Treatment for macular degeneration depends on whether it is "dry" or "wet." For dry macular degeneration, we recommend specific antioxidant supplements (the AREDS2 formulation) and lifestyle changes like protecting your eyes from UV light. For the wet form, highly effective treatments include injections in the eye with anti-VEGF medications (such as aflibercept or ranibizumab) to prevent abnormal blood vessel growth and protect your remaining vision. Laser therapies are also occasionally used. I recommend scheduling an exam with your ophthalmologist to confirm which type is affecting your left eye so they can tailor the right plan for you.
