Which type of macular degeneration is considered non-preventable?

Non-exudative (dry) macular degeneration is considered non-preventable primarily due to its association with aging and genetic factors. This form of macular degeneration involves the gradual breakdown of retinal cells and the accumulation of drusen — small yellow spots in the retina — which are typically linked to the aging process. As individuals age, they are inherently at a higher risk for developing this type of macular degeneration, and there are no proven preventive measures that can entirely avert its onset.

In contrast, exudative (wet) macular degeneration, though often more severe and leading to quicker vision loss due to the formation of new, abnormal blood vessels under the retina, involves additional risk factors that could potentially be managed or modified (such as lifestyle changes that could mitigate risk factors for vascular diseases).

Therefore, since non-exudative macular degeneration is intrinsically related to natural aging and genetic predisposition, it is deemed non-preventable. Understanding this distinction is crucial for both patient education and for strategies aimed at managing age-related eye health.
