Ophthalmologic Disease

Age-Related Macular Degeneration

MODERATE

Progressive degenerative disease of the macula causing central vision loss. Leading cause of irreversible blindness in adults over 50 in developed countries. Dry (atrophic) and wet (neovascular) forms.

Global Affected

196.0M

Countries

111

Symptoms

Blurred central vision
Distorted vision (metamorphopsia)
Dark or empty area in central vision
Difficulty recognizing faces
Need for brighter light
Difficulty adapting to low light
Colors appear less vivid

Treatment Options

Anti-VEGF intravitreal injections
Photodynamic therapy (rarely)
Laser photocoagulation (rarely)
AREDS2 vitamin supplements
Low vision aids
Stem cell therapy (investigational)
Gene therapy (investigational)

Risk Factors

1Age >50
2Family history
3Smoking (strongest modifiable)
4Hypertension
5Obesity
6White race
7High dietary fat intake
8Low lutein/zeaxanthin intake
9Cardiovascular disease
10Genetic variants (CFH, ARMS2)

Diagnostic Methods

  • 1Dilated fundus examination
  • 2OCT (optical coherence tomography)
  • 3Fluorescein angiography
  • 4Amsler grid testing
  • 5Fundus autofluorescence
  • 6Visual acuity testing

Prognosis

Early AMD has slow progression; 10-15% develop advanced AMD over 10 years. Intermediate AMD has higher risk (30-50% over 5 years). AREDS2 supplements reduce progression risk in intermediate AMD. Wet AMD with anti-VEGF therapy (ranibizumab, aflibercept, bevacizumab) maintains vision in 90%+ and improves in 30-40%. Monthly or treat-and-extend injections required long-term. Geographic atrophy (dry AMD advanced form) has no effective treatment yet; complement inhibitors in trials. Low vision aids help advanced disease.

Prevention

  • Smoking cessation
  • AREDS2 supplements (if intermediate AMD)
  • Regular eye exams (age >50)
  • Healthy diet (leafy greens, fish)
  • Blood pressure control
  • Exercise
  • Maintaining healthy weight

Research Status

Anti-VEGF injections (aflibercept, ranibizumab, bevacizumab) standard for wet AMD. Intravitreal gene therapy (RGX-314) in trials. Stem cell therapy for geographic atrophy. AREDS2 supplements slow intermediate AMD. Port delivery system for ranibizumab reduces injection burden.
