Peripapillary ring: histology and correlations
Purpose To assess the histologic correlate of the peripapillary ring (PPR) as the optic disc boundary, to measure it histomorphometrically and to assess its associations with glaucoma and axial length. Methods Using a light microscope, we measured the width of the PPR and optic nerve pia mater. We a...

Zusammenfassung: | Purpose
To assess the histologic correlate of the peripapillary ring (PPR) as the optic disc boundary, to measure it histomorphometrically and to assess its associations with glaucoma and axial length.
Methods
Using a light microscope, we measured the width of the PPR and optic nerve pia mater. We additionally had measured the axial length, length of parapapillary beta and gamma zones, and thickness of the sclera and choroid.
Results
The study included 83 human globes with a mean axial length of 26.1 ± 3.3 mm (range: 20.0–35.0 mm). In the non‐highly myopic (axial length |
