Age Related Macular Degeneration


Macular degeneration, often called AMD or ARMD (age-related macular degeneration), is the leading cause of vision loss and blindness.

AMD occurs with degeneration of the macula, which is the part of the retina responsible for the sharp, central vision needed to read or drive. Because the macula primarily is affected in AMD, central vision loss may occur.

Macular degeneration is diagnosed as either dry (non-Neovascular) or wet (Neovascular). Neovascular refers to growth of new blood vessels in an area, such as the macula.

1. Dry Macular Degeneration (non-Neovascular). Dry AMD is an early stage of the disease and may result from the aging and thinning of macular tissues, depositing of pigment in the macula or a combination of the two processes.

2. Wet Macular Degeneration (neovascular). With wet macular degeneration, new blood vessels grow (neovascularization) beneath the retina and leak blood and fluid. This leakage causes permanent damage to light-sensitive retinal cells, which die off and create blind spots in central vision.



1. Macular degeneration usually produces a slow, or rarely, sudden painless loss of vision.

2. Early signs of vision loss from AMD include shadowy areas in your central vision or unusually fuzzy or distorted vision

Macular degeneration mainly affects central vision, causing "blind spots" directly ahead.



1. Vitamins A, C and E- help lower the risk for AMD or slow down the progression of dry macular degeneration.

2. For wet AMD, treatments aimed at stopping abnormal blood vessel growth include FDA-approved drugs of Lucentis, Macugen and Visudyne used with Photodynamic Therapy or PDT.
