Diagnostic ability of the vessel density parameters of OCTA was only moderate.

Diagnostic ability of peripapillary vessel density measurements of optical coherence tomography angiography in primary open-angle and angle-closure glaucoma.

Diagnostic ability of peripapillary vessel density parameters of OCTA, especially the inferotemporal sector measurement, was good in POAG and PACG.

Repeatability of vessel density measurements of optical coherence tomography angiography in normal and glaucoma eyes.

Repeatability estimates of OCTA measured peripapillary and macular vessel densities were similar in normal eyes and eyes with glaucoma.

Determinants of Peripapillary and Macular Vessel Densities Measured by Optical Coherence Tomography Angiography in Normal Eyes.

Most of the peripapillary vessel densities were higher in female subjects.

Vessel Density and Structural Measurements of Optical Coherence Tomography in Primary Angle Closure and Primary Angle Closure Glaucoma.

These results suggest that structural changes in PACG occur earlier than the reduction in retinal vessel densities.

Optical Coherence Tomography Angiography in Glaucoma.

OCTA also adds information about glaucoma patients at risk of faster progression. OCTA, therefore, complements visual field and OCT examinations to diagnose glaucoma, detect progression, and assess risk of progression.

Relationship of Optic Nerve Structure and Function to Peripapillary Vessel Density Measurements of Optical Coherence Tomography Angiography in Glaucoma.

The inferotemporal peripapillary vessel density showed the strongest association with the corresponding retinal nerve fiber layer thickness and visual sensitivity loss in the global and sectoral regions studied.

Choroidal Microvascular Dropout in Primary Open-angle Glaucoma Eyes With Disc Hemorrhage.

Prevalence of CMvD was significantly greater in POAG eyes with DH compared with POAG eyes without DH. CMvD in POAG eyes was also significantly associated with central VF defects and greater severity of glaucomatous damage.

Choroidal Microvascular Dropout in Primary Angle Closure Glaucoma.

Prevalence of CMvD was significantly lower in PACG compared to POAG. As in POAG, CMvD in PACG was associated with advanced VF damage and with IPFS on VF.

Diagnostic Abilities of the Optical Microangiography Parameters of the 3×3 mm and 6×6 mm Macular Scans in Glaucoma.

The outer sector measurements of the 6×6 mm macular OMAG scans seem to be better than the inner sector measurements in diagnosing glaucoma.

A Sectoral Analysis of Vessel Density Measurements in Perimetrically Intact Regions of Glaucomatous Eyes: An Optical Coherence Tomography Angiography Study.

Within the perimetrically intact regions of glaucomatous eyes, the mean VD and RNFL thickness were significantly reduced in inferotemporal, superonasal, and nasal upper peripapillary sectors as compared with healthy eyes (P<0.008).

Optical Coherence Tomography Angiography Vessel Density Measurements in Eyes With Primary Open-Angle Glaucoma and Disc Hemorrhage.

OCT angiography measured vessel densities and their diagnostic abilities in POAG eyes with and without DH were similar. This suggests that the cause of DH in POAG is unlikely to be vascular abnormality.

Choroidal Microvascular Dropout in Pseudoexfoliation Glaucoma.

The prevalence of CMvD was significantly lower in the PXG eyes when compared with the POAG eyes.

A Comparison of the Visual Field Parameters of SITA Faster and SITA Standard Strategies in Glaucoma.

VF parameters with SFR showed good agreement with that of SS strategy. This, combined with low test-retest variability, suggests that SFR can be considered for diagnosis and monitoring of glaucoma.

Diagnostic Ability and Structure-function Relationship of Peripapillary Optical Microangiography Measurements in Glaucoma.

The inferior sector OMAG measurements had the best diagnostic ability in glaucoma and the strongest association with RNFL and the visual sensitivity measurements.

Comparing the Performance of Compass Perimetry With Humphrey Field Analyzer in Eyes With Glaucoma.

The numbers of unreliable tests were higher with Compass compared with HFA.

Optical Coherence Tomography Angiography and Visual Field Progression in Primary Angle Closure Glaucoma.

Lower superficial vessel density measured using OCTA was significantly associated with faster VF progression in PACG. In these eyes, OCTA parameters can serve as biomarker suggestive of past VF progression.

Agreement of a Novel Artificial Intelligence Software With Optical Coherence Tomography and Manual Grading of the Optic Disc in Glaucoma.

The new AI software vCDR measurements had an excellent agreement and correlation with the SD-OCT and manual grading. The ability of the Medios AI to work offline, without requiring cloud-based inferencing, is an added advantage.

Comparison of the Performance of a Novel, Smartphone-based, Head-mounted Perimeter (GearVision) With the Humphrey Field Analyzer.

There was fairly good agreement between the threshold sensitivities of GV and HFA. GV was also preferred by most patients and could potentially supplement HFA as a portable or home perimeter.

Relationship of Macular Thickness and Function to Optical Microangiography Measurements in Glaucoma.

The strongest associations between OMAG, GCIPL thickness, and visual sensitivity measurements were found in the inferior macular sector.

Predicting the Magnitude of Functional and Structural Damage in Glaucoma From Monocular Pupillary Light Responses Using Automated Pupillography.

Glaucomatous damage as estimated by MD, RNFL, and GCC thickness measurements were best predicted by the latency parameters (Loc and Lmaxc) of pupillography.

Optical Microangiography and Progressive Retinal Nerve Fiber Layer Loss in Primary Open Angle Glaucoma.

Lower baseline peripapillary PD and VD measured using OMAG were significantly associated with a faster rate of RNFL loss in POAG.

Predicting the intereye asymmetry in functional and structural damage in glaucoma using automated pupillography.

Intereye asymmetry in MD, RNFL and GCC thickness measurements was best predicted by the intereye difference in Ac per cent on automated pupillography.

Progressive Vessel Density Reduction on OCT Angiography in Glaucoma Eyes with Disc Hemorrhages.

Eyes with POAG harboring a DH showed not only progressive RNFL and GCIPL loss in the DH sector, but also progressive peripapillary and parafoveal VD reduction in the DH and non-DH regions as documented on…

Does the Presence of a Disc Hemorrhage Affect OCT-Measured Vessel Density and Retinal Nerve Fiber Layer Thickness?

The presence of a DH does not artifactually alter the VD or RNFL thickness measurements. Therefore, OCT scans obtained in the presence of a DH may be included in series used for studying progression.

Optical Microangiography and Progressive Ganglion Cell-Inner Plexiform Layer Loss in Primary Open-Angle Glaucoma.

Lower baseline peripapillary OMAG measurements were significantly associated with a faster rate of GCIPL loss in patients with mild to moderate POAG.

Upregulated NOTCH Signaling in the Lens of Patients With Pseudoexfoliation Syndrome Compared With Pseudoexfoliation Glaucoma Suggests Protective Role.

The finding that NOTCH signaling is significantly upregulated in the lens capsule of eyes with PXF and not in PXG or POAG patients suggests a possible protective role in the development of glaucoma.

Optical Microangiography and Progressive Retinal Nerve Fiber Layer Loss in Primary Angle Closure Glaucoma.

Younger patient age and greater peak IOP during follow-up were significantly associated with a faster rate of RNFL loss in PACG patients with mild to moderate severity of functional damage.

Does the ISNT Rule Apply to the Retinal Nerve Fiber Layer?

A larger number of normal eyes obeyed the IST rule compared with the ISNT rule for the RNFL thickness measured by HRT and OCT.
