New study suggests link between cholesterol levels and glaucoma risk

New research from the United Kingdom suggests that cholesterol, which has long been associated with heart health, may also play a role in glaucoma, a progressive eye disease that can lead to permanent vision loss and blindness.

Glaucoma affects more than 80 million people worldwide and is often marked by symptoms like eye pain, headaches, and blurred vision. The disease causes a buildup of pressure behind the eye, which, over time, can damage the optic nerve. Once that damage occurs, it is irreversible.

While age and family history have long been known as key risk factors, the new study found that participants with higher levels of "good" cholesterol (HDL) were 10% more likely to develop glaucoma. On the other hand, those with elevated levels of "bad" cholesterol (LDL) had an 8% reduced risk.

Medical professionals caution against drawing immediate conclusions, saying more clinical trials are needed to fully understand the connection. However, experts stress that the findings should encourage people, especially those over 40 or with a family history of glaucoma, to undergo annual eye exams.

Cholesterol can be managed through medication or lifestyle changes, such as reducing saturated fats, increasing soluble fiber, and adding omega-3-rich foods like salmon and walnuts to the diet. Experts also emphasize the importance of staying physically and mentally active to support overall health.

While researchers continue to investigate the possible connection, the study serves as a reminder that maintaining balanced cholesterol levels and keeping up with regular health screenings can have wide-ranging benefits beyond heart health.
