Participant Flow

22 glaucoma patients were enrolled in this study. However, 7 age, gender and ethnic matched controls were not found for study comparisons. Therefore, only the 15 glaucoma patients who best matched the controls were included in the published analysis.

SECONDARY outcome

Timeframe: 2 hours

Relative volume is calculated by dividing the absolute volume of inferior occipital gyrus L (a location in the brain structure) by that individual's total brain volume.
