How Blood Pressure Fluctuations Can Worsen Glaucoma

Original Article: https://jamanetwork.com/journals/jamaophthalmology/article-abstract/2826006

What the Study Found

A new study shows that patients with large fluctuations in blood pressure over time experience faster vision loss due if they also have glaucoma. Researchers found that both higher variability and interactions between blood pressure and eye pressure (intraocular pressure) contribute to quicker progression of loss of visual fields. These findings highlight the importance of managing blood pressure as part of glaucoma care. 

How the Study Was Done 

The study analyzed data from 985 people with suspected or confirmed glaucoma, using information from over 20 years. Blood pressure and vision changes were tracked across thousands of tests. Researchers identified that fluctuations in diastolic and mean arterial blood pressure were closely linked to how quickly vision worsened.  

Why It Matters for Patients

This study suggests that managing blood pressure variability is critical for slowing glaucoma progression. Doctors may need to adopt a more holistic approach, combining careful blood pressure monitoring with eye care to protect vision. However, the research was limited by factors like the use of office-only blood pressure readings and the absence of data on antihypertensive medications.
