Polarization-Sensitive Optical Coherence Tomography Imaging of Posterior Staphyloma Edges in Eyes With High Myopia.

ABSTRACT:

Purpose

To investigate the arrangement and orientation of the collagen fibers in the inner and outer scleral layers at the edges of posterior staphylomas using polarization-sensitive optical coherence tomography (PS-OCT).

Methods

This observational case series study enrolled 105 patients with high myopia (refractive error <-6.0 diopters or axial length ≥26.5 mm) who underwent PS-OCT examinations between August 2023 and May 2024 at the Institute of Science Tokyo. Posterior staphyloma was diagnosed in 88 eyes of 60 patients using ultra-widefield OCT, followed by PS-OCT image processing. Thirty-six eyes from 27 patients with clearly identifiable staphyloma edges were included for final analysis. PS-OCT images were analyzed to assess the scleral fiber orientation and birefringen
