ABSTRACT
Age-related macular degeneration (AMD) is the leading cause of
worldwide blindness for the elderly in the western world. It is
a bilateral ocular condition that affects the central area of retina
known as the macula. Although the macula comprises less than 5%
of the retinal area, it is responsible for the central acute vision.
The fovea lies at the center of the macula and is approximately
2 mm in diameter. The fovea contains the highest density of cone
photoreceptor cells and is the only region of the retina where 20/20
vision is attainable. Thus, lesions developing in this region can have
a major impact on visual function.
