Macular degeneration is most commonly associated with which factor?

Macular degeneration, particularly age-related macular degeneration (AMD), is primarily linked to advancing age. This condition involves the deterioration of the macula, which is the part of the retina responsible for central vision. As individuals age, the risk of developing AMD increases significantly; statistics indicate that it is most prevalent in individuals over the age of 50.

Other factors such as genetic predisposition, smoking, and dietary influences also play a role, but age is the most significant risk factor. In contrast, while alcohol abuse, diabetes mellitus, and ocular trauma can influence eye health, they are not as directly correlated with the onset of macular degeneration as advancing age. This makes age the most crucial factor to consider when assessing the risk of developing this condition.
