They also tended to have higher blood pressure, higher body mass index (BMI), and were more likely to have diabetes, all of which are known risk factors for the condition.
When the researchers looked at the associations between blood fat levels and the risk of glaucoma, they found that higher levels of HDL cholesterol were associated with a heightened risk of developing the condition. Specifically, every 1 mmol/L increase in HDL cholesterol was associated with a 6% increased risk of glaucoma.
In contrast, higher levels of LDL cholesterol were associated with a lower risk of glaucoma. Specifically, every 1 mmol/L increase in LDL cholesterol was associated with a 6% decreased risk of glaucoma.
The researchers suggest that HDL cholesterol may be linked to glaucoma because it is involved in the transport of cholesterol around the body, including to the eye, where it may contribute to the build-up of deposits in the drainage channels, leading to increased pressure within the eye.
On the other hand, LDL cholesterol may be protective against glaucoma because it is involved in the transport of cholesterol away from the eye, helping to prevent the build-up of deposits in the drainage channels.
The researchers acknowledge that their study has some limitations, such as being observational in nature, so it cannot prove causation. However, they believe that their findings warrant further investigation to determine whether managing blood fat levels could help prevent or slow the progression of glaucoma.
In conclusion, the study suggests that the relationship between cholesterol levels and glaucoma is more complex than previously thought, with HDL cholesterol potentially being a risk factor and LDL cholesterol potentially being protective. Further research is needed to confirm these findings and explore potential treatment options for individuals at risk of developing glaucoma.
