Which answer describes the typical behavior of multifocal Geographic Atrophy lesions?

The typical behavior of multifocal Geographic Atrophy (GA) lesions is best characterized by their progression at a higher rate. Geographic Atrophy, associated with conditions like age-related macular degeneration (AMD), presents as distinct areas of retinal pigment epithelium (RPE) atrophy. The multifocal nature of these lesions means they are not only present in multiple locations but also can expand over time.

As these lesions grow, they can lead to significant visual impairment due to the loss of photoreceptors and RPE. The progression rate can vary among patients, but generally, multifocal GA lesions are recognized for their tendency to expand and coalesce, leading to greater areas of atrophy. This characteristic distinguishes them from other types of retinal lesions that may stabilize more quickly or show more erratic growth patterns. Understanding this behavior is essential for anticipating disease progression and planning appropriate monitoring and management strategies for affected patients.
