High-density lipoprotein (HDL) cholesterol has long been touted as the “good” cholesterol for protecting heart health. However, new research suggests that higher levels of HDL may actually increase the risk of glaucoma, a potentially debilitating eye condition.
Studies have shown that individuals with higher levels of HDL were 10% more likely to develop glaucoma compared to those with lower levels, while those with high levels of low-density lipoprotein (LDL) cholesterol – considered “bad” – were 8% less likely to develop the condition. The risk was observed only in people over the age of 55.
The researchers from Sun Yat-sen University tracked nearly 7,000 Brits and found that glaucoma developed at a rate of 2% over a 14-year follow-up period. The study’s findings suggest that further research is needed to understand the mechanisms behind the association between HDL cholesterol levels and glaucoma risk.
Glaucoma is a leading cause of vision loss worldwide, affecting around 700,000 people in the UK and 2 million in the US. While symptoms can vary, they often include eye pain, blurred vision, and vomiting. Treatment options aim to lower eye pressure through medication, laser treatment, or surgery.
The study’s limitations, including using a single blood sample from each participant, should be noted. However, the findings build on previous research suggesting a link between high cholesterol levels and increased glaucoma risk. As a result, patients at risk for glaucoma may need to reassess their lipid management strategies.
