Smoking is a significant risk factor for AMD progression, particularly conversion from which stages?

Smoking is indeed a significant risk factor for the progression of age-related macular degeneration (AMD), particularly in the context of the transformation from dry AMD to wet AMD. Dry AMD is characterized by the presence of drusen and retinal pigmentary changes, while wet AMD is associated with the development of choroidal neovascularization (CNV) and can lead to significant vision loss.

The process of conversion from dry to wet AMD is particularly concerning because wet AMD is often more aggressive in its progression and can result in quicker and more severe vision impairment. Studies have shown that smokers are at a higher risk for this transition due to the damaging effects of tobacco on retinal health, including oxidative stress and inflammation, which can exacerbate the degeneration of retinal tissues.

Consequently, identifying smoking as a risk factor for the conversion of dry to wet AMD underscores the importance of encouraging smoking cessation in patients at risk for AMD.
