Many people take medicine every day to lower their blood pressure and protect their heart.
But a new study suggests that one common type of medicine might be linked to a serious eye problem called glaucoma. This finding has raised concerns, especially because so many people rely on this kind of medicine to stay healthy.
The study was done by researchers at Moorfields Eye Hospital and University College London in the UK. They looked at the health records of more than 427,000 adults in the country.
Among them, over 33,000 were taking a type of blood pressure medicine called Calcium Channel Blockers, or CCBs for short. These drugs help relax the blood vessels, which makes it easier for the heart to pump blood and lowers blood pressure.
After looking carefully at the data and removing the effects of other things like age, smoking, and other illnesses, the researchers found something important. People who took CCBs were more likely to have glaucoma than people who did not take this kind of medicine.
This link was not seen in people taking other types of blood pressure drugs, which made the researchers even more curious.
Glaucoma is a disease that damages the optic nerve in the eye, and it often happens when there is too much pressure inside the eye. It can slowly take away a person’s vision, and many people don’t know they have it until the damage is serious.
What was surprising in this study is that the increased risk of glaucoma was seen even in people who had normal eye pressure. This means CCBs might affect the eyes in a different way that doesn’t involve pressure.
This is worrying because CCBs are very commonly used. If they do raise the risk of glaucoma, it could affect a large number of people. Doctors might need to be more careful when prescribing them, especially for people who already have other eye problems or a family history of glaucoma.
The study shows how important it is to have regular eye check-ups, especially for people taking blood pressure medicine. Since glaucoma often has no early symptoms, eye tests are the only way to catch it before it causes permanent damage.
The researchers say more studies are needed to fully understand if CCBs actually cause glaucoma or if something else is going on. They also want to learn how these drugs might affect the eyes.
If you are taking CCBs, don’t stop your medicine without talking to your doctor. But you should feel free to ask about this new research and whether it might affect you. Your doctor can help you decide if you need extra eye exams or if another type of medicine might be better for you.
Some of the researchers who worked on the study have connections to drug companies. While this doesn’t mean the study is wrong, it’s something to keep in mind when thinking about the results.
The full study was published in the journal JAMA Ophthalmology. It provides helpful information for people who are concerned about how their blood pressure medicine might affect their eyes.
