objects appearing smaller or farther away than they really are
  • Decreased central vision
  • Decreased intensity or brightness of colors
  • Well-defined blurry spot or blind spot in your field of vision
  • Abrupt onset
  • Rapid worsening
  • Hallucinations of geometric shapes, animals or people, in cases of advanced macular degeneration

When to see a doctor

See your eye doctor if:

  • You notice changes in your central vision
  • Your ability to see colors and fine detail becomes impaired

These changes may be the first indication of macular degeneration, particularly if you're older than age 50.
