Can Baseline Parapapillary Atrophy Morphology Predict Future Glaucoma Progression?-An OCT Glaucoma Imaging Study.

The larger the radial and angular extents of β-zone PPA, the more progression that was shown on OCT GPA. Furthermore, significant differences in progression were noted based on the morphological type of β-zone PPA. Our findings indicate that baseline β-zone PPA parameters and morphology are valuable predictors of future glaucoma progression.
