Genetic Correlation and Mendelian Randomization Analyses Reveal Causal Links Between Metabolic-Associated Diseases or Risk Factors and Major Eye Diseases.

Summary: Did you know that your body's metabolism can affect your eyesight? Scientists looked at the DNA of over 500,000 people to see if conditions like high blood pressure, diabetes, and cholesterol are linked to eye problems. They discovered that having high blood pressure can actually cause cataracts as you get older. Surprisingly, having high "good" cholesterol (HDL) might increase the risk of a disease called AMD, while "bad" cholesterol (LDL) might actually protect against it! Type 2 diabetes was also linked to a higher chance of getting cataracts and glaucoma. This research helps doctors understand how keeping the rest of the body healthy can protect our eyes.
