Age-related macular degeneration affects the macula i.e., the central part of the retina which is responsible for seeing final details and central vision. This disease is associated with aging and could gradually destroy sharp, central vision. The central vision is needed for seeing objects clearly and common daily tasks such as reading and driving. The AMD most frequently affects people over the age of 50. The risk factors for AMD are age, gender (more women than men),family history of the disease, cigarette smoking, diet (low consumption of fruits and vegetables), excessive sunlight exposure, obesity, high blood pressure, cardio vascular disease and Alzheimer disease.
Journal articles are most often Primary Research Articles. However, they can also be Review Articles. These types of articles have different aims and requirements. Sometimes, an article describes a new tool or method.
Because articles in scientific journals are specific, meticulously cited and peer-reviewed, journal databases are the best place to look for information on previous research on your species. Without a background in the field, journal articles may be hard to understand - however, you do not need to understand an entire article to be able to get valuable information from it.
