Understanding AMD: The Leading Cause of Vision Loss
Age-related macular degeneration (AMD) is the primary cause of vision loss in individuals over 50 in developed nations like the United States. Early detection and treatment are vital, as delayed diagnosis can significantly impact visual function. AMD has two forms: dry and wet.
Types of AMD
Dry AMD
Characterized by drusen buildup (yellow deposits under the retina), dry AMD usually doesn’t cause severe vision loss unless it progresses to the wet form. Regular monitoring is crucial.
Wet AMD
Responsible for 90% of severe vision loss in AMD patients, wet AMD involves abnormal blood vessel growth under the retina. Symptoms include central vision deterioration, blind spots, and distorted vision.
Diagnosis & Classification
Precise diagnosis involves:
- Fluorescein angiography
- Ocular coherence tomography
- Color fundus photography
The location of neovascular lesions (subfoveal vs. non-subfoveal) determines the risk of vision loss.
Managing AMD: Dry vs. Wet
Dry AMD Management:
The AREDS2 formulation (vitamin C, vitamin E, lutein, zeaxanthin, zinc, and copper) may reduce the risk of progression to advanced AMD. For patients with geographic atrophy (advanced dry AMD), Syfovre (pegcetacoplan) is an FDA-approved intravitreal injection that slows the growth of these lesions. For select candidates, we also offer Valeda Light Delivery System photobiomodulation (PBM) therapy, a non-invasive light-based treatment for earlier-stage dry AMD.
Wet AMD Treatment Options:
Anti-VEGF Injections: Intravitreal injections of medications like Eylea (aflibercept), Eylea HD (aflibercept), Vabysmo (faricimab-svoa) or Avastin (bevacizumab) block abnormal blood vessel growth. These are often repeated monthly.
