What Is the Difference Between Wet and Dry AMD?

Diagram shows the differences between a healthy eye, an eye with dry AMD and an eye with wet AMD Age-related macular degeneration (AMD) is a leading cause of vision loss in people over the age of 50. The condition affects the macula, the central part of the retina responsible for sharp, detailed vision. AMD is categorized into two types: wet and dry. At North Suburban Eye Associates, our team of highly trained and respected ophthalmologists helps patients manage AMD with advanced diagnostic tools and personalized care. In this blog, we discuss some of the differences between AMD types.

What Is Dry AMD?

Dry AMD is the more common form of the condition, accounting for about 85–90% of cases. It occurs when the macula thins over time due to aging, causing the gradual breakdown of light-sensitive cells. Patients with dry AMD may notice blurry or reduced central vision, making tasks like reading or driving more challenging. This type progresses slowly, and early stages may not cause noticeable symptoms. Regular eye exams are essential for detecting and monitoring dry AMD.

Understanding Wet AMD

Wet AMD, while less common, is more severe and progresses rapidly. This form develops when abnormal blood vessels grow beneath the retina. These vessels can leak fluid or blood, causing sudden vision loss or distortion. Symptoms of wet AMD often include wavy or blurred central vision, dark spots, or rapid changes in visual clarity. Early treatment is critical to managing wet AMD and preserving vision.

Key Differences Between Wet and Dry AMD

  • Progression: Dry AMD develops slowly over years, while wet AMD can lead to significant vision loss in a short time.
  • Symptoms: Dry AMD causes gradual central vision blurriness; wet AMD often results in sudden vision distortion or dark spots.
  • Cause: Dry AMD involves the gradual thinning of the macula, while wet AMD is caused by abnormal blood vessel growth.
  • Treatment: Dry AMD currently has no cure, but lifestyle changes and supplements can slow its progression. Wet AMD is treated with anti-VEGF injections, laser therapy, or photodynamic therapy to stop or slow the growth of abnormal blood vessels.
