A study published in the British Journal of Ophthalmology revealed that the regular use of medications to lower cholesterol and manage type 2 diabetes can reduce the risk of AMD, a degenerative eye condition associated with aging. Previously, several studies have suggested that medications to lower cholesterol, manage diabetes, and reduce inflammation can reduce the chances of developing AMD; however, the data was found to be inconsistent due to the small subject group.

In this pooled analysis study, the data from 14 population-based and hospital-based studies, which included 38,694 participants, was used. The studies used in this trial were a part of the European Eye Epidemiology (E3) project. All the participants in the study were over 50 and were receiving at least one medication, namely, levodopa used to treat movement difficulties brought on by neurodegenerative diseases, statins to lower cholesterol, insulin to regulate diabetes, or/and steroids to reduce inflammation.

The findings of the study showed that the prevalence of AMD ranged from 12.5% to 64.5%. On the other hand, the prevalence of advanced (late) AMD ranged from 0.5% to 35.5%, totaling 951 cases. After statistically adjusting for the potentially influential factors, the data analysis revealed that medications to lower cholesterol or control diabetes were related to a lower prevalence of any type of AMD by 15% and 22%, respectively.
