Insights
Glaucoma is linked to cardiovascular disease (CVD) and impaired ocular blood flow. Patients with primary open-angle glaucoma (POAG) and normal-tension glaucoma (NTG) show more cardiovascular risks and poorer ocular perfusion.
Area of Science:
- Ophthalmology
- Cardiology
- Vascular Biology
Context:
- Glaucoma is a leading cause of irreversible blindness.
- Cardiovascular disease (CVD) and ocular hemodynamic variables (OHV) are potential risk factors for glaucoma.
- Understanding the interplay between systemic vascular health and ocular perfusion is crucial for glaucoma management.
Purpose:
- To investigate the association between glaucoma and cardiovascular disease (CVD).
- To examine ocular hemodynamic variables (OHV) in patients with glaucoma.
- To explore the relationship between cardiovascular risk factors (CVRF) and glaucoma.
Summary:
- A cross-sectional study of 73 patients (25 controls, 28 with primary open-angle glaucoma (POAG), 20 with normal-tension glaucoma (NTG)) assessed CVRF, CVD, and OHV.
- Patients with POAG and NTG exhibited a higher prevalence of CVRF and CVD compared to controls.
- Glaucoma patients demonstrated altered OHV, including reduced blood flow velocities and increased vascular resistance in ocular arteries.
Impact:
- The findings highlight a significant association between CVD/CVRF and glaucoma.
- Altered OHV in glaucoma patients suggest compromised ocular perfusion.
- This research underscores the importance of considering systemic vascular health in the context of glaucoma.
Background And Objective:
We sought to study the association of glaucoma with vascular disease, with 2 independent pathways: the association of glaucoma with cardiovascular disease (CVD) and the study of ocular hemodynamic variables (OHV) in glaucoma.
Material And Method:
Cross-sectional study consisting of 73 patients: 25 without glaucoma, 28 primary open-angle glaucoma (POAG) and 20 normal-tension glaucoma (NTG). OHV, cardiovascular risk factors (CVRF) and CVD were determined.
Results:
We found a greater number of CVRF and CVD in patients affected by POAG (P=.002 and P=.016) and NTG (P=.001 and P=.010) compared to the control group. With regard to OHV, in patients suffering from POAG, we found lower systolic and diastolic velocities and higher resistance index in the central retinal artery (P<.05). Moreover, in both types of glaucoma, we found higher resistance index in the posterior ciliary artery (P<.05).
Conclusions:
There is a statistically significant association between the presence of CVD and/or CVRF and glaucomatous disease, a finding that is supplemented with data from the OHV. These values indicate a worst ocular perfusion in patients with glaucomatous disease.
