What is age-related macular degeneration?
Age-related macular degeneration (AMD) is a disease that progressively damages the macula. The macula is the central part of the retina that helps us see fine details and small things. At first, macular degeneration can appear as a distortion in vision (like when objects look bent or crooked). As the disease progresses, the central vision is lost leaving only the peripheral vision (on the sides) unaffected.
In the western world, age-related macular degeneration is very common and one of the leading causes of vision loss in people over 50 years old.

How is age-related macular degeneration diagnosed?
Early detection limits the progression of the disease and helps preserve vision. To diagnose age-related macular degeneration, a retina specialist must examine the back of the eye where the retina is located. Depending on the form (dry or wet) and the stage of the disease, your eye doctor can request some additional tests to decide the best treatment.

What is the treatment for age-related macular degeneration?
The progression of age-related macular can be delayed from an early to an advanced stage with food supplements with antioxidants prescribed by a retina specialist.
The dry form of age-related macular degeneration evolves slowly over several years. Many treatments are currently in pre-clinical research phases and the findings are to be released soon.
The wet form of age-related macular degeneration progresses more rapidly due to the formation of abnormal veins below the macula (causing hemorrhages and fluid accumulation). Urgent treatment is necessary to maintain or restore vision. Currently, the first-line treatment is the repeated injection of therapeutic proteins known as anti-VEGF.
