A new study has found that some people taking common blood pressure medicine may face a higher risk of getting glaucoma, an eye disease that can cause blindness.
The research was done by Dr. Alan Kastner and his team at Moorfields Eye Hospital and University College London.
The study looked at a group of medicines called Calcium Channel Blockers, or CCBs. These are often used to treat high blood pressure. The team studied health records from more than 427,000 people in the UK. Out of these, over 33,000 people had taken CCBs.
The researchers checked things like the age, health conditions, and lifestyle of each person. They found that people who used CCBs were more likely to have glaucoma than those who didn’t use them. This was surprising because some of these people had normal eye pressure, which is not usually linked to glaucoma.
Glaucoma is a serious disease that damages the nerve in your eye. It is usually caused by high pressure inside the eye. But this study suggests that CCBs may cause glaucoma in another way, even if eye pressure is normal.
This is important news because CCBs are used by many people around the world. Glaucoma is often called the “silent thief of sight” because it does not show clear signs until your vision is already damaged. That’s why early eye checks are important, especially for people taking CCBs.
The scientists are not yet sure if CCBs directly cause glaucoma. They say more research is needed to confirm this and to understand how the medicine could be linked to the disease.
People who take CCBs should not panic, but it may be a good idea to talk to their doctor and get regular eye exams. If glaucoma is found early, treatment can help protect your vision.
It’s also worth noting that some of the scientists who worked on this study have connections to drug companies. This does not mean the study is wrong, but it is something readers should be aware of.
The full results of the study were published in a medical journal called JAMA Ophthalmology. The study helps remind us all to stay informed about our medicine and health.
