A recent study raises concerns for individuals using a popular blood pressure medication, Calcium Channel Blockers (CCBs).
The research suggests that those taking CCBs may face an increased risk of developing glaucoma, a severe eye condition that can lead to blindness if not treated properly.
Led by Dr. Alan Kastner at Moorfields Eye Hospital and University College London, the study scrutinized the health records of over 427,000 UK adults.
Among these, 33,175 were on CCBs. The findings are alarming: even after adjusting for various factors like age, lifestyle, and existing health conditions, people on CCBs had a higher likelihood of being diagnosed with glaucoma.
What sets this study apart is that it found this association specifically with CCBs and not other types of blood pressure medications. More so, the research uncovered that those on CCBs exhibited signs of early glaucoma stages, despite having normal eye pressure levels.
Glaucoma typically results from increased pressure within the eye, damaging the optic nerve. This new finding suggests that CCBs may impact the eyes through a different, unknown process. The study underscores the complexity of how medications can affect our health in unexpected ways.
Given the silent progression of both high blood pressure and glaucoma—often going unnoticed until significant damage has occurred—this potential link is particularly concerning. It emphasizes the need for regular eye exams, especially for those at increased risk of glaucoma.
Dr. Kastner and his team are calling for more research to delve deeper into the relationship between CCBs and glaucoma.
Until more is known, it’s crucial for those taking CCBs to discuss these findings with their doctors. Balancing the benefits of controlling blood pressure against the possible risks to eye health is key.
The study, though comprehensive, leaves room for further investigation, particularly given some researchers’ connections to the pharmaceutical industry.
However, the findings published in JAMA Ophthalmology are a valuable resource for medical professionals and patients alike, highlighting the importance of being well-informed about medication side effects.
For those concerned about their eye health, this study serves as a reminder to maintain open communication with healthcare providers and stay informed about the medications they take.
If you care about high blood pressure, please read studies that early time-restricted eating could help improve blood pressure, and coconut sugar could help reduce blood pressure and artery stiffness.
For more information about blood pressure, please see recent studies about added sugar in your diet linked to higher blood pressure, and results showing plant-based foods could benefit people with high blood pressure.
