Geographic Atrophy

Geographic atrophy is an advanced form of dry age-related macular degeneration. It causes a gradual loss of central vision, affecting the ability to read, drive, and recognize faces, while peripheral vision is typically preserved.

Overview

A clear starting point

Geographic atrophy is a serious, advanced stage of dry age-related macular degeneration (AMD) that primarily affects the macula, the part of the retina responsible for sharp, central vision. As the condition progresses, it causes the gradual breakdown of retinal cells, leading to blind spots and a permanent decline in central visual acuity. While peripheral vision is usually maintained, the loss of central vision can significantly impact daily activities such as reading, driving, and recognizing faces. The exact cause involves a combination of aging, genetics, and environmental factors like smoking. Although there is currently no cure, emerging treatments aim to slow the progression of retinal damage.

Four key facts

  1. 1Geographic atrophy is a late stage of dry age-related macular degeneration that affects the macula of the retina.
  2. 2It leads to a progressive and permanent loss of central vision, though peripheral vision usually remains intact.
  3. 3Risk factors include advancing age (typically over 60), family history, smoking, and certain cardiovascular conditions.
  4. 4While there is no cure, recent FDA-approved therapies may help slow the progression of the condition.

Useful points to discuss

Avoid smoking or seek support to quit, as it is a major modifiable risk factor for macular degeneration.
Maintain a healthy lifestyle with a diet rich in dark leafy greens and manage chronic conditions like high blood pressure.
Schedule regular comprehensive eye exams to monitor vision changes and discuss potential management options with an eye care specialist.

When professional care may be important

These examples are not a diagnosis checklist. New, severe, rapidly worsening, or concerning symptoms should be assessed by a qualified healthcare professional; emergencies require local emergency services.

  • Sudden increase in blurry or distorted central vision.
  • Appearance of new dark spots or blank areas in the center of your vision.
  • Flashes of light or floaters that seem to appear suddenly.
