Small white or yellowish spots on the retina is a sign of dry age-related macular degeneration.

Explanation:

If you have dry age-related macular degeneration, small white or yellowish spots called form on the retina, causing the macula to deteriorate over time.

2

Leaking blood vessels under the retina is a sign of wet macular degeneration.

Explanation:

If you have wet macular degeneration, abnormal blood vessels under the retina begin to grow toward the macula, then break and leak fluid.

What is Macular Degeneration and How Do You Know if You Have It?

It affects the macula, which is a small but critical part of the retina responsible for sharp, central vision.

There are two main types of macular degeneration: dry AMD and wet AMD. Dry AMD is the more common form, accounting for about 85-90% of cases. It is characterized by the gradual breakdown of the macula, resulting in the formation of small, yellowish deposits called drusen. Dry AMD typically progresses slowly and may cause mild to moderate vision loss.
