This study found that lower baseline peripapillary OMAG (perfusion/vessel density) was associated with faster ganglion cell loss in mild-moderate glaucoma, suggesting OMAG may predict disease progression.

This study found a smartphone-based perimeter (GearVision) had good agreement with standard HFA and was preferred by patients, suggesting its potential for portable or home glaucoma monitoring.

In PACG, lower retinal vessel density measured by OCTA is linked to faster visual field decline, suggesting OCTA can help identify patients at higher risk of progression.

SITA Faster visual fields were significantly quicker than SITA Standard, showing comparable diagnostic parameters and good agreement. This makes SITA Faster a viable, efficient option for glaucoma diagnosis and monitoring.

OCTA in glaucoma reveals reduced vessel density and microvascular dropout, correlating with functional/structural damage. It complements existing tests for diagnosis, progression, and risk assessment, especially in advanced disease.

Pradhan Zia S, Rao Harsha L, Dixit Shivani, Sreenivasaiah Shruthi, Reddy Praveena G, Venugopal Jayasree P et al.

This study found choroidal microvascular dropout is significantly less common in pseudoexfoliation glaucoma than in severity-matched primary open-angle glaucoma, suggesting different underlying vascular pathology.

Rao Harsha L, Sreenivasaiah Shruthi, Dixit Shivani, Riyazuddin Mohammed, Dasari Srilakshmi, Venugopal Jayasree P et al.

This study found choroidal microvascular dropout (CMvD) is significantly more prevalent in glaucoma eyes with disc hemorrhage and linked to central vision loss, suggesting a microvascular component in these cases.

This study found choroidal microvascular dropout (CMvD) is less prevalent in PACG than POAG, but in both, it links to advanced visual field damage, especially parafoveal scotomas, implying shared vascular pathology.

Glaucoma patients with intact visual fields showed reduced vessel density and structural thinning in these "healthy" regions, suggesting vascular changes can precede functional decline.

This study found macular ganglion cell-inner plexiform layer thickness is significantly better than optical microangiography vessel parameters for diagnosing glaucoma, especially compared to the 3x3mm scan.

This study found macular microcirculation (OMAG), nerve layer thickness (GCIPL), and vision loss in glaucoma are most strongly linked in the inferior macula, aiding targeted monitoring.

Rao Harsha L, Dasari Srilakshmi, Riyazuddin Mohammed, Puttaiah Narendra K, Pradhan Zia S, Weinreb Robert N et al.

This study found peripapillary OMAG measurements had diagnostic ability for glaucoma, with inferior sector OMAG best correlating with RNFL and visual loss, but were less accurate than RNFL thickness.

OCTA vessel density and diagnostic ability were similar in glaucoma eyes with and without disc hemorrhage. This suggests DH in glaucoma isn't primarily due to vascular issues.

Venugopal Jayasree P, Rao Harsha L, Weinreb Robert N, Pradhan Zia S, Dasari Srilakshmi, Riyazuddin Mohammed et al.

OCTA vessel density repeatability is similar in normal and glaucoma eyes, but higher signal strength significantly increases measured vessel density, impacting clinical interpretation.

This study found that inferotemporal peripapillary vessel density best correlates with optic nerve damage and vision loss in glaucoma, with fractional polynomial models providing superior accuracy over linear models.

Automated pupillography's constriction latency parameters (onset, maximal) best predicted the magnitude of functional and structural glaucoma damage, suggesting its potential as a non-invasive assessment tool.

This study found sex, hypertension, diabetes, and scan quality (SSI) significantly impact OCTA vessel densities in normal eyes, while age and disc size do not, crucial for interpreting glaucoma and retinal disease.

This study found Compass perimetry had more unreliable tests and wide disagreement with HFA in glaucoma patients, meaning these visual field tests are not interchangeable for clinical use.

This study compared OCT angiography vessel density to structural OCT in primary angle closure glaucoma. It found structural changes occur earlier than retinal vessel density reduction, suggesting structural OCT is more sensitive for early detection.

OCTA peripapillary vessel density showed good diagnostic ability for POAG and PACG, comparable to RNFL thickness. This suggests OCTA could be a valuable tool for glaucoma diagnosis.
