Age-related macular degeneration AMD
Age-related macular degeneration AMD is a progressive eye disease which appears from the age of 50. A distinction is made between a wet and a dry form.
A genetic predisposition, civilization-related metabolic disorders (such as hypertension, arteriosclerosis, diabetes), irradiation with ultraviolet light and oxidative stress (such as environmental toxins, smoking) are considered to be the causes. Only a small size of approx. 1.5 mm of the retina, so-called macula lutea (“yellow macula” – spot of “sharpest vision“) is affected by macular degeneration. Depending on the form of the disease, this spot is affected by an infiltration of decomposition products, so-called druses (dry AMD), deriving from the cell metabolism or swellings of or bleedings into the retina (wet AMD). Consequences are increasing loss of strength of vision accompanied by the perception of distorted lines, increased blinding sensibility, contrast and color disturbances, central visual field loss and total loss of vision.
