Calcium channel blockers tied to glaucoma prevalence
Researchers have identified associations between calcium channel blockers or CCB use and the high prevalence of Glaucoma.
It is already known that Glaucoma is the leading cause of irreversible visual impairment. The only modifiable risk factor for glaucoma onset and progression is Elevated intraocular pressure (IOP).
The older age increases the frequency of comorbidities and polypharmacy. Glaucoma patients also have chronic systemic comorbidities like hypertension and diabetes mellitus (DM).
Researchers investigated the association of commonly used systemic medications with Glaucoma and IOP (European population). The study design was a Meta-analysis of eleven population-based cohort studies of the European Eye Epidemiology (E3) consortium, including 143240 participants and 47177 participants in Glaucoma and IOP analyses, respectively. The main outcomes measured in the study were Glaucoma prevalence and IOP.
They examined associations of four categories of systemic medications (antihypertensive medications: beta-blockers, diuretics, CCBs, alpha-agonists, angiotensin-converting-enzyme inhibitors, angiotensin II receptor blockers; lipid-lowering medications; antidepressants; antidiabetic medications) with glaucoma prevalence and IOP. They also determined Associations with antidiabetic medications were examined in diabetic participants only.
The study results are:
- CCBs were tied to a higher prevalence of Glaucoma.
- There was a stronger association for the monotherapy of CCBs with direct cardiac effects.
- There was no clear association between antihypertensive medications, lipid-lowering medications, antidepressants or antidiabetic medications and Glaucoma.
- There was an association between systemic beta-blocker usage and lower IOP.
- Monotherapy of both selective and non-selective systemic beta-blockers was associated with lower IOP.
- They found an association between high-ceiling diuretics and lower IOP.
- There was no association between the Use of other antihypertensive medications, lipid-lowering medications, antidepressants, or antidiabetic medications and IOP.
They said, “Our study found a potentially harmful association between the use of CCBs and glaucoma prevalence.” The researchers also observed and quantified the association of lower IOP with systemic beta-blocker use.
The results of this study are helpful as glaucoma patients use systemic antihypertensive medications.
The study’s strengths are a large pooled sample size, identification of small effect associations, and good generalizability to European people.
Heterogeneity and cross-sectional design were some of the significant limitations of the study.
