MRI revealed double-layered blebs are common with glaucoma drainage devices. Bleb volume correlates differently with IOP over time, and the PGI forms larger blebs, impacting long-term pressure control.

Cataract surgery consistently lowers intraocular pressure (4.1-8.5 mmHg) and reduces glaucoma medication needs in open-angle glaucoma patients, suggesting potential medication reduction post-surgery.

The PAUL Glaucoma Implant effectively lowered IOP and reduced medication use over one year, showing promise as a safe and effective treatment for moderate to advanced glaucoma.

Automated gonioscopy showed moderate inter-observer agreement for most angle features. This suggests clinical utility but highlights a need for improvement, especially for complex classifications, while simpler binary features are more robust.

LPI significantly reduced headache symptoms in patients with occludable angles, especially those with clinically relevant headaches, suggesting LPI can offer symptomatic relief beyond glaucoma prevention.

This study found Baerveldt-XEN had a lower complete success rate for glaucoma patients at one year compared to Ahmed Valves, suggesting it may be less effective at achieving medication-free IOP control.

This review of NVG surgical outcomes found glaucoma drainage devices safer than cyclophotocoagulation, and trabeculectomy had lower failure rates than Ahmed valves, guiding treatment choices despite limited high-quality evidence.

Marques Raquel Esteves, Ferreira Nuno Pinto, Sousa David Cordeiro, Pinto Joana, Barata André, Sens Paula et al.

This study found that surgeons quickly learned XEN gel implant surgery, with surgical time and complications decreasing significantly by the sixth procedure, indicating a fast learning curve.

Diabetic patients without retinopathy showed a trend of thicker choroids, which also responded differently to ocular pulse amplitude and glycemia compared to non-diabetics, suggesting functional choroidal changes in early diabetes.

Portuguese glaucoma medication prescribing, studied nationwide, revealed 4% of over-40s are treated, with GPs writing most prescriptions but differing from ophthalmologists, impacting care quality and costs.

Abegão Pinto Luís, Willekens Koen, Van Keer Karel, Shibesh Abraham, Molenberghs Geert, Vandewalle Evelien et al.

This large study found glaucoma patients have altered ocular blood flow (e.g., lower retrobulbar velocities) compared to controls, highlighting vascular dysfunction's potential role in clinical glaucoma management.

Van Keer Karel, Abegão Pinto Luís, Willekens Koen, Stalmans Ingeborg, Vandewalle Evelien

This study found a positive correlation between retinal oxygen saturation and choroidal thickness in healthy eyes, but not in glaucoma, suggesting impaired blood flow regulation in glaucoma patients.

Willekens Koen, Abegão Pinto Luís, Vandewalle Evelien, Marques-Neves Carlos, Stalmans Ingeborg

This study found that in normal-tension glaucoma patients, higher optic nerve sheath diameters were associated with lower ocular blood flow velocities, suggesting a potential link to disease pathology.

Vandewalle Evelien, Abegão Pinto Luís, Van Bergen Tine, Spielberg Leigh, Fieuws Steffen, Moons Lieve et al.

This study found intracameral bevacizumab with trabeculectomy significantly reduced the need for additional interventions (like needling) in glaucoma patients, improving absolute surgical success.

Abegão Pinto Luís, Vandewalle Evelien, De Clerck Eline, Marques-Neves Carlos, Stalmans Ingeborg

This study found spontaneous venous pulsation (SVP) is less common in glaucoma, and its absence in normal tension glaucoma (NTG) correlates with more severe damage and altered retinal blood flow, suggesting it's a potential NTG risk indicator.

Abegão Pinto Luís, Vandewalle Evelien, Pronk Anna, Stalmans Ingeborg

This study found optic nerve sheath diameter correlated with IOP only in normal tension glaucoma patients, suggesting translaminar pressure gradient is crucial in NTG pathophysiology.

Glaucoma patients show disturbed, nonlinear relationships between arterial resistance and pulsatility, unlike healthy individuals. This suggests impaired vascular autoregulation, potentially indicating a threshold for microvascular dysfunction.

Abegão Pinto Luís, Vandewalle Evelien, De Clerck Eline, Marques-Neves Carlos, Stalmans Ingeborg

Ophthalmic artery Doppler waveforms are altered in glaucoma, showing lower Sm/Dm ratios and ESA, correlating with visual field loss and nerve damage, suggesting vascular dysfunction contributes to disease progression.
