What is the main difference between dry AMD and wet AMD?

The correct answer highlights that wet age-related macular degeneration (AMD) involves the formation of abnormal blood vessels under the retina. In wet AMD, these blood vessels can leak fluid and blood, leading to significant and rapid vision loss. This condition is typically more severe than dry AMD and can result in more significant visual impairment.

Dry AMD, on the other hand, is characterized by the gradual thinning of the retina and the presence of drusen (yellow deposits), which usually causes a more gradual loss of vision over time rather than sudden vision loss. While dry AMD is the more common form, it is generally considered less serious than wet AMD due to its slower progression.

Recognizing this distinction is vital in clinical practice, as wet AMD often requires more aggressive treatment, while dry AMD may only necessitate monitoring and lifestyle changes. Understanding the differences between these two forms is essential for proper diagnosis and management in patients experiencing age-related vision issues.
