Macular Degeneration

Lutein and zeaxanthin-rich foods (most important): dark leafy greens (kale, spinach, collards—highest source, 1-2 servings/day), egg yolks (bioavailable lutein/zeaxanthin—1-2 eggs/day), corn, orange peppers, Omega-3 foods: fatty fish 2-3x/week (salmon, sardines, mackerel—DHA concentrated in retina), walnuts, flax seeds, Colorful vegetables and fruits (antioxidants, vitamins): berries, citrus, carrots, sweet potato, squash, Zinc-rich foods: oysters, beef, pumpkin seeds, chickpeas, Vitamin C and E foods: citrus, bell peppers, nuts, seeds, Mediterranean diet pattern (proven to reduce AMD risk): emphasize vegetables, fruits, whole grains, fish, olive oil, nuts, limit red meat, Avoid: high glycemic foods (sugar, refined carbs—linked to AMD progression), trans fats, processed foods, excessive omega-6 oils (inflammatory), Smoking cessation CRITICAL (smoking doubles AMD risk, accelerates progression—MUST QUIT).

Smoking cessation (MOST IMPORTANT modifiable risk factor): smoking doubles AMD risk, accelerates progression, quitting slows progression even after AMD diagnosed—MUST QUIT (nicotine replacement, medications, counseling), Protect eyes from light: sunglasses 100% UV protection (wear outdoors—UV damage contributes to AMD), blue light filters (computer glasses, screen filters—blue light damages photoreceptors, LED and computer screens high in blue light, especially important if AMD), avoid bright light staring at screens (take breaks every 20 min—20-20-20 rule), Cardiovascular health: control blood pressure, cholesterol, diabetes (vascular health affects retinal circulation), exercise regularly (improves circulation), maintain healthy weight, Mediterranean diet (cardiovascular protective), Nutritional supplementation: AREDS2 formula if intermediate or advanced AMD (proven to slow progression 25%), lutein/zeaxanthin, omega-3 daily, Home monitoring: Amsler grid daily (detects early wet AMD conversion—distortion, missing areas, URGENT if changes occur—call ophthalmologist immediately, wet AMD requires prompt treatment to prevent severe vision loss), Regular eye exams: yearly if early AMD, every 6-12 months if intermediate, more frequent if advanced or high risk, OCT imaging to monitor progression, Low vision aids (if significant vision loss): magnifiers, large print books, talking watches, adaptive technology, vocational rehabilitation, occupational therapy, Wet AMD treatment (only proven treatment): Anti-VEGF injections (Lucentis ranibizumab, Eylea aflibercept, Avastin bevacizumab off-label—all effective, monthly or extended interval dosing, injection into eye—sounds scary but tolerated well, improves or stabilizes vision in 90%, most don't gain vision but prevent further loss, need ongoing indefinitely—stops when wet AMD burns out or vision too poor to benefit, expensive—Lucentis/Eylea $2,000/injection, insurance usually covers, Avastin off-label much cheaper $50 but equally effective), Photodynamic therapy (Visudyne—older treatment, rarely used now, anti-VEGF more effective), Laser photocoagulation (destroys abnormal blood vessels—causes scarring, only for peripheral lesions not near fovea, rarely used), Dry AMD (80-90% of AMD): no proven treatment (anti-VEGF doesn't work, numerous trials failed), AREDS2 supplementation slows progression (only proven intervention), Geographic Atrophy (advanced dry AMD): emerging treatments (complement inhibitors—Syfovre approved 2023, slows growth 30%, injections every 1-2 months, expensive, modest benefit, some risk of wet AMD conversion), Stem cell therapy, gene therapy (experimental—not yet proven).
