The so -called ‘good’ cholesterol may not be so beneficial after all and could even leave it blind, with respect to research.
High density (HDL) lipoproteins cholesterol (HDL) has been considered well due to the strip of evidence that shows that it protects the heart.
Eliminates the cholesterol of the arteries and takes it to the liver so that it decomposes and eliminates the body, which reduces the risk of heart attacks and strokes.
But since then some investigations have begun to challenge the opinion that it is better.
Now the scientists, who tracked almost 7,000 British, found higher levels of HDL really increased the risk of incurable ocular condition, glaucoma.
They had 10 percent more likely to develop the condition, which can lead to loss of vision, compared to those with the lowest levels.
On the contrary, participants with the highest levels of low density lipoprotein cholesterol (LDL), typically considered harmful, had 8 percent less likely to develop glaucoma.
However, the risk was only observed in those over 55, said researchers from Sun Yaten University in southern China.

Writing in him British Ophthalmology MagazineThey added: ‘HDL cholesterol has been considered as “good cholesterol” for seven decades.
‘However, this study shows that high levels of (IT) are not constantly associated with a favorable prognosis result.
‘This could cause a reevaluation of lipid management strategies in patients at a glaucoma risk.
“More studies are needed to investigate the mechanisms behind these associations.”
Cholesterol is a fatty and cerosa substance found in blood that is vital for body functions that include digestion, making vitamin D and hormones.
However, too much can be accumulated in the blood due to eating fatty foods, without exercising enough, having overweight, smoking and drinking alcohol.
Having high LDL cholesterol does not trigger any symptoms, but can cause blocked blood vessels and increase the risk of heart problems and stroke.
In the study, the researchers interrogated more than 400,000 British from 40 to 69 years in their health history. Everyone also had blood tests, including those that measured blood fats.

During a 14 -year follow -up, 6,868 (almost 2 percent) developed glaucoma.
Compared to the participants who did not develop glaucoma, those who did were more likely to be former smokers, statin makers and had diabetes, high blood pressure or cardiovascular disease.
But the analysis of the blood test results showed that the highest “good” HDL cholesterol levels specifically associated with a higher risk of glaucoma.
Each increase in HDL levels “associated with a higher 5 percent risk,” they added.
The scientists also recognized that the study had some limitations, including the use only of the blood sample of each participant.
This “may not accurately capture the typical lipid levels of individuals,” they said.
But the findings are based on previous investigations that have suggested that there may be a link between high levels of cholesterol and the increased risk of glaucoma.
Glaucoma is generally caused by the fluid that accumulates slowly in the front of the eye, which increases the pressure inside it.

As a result, the optical nerve, which connects the eye with the brain, is damaged.
Around 700,000 people in the United Kingdom and more than 2 million in the US.
It mainly affects those of the seventies and more, but people of any age can obtain it.
Ocular pain, blurred vision and vomiting are revealing signs of an incurable condition known as the “silent thief of sight.”
However, glaucoma symptoms, which affect two percent of those over 40 in the United Kingdom, may vary considerably.
They can vary from cloudy vision and crying eyes to vomiting.
Glaucoma, which develops slowly for many years in most cases, can lead to loss of vision if it is not treated quickly.
The treatment aims to reduce this pressure through prescribed eye drops, oral medications, laser portraction, surgery or combination of these options.
