Call waiting

Seeing is believing

Q: My vision is okay right now, but my doctor has told me to watch out for macular degeneration. My daughter told me that there are different forms of it, though. Can you explain the forms to me so that I know what exactly I'm watching out for?

JVW: Macular degeneration has two forms: wet and dry.

The "dry" form of macular degeneration is much more common than the "wet" variety and is characterized by loss of pigment in the retina and the formation of small, yellowish deposits within the layers of the retina that make it difficult to see.

The "wet" form involves growth of abnormal blood vessels under the retina and macula. These blood vessels may then bleed and leak fluid, causing the macula to bulge or lift up which causes distorted vision and potentially rapid, severe vision loss. What is...the macula?

The macula is a small spot located on the retina of the eye that is responsible for central vision.
