This study found global OCT metrics for glaucoma progression have high false positive/negative rates due to scanning errors and missing local damage, questioning their clinical utility.

Global circumpapillary RNFL thickness poorly detects glaucoma progression due to local defects and segmentation errors. Clinically, relying solely on this metric is unreliable; image review is crucial.

This study developed an automated method to compare abnormal OCT and visual field regions in early glaucoma. It found specific criteria (OCT <10%, VF <5%) effectively identify structure-function agreement, reducing subjectivity in diagnosis.

This study found current glaucoma staging systems, based on 24-2 visual fields, often miss significant macular damage in glaucoma patients, underestimating disease severity and highlighting the need for improved staging with macular-focused tests.
