Rate of Initial Optic Nerve Head Capillary Density Loss and Risk of Visual Field Progression.

Rapid initial optic nerve head capillary density loss from OCTA was associated with a faster rate of visual field progression and a doubling of the risk of developing event progression in this study.

Retinal Nerve Fiber Layer Optical Texture Analysis and 10-2 Visual Field Assessment in Glaucoma.

Papillomacular and papillofoveal RNFL bundle defects are present in a considerable proportion of eyes with glaucoma.

Deep Learning Estimation of 10-2 Visual Field Map Based on Macular Optical Coherence Tomography Angiography Measurements.

DL models enable the estimation of VF loss from OCTA images with high accuracy.

Longitudinal OCTA vessel density loss in macula and optic nerve head in healthy, glaucoma suspect and established glaucoma eyes.

In glaucoma, there is earlier microvasculature loss in the ONH than in the macula.

Differential Impact of Central and Global Visual Field Progression on Quality of Life in Glaucoma.

Central VF change had a greater impact on VRQOL compared to global VF change.

Smoking Intensity is Associated With Progressive Optic Nerve Head Vessel Density Loss in Glaucoma.

A history of greater smoking consumption was associated with faster vessel density loss, suggesting smoking intensity as a potential risk factor for glaucoma.

Racial Differences in the Diagnostic Accuracy of OCT Angiography Macular Vessel Density for Glaucoma.

Diagnostic performance of OCTA macular VD, but not GCC thickness, for glaucoma detection varies by race.

Retinal nerve fibre layer optical texture analysis: retinal nerve fibre bundle defect patterns and the extent of macular involvement across different stages of glaucoma.

ROTA uncovers a wide spectrum of RNFL bundle defects spanning the entire glaucoma continuum.

Proportion of Fast Progressors in the Central versus Global Visual Field Across Varying Glaucoma Severity Groups.

Selective analysis of the MTDdetected a greater proportion of eyes that exhibited fast progression across all disease severity groups compared to measurements from the entire VF, underscoring the importance of close monitoring for progressive central…

Deep Learning Estimation of 24-2 Visual Field Map From Optic Nerve Head Optical Coherence Tomography Angiography.

DL models from OCTA images demonstrated high accuracy in estimating 24-2 VF maps by leveraging information from ONH layers.

Number of macula optical coherence tomography scans needed to detect glaucoma progression.

Increasing the frequency of macular OCT testing to three times per year more sensitively detects progression compared with two times per year.

Association between metformin use with circumpapillary retinal nerve fibre layer thickness and capillary vessel density in glaucoma.

Metformin use was associated with higher wiCD and thicker cpRNFL.

Association of foveal avascular zone change and glaucoma progression.

Significant FAZ increase was weakly associated with moderately faster rates of both GCC thinning and VF MD loss, but not macular vessel density change in glaucoma eyes.
