A schema showing the biometric parameters of peripapillary scleral bending measured using swept-source optical coherence tomography. A The distance from the foveal center to the peripapillary scleral bending (white arrow), the distance from the scleral bending to the optic disc edge (yellow arrow), and the distance from the foveal center to the optic disc edge (blue arrow) were measured. Asterisk: scleral bending; Dashed line: fovea B The angle of scleral bending was defined as the angle between two tangential lines drawn along the surface of the sclera on both sides of the bending (yellow line)
