Arterial Stiffness and Incident Glaucoma: A Large Population-Based Cohort Study

Area of Science:

• Ophthalmology
• Cardiovascular Medicine
• Epidemiology

Background:

• Arterial stiffness is an indicator of cardiovascular health.
• Glaucoma is a leading cause of irreversible blindness.
• Early identification of glaucoma risk factors is crucial for timely intervention.

Purpose of the Study:

• To determine if arterial stiffness, assessed using oscillometric methods, is associated with the incidence of glaucoma.
• To evaluate specific measures of arterial stiffness, including aortic pulse wave velocity (aPWV), estimated carotid-femoral PWV (ePWV), and aortic pulse pressure (aPP).

Main Methods:

• A prospective, population-based cohort study involving 4,713 participants aged 50-84 without known glaucoma.
• Arterial stiffness was measured using aPWV, ePWV, and aPP.
• Incident glaucoma was identified through national health registers over a mean follow-up of 10.5 years.
• Cox proportional hazards regression was used to analyze the association between arterial stiffness and glaucoma risk.

Main Results:

• Increased arterial stiffness, specifically higher aPWV and ePWV, was significantly associated with a greater risk of developing glaucoma.
• Participants in the highest quartiles of aPWV and ePWV had a substantially elevated risk of incident glaucoma.
• While aPP showed a trend, only aPWV and ePWV demonstrated statistically significant associations with glaucoma incidence.

Conclusions:

• Arterial stiffness, readily measured by oscillometric devices, serves as a predictive marker for incident glaucoma.
• These findings suggest that arterial stiffness assessment could be integrated into clinical practice for glaucoma risk stratification.
• This research opens potential avenues for therapeutic interventions targeting arterial stiffness to prevent or manage glaucoma.
