A new study from Moorfields Eye Hospital and University College London has raised a possible concern for people taking a certain type of blood pressure medicine called Calcium Channel Blockers, or CCBs. These drugs are widely used to help control high blood pressure and are often prescribed to millions of people around the world.
The research team, led by Dr. Alan Kastner, looked at the medical records of more than 427,000 people in the United Kingdom. Among them, over 33,000 were taking CCBs. The team carefully studied each person’s age, lifestyle, and other health issues.
They found something surprising: people who used CCBs had a higher chance of getting glaucoma than people who did not take these medicines.
Glaucoma is a serious eye disease that can damage the optic nerve and cause vision loss. What makes glaucoma tricky is that it often has no clear symptoms in the beginning. This is why it is sometimes called the “silent thief of sight.”
Usually, glaucoma is linked to high pressure inside the eye. But in this study, many of the people who developed glaucoma had normal eye pressure. This suggests that CCBs might affect the eyes in a different way than expected.
This finding is important because CCBs are commonly used. If these medicines are linked to glaucoma, even in people with normal eye pressure, it might mean that doctors need to keep a closer watch on the eye health of patients taking these drugs.
Dr. Kastner and his team are asking for more research to be done to understand how CCBs might lead to glaucoma. They want to know if there is a direct cause or just a link. If more studies confirm this connection, it could change how doctors treat patients with high blood pressure and how often they check for eye problems.
For now, people taking CCBs should not panic or stop their medications without talking to their doctor. But it may be a good idea for them to have regular eye exams to catch any early signs of glaucoma. The earlier glaucoma is found, the better it can be managed to avoid vision loss.
The study also mentioned that some of the researchers had ties to drug companies. This doesn’t mean the results are wrong, but it’s something to keep in mind when reading the study.
The research findings were published in the journal JAMA Ophthalmology. This study gives helpful information for people who are concerned about their eye health, especially those using blood pressure medicine. It reminds us how important it is to stay informed about the possible side effects of the medicines we take and to make sure our health check-ups include all areas of concern.
If you care about blood pressure, please read studies about unhealthy habits that could increase high blood pressure risk, and people with severe high blood pressure should reduce coffee intake.
For more information about blood pressure, please see recent studies that early time-restricted eating could help improve blood pressure, and results showing plant-based foods could benefit people with high blood pressure.
